Abstract

An alphabetically-arranged list of all (196) species-group names ever proposed or used in the genus Sceloporus is presented, with citations of the original proposal, onomatophore, type locality, English standard names, current status, combination priority, group assignment, and etymology. Twenty-three species groups, 91 species (66 monotypic) and 153 species- group names are recognized as valid.

Key words: Sceloporus, proposed names, current status.

Introduction

The present compilation deals primarily with the species-group names proposed in the genus Sceloporus. However, it should be noted that the genus itself has been given five names, in chronological order as follows.

Sceloporus Wiegmann, 1828: 369. Type Sceloporus torquatus by subsequent designation (Wiegmann, 1834: 18).

Tropidolepis Cuvier, 1829: 39. Type Agama undulata Daudin (= Stellio undulatus Bosc and Daudin in Sonnini and Latreille), by monotypy (= Sceloporus undulatus undulatus).

Lopherpes Rafinesque, 1832: 143. Type Lopherpes dicyanelus Rafinesque, by monotypy (= Sceloporus undulatus hyacinthinus ). Lopherpes was suggested as a subgenus of Stellio, but adoption at that level was not clear.

Lysoptychus Cope, 1888: 397. Type Lysoptychus lateralis, by monotypy (= Sceloporus variabilis marmoratus).

Sator Dickerson, 1919: 468. Type species Sator grandaevus Dickerson, by original designation (= Sceloporus grandaevus (Dickerson)).

Several species-group names in Sceloporus have been proposed erroneously in other genera: Agama (torquata), Lacerta (fasciata, hyacinthina), and Stellio (undulatus, dicyanelis ?).

At the species-group level, we here recognize 91 species (66 monotypic) and 153 species-group taxa in the genus Sceloporus - a number little different, at least for species, from that recognized by other recent workers. To those 153, 195 species-group names have been applied, 42 of which are junior synonyms or otherwise invalid; one other name (holmani) has been proposed in the genus, but has since been removed to Phrynosoma. We thus here summarize for the first time 196 species-group names that have been applied to the genus, and give basic information about each.

The following names and group assignments that we have adopted is likewise largely that of Wiens and Reeder (1997), with four exceptions detailed in the Comments following the list.

Comments. The nominal subspecies of S. grammicus are those customarily listed, but the names do not properly reflect the taxa that exist in that group, which remain to be clearly defined. Certainly disparilis , as we here treat it, is a distinct species, isolated in a lowland habitad, and occurring on mesquite trees, whereas all others of the complex occur at high altitudes and on evergreen trees. Similarly, tamaulipensis is likely a distinct species, isolated as it is from othesr of its complex. However, to what extent other populations may be isolated and differentiated is not known.

The subspecies listed here of S. minor reflect our interpretationof the analyses by Wiens et al. (1999). It is not clear that molecular studies of conspecific population are always more reliable taxonomically than is morphology.

The ranks of the generally accepted subspecies of undulatus have long been questioned, under the impression that some may be specifically distinct, or that are all invalid. Indeed, Miles et al. (2002) stated that their "results indicate that present subspecies designation do not portray patterns of evolutionary relatedness and require re-evaluation." Their point relative to evolution is well made, but does not prove that the geographic morphological consistency that is the basis for recognition of these subspecies is not genetically correlated and therefore not taxonomically tenable.

Leache and Reeder (2002) likewise analysed molecular systematics of Sceloporus undulatus, but concluded that "at least four lineages should be recognized as evolutionary species." Those four species have little correlation with either environmental conditions or morphology. Both works revealed that the authors gained little or no notion how the subspecies evolved; they did not reveal that the subspecies do not exist.

We hold that species populations that consistently differ at least morphologically from other conspecific populations over a continuous geographic area owe their existence to correlated genetic differences that blend at points of populational contact. They are therefore taxonomically tenable, and their differences are generally assumed to be adaptive, although that assumption has rarely been tested. It is a reasonable hypothesis with no equally reasonable alternative. The fact that those genetic differences usually do not show up with the technology now available does not prove that they do not exist.

The distribution of polytypic species (25 of 91) in Sceloporus, as we understand them, is of considerable interest. On that basis, the groups of the genus are readily divisible into two sections, one polytypic, the other monotypic.

The polytypic division embraces 14 groups: CLARKII, FORMOSUS, GRACIOSUS, GRAMMICUS, LUNDELLI, MAGISTER, MEGALEPIDURUS, MERRIAMI, PYROCEPHALUS, SCALARIS, SPINOSUS, TORQUATUS, UNDULATUS and VARIABILIS. One or two species in each group are polytypic, except for the torquatus group with seven. The total number of species in each group is 1-16, and the percentage of polytypic species in each group varies 13-100%; only those with 1-2 total species have 50-100% polytypic species. The mean number of species per group in this division is 5.2.

The monotypic division embraces 9 groups: ASPER, CHRYSOCEPHALUS, EDWARDTAYLORI, GADOVIAE, JALAPAE, MACULOSUS, OLIVACEUS, SINIFERUS and UTIFORMIS. Each group contains but one or two species, except for olivaceus and utiformis with 3 each, and siniferus with 4; the mean is 1.9 species in this division.

These two divisions are obviously not monophyletic; they merely reveal the characteristics that lend themselves to polytypy. Most species of the monotypic division have a quite restricted range; only the OLIVACEUS and SINIFERUS groups are relatively wide-ranging, but even in them the range of individual species is narrow. Most species appear to have a relictual range, and are relatively small.

Deviations from the groups recognized by Wiens and Reeder (1997) are as follows.

1. Wiens and Reeder (1997: 38) incorporated S. asper in the GRAMMICUS group, Sites et al. (1992:40) gave it a separate group, and Smith (1939: 51) placed it in the FORMOSUS group. Distributionally it meshes best with the latter group (Smith, 1939), morphologically with the GRAMMICUS and TORQUATUS groups (Wiens and Reeder, 1997: 15), and genetically (to the limited extent known) with the GRAMMICUS group. In our opinion it is best regarded as a separate group, as Sites et al. (1992) concluded.

2. S. chrysostictus was placed in its own group by both Smith (1939), and Sites et al. (1992), whereas Wiens and Reeder (1997), as well as Flores-Villela et al. (2000), placed it in the VARIABILIS group. We regard its morphology, so distinctly inconsistent with that of the VARIABILIS group (absence of a postfemoral pocket, presence of larger, imbricate scales on rear of thigh), as justifying retention of the species in a separate group. Its remarkable resemblance to S. cozumelae is best interpreted as convergence through shared selection pressures.

3. S. cautus was placed in the UNDULATUS group by Smith (1939), as was S. exsul when it (Dixon et al., 1972) was described later; Wiens and Reeder (1997) also placed both in the UNDULATUS group. Similarities of both to the SPINOSUS group were noted, and that is where Sites et al. (1992) placed them. However, with segregation of the OLIVACEUS group (Wiens & Reeder, 1997), that is obviously where their relationship lies. Larsen and Tanner (1975) postulated derivation of S. cautus from S. olivaceus, and Ferguson (1982) strongly supported the same conclusion.

4. Flores-Villela et al. (2000) eliminated the ANGUSTUS group, adding its species to the UTIFORMIS group.

LIST OF PROPOSED NAMES

1. acanthinus

Original Proposal: Sceloporus acanthinus Bocourt, 1873a: 1-2; idem, 1874: 180-181. Described twice as new.

Type Locality: San Agustín, 610 m., on the western [southern] slope of Volcán de Atitlán, Guatemala.

Standard Name: Bocourt's Spiny Lizard.

Current Status: Sceloporus acanthinus Bocourt.

Combination Priority: Original.

Group: FORMOSUS, Sites et al. (1992); Wiens and Reeder (1997).

Etymology: An adjective from the Greek akanthinos, meaning "thorny," applied in reference to the bristly appearance of the lizard, due to the elongate spines of the dorsal scales.

Remarks: In the original description, the specific name is spelled acathhinus. However, in the index to the volume, the title of the paper describing the species is given with the name "acanthinus," which is referred to later in the paper. The name acathhinus is an erroneous original spelling without nomenclatural standing.

2. adleri

Original Proposal: Sceloporus adleri Smith and Savitsky, 1974: 297.

Type Locality: Asoleadero, Guerrero, Mexico.

Standard Name: Adler's Spiny Lizard.

Current Status: Sceloporus adleri Smith and Savitsky.

Current Status: Sceloporus aeneus Wiegmann.

Combination Priority: Original, but revived by Liner (1994) and confirmed by Wiens and Reeder (1997), by removal of its subspecies to species rank.

Group: SCALARIS, Sites et al. (1992); Wiens and Reeder (1997).

Etymology: The Latin adjective aeneus, "brazen," or "brassy," was applied referring to the brownish dorsal color of the species.

Remarks: The holotype is so regarded by monotypy, not by original designation.

4. albiventris

Remarks: The name was not published in conformance with Art. 8a(1) ("issued publicly for the purposes of providing a permanent scientific record") of the 1985 International Code of Zoological Nomenclature. The specific issue was brought to the attention of the International Commission on Zoological Nomenclature (Smith et al. 1993), and in the 1999 Code the applicability of the 1985 Article was confirmed and made more explicit that meeting abstracts are not nomenclaturally published.

6. anahuacus

Original Proposal: Sceloporus anahuacus Lara-Góngora, 1983: 2.

Holotype: Originally designated as MZFC 044, collected by G. Lara-Góngora, O. Sánchez-Herrera, and O. Flores-Villela, at 3400 m. Flores-Villela et al. (1991) gave 862 as the number of the holotype, and that number is correct (Flores-Villela, pers. comm.).

Group: PYROCEPHALUS. ORCUTTI according to Sites et al. (1992). PYROCEPHALUS group fide Wiens and Reeder (1997). Name not mentioned in either.

Etymology: This noun, in the genitive plural case, is Latinized from the Spanish barranca, and refers to the habitat on steep-sided canyons. The name is thus properly spelled barrancarum, not barrancorum.

Remarks: Originally named coeruleus (q.v.).

17. becki

Original Proposal: Sceloporus becki Van Denburgh, 1905: 3, 9.

Holotype: CAS 4357, collected 26 March 1903 by R. H. Beck.

Type Locality: San Miguel Island, Santa Barbara County, California.

Standard Name: Island Fence Lizard.

Combination Priority: Original, supported by Bell (2001).

Group: UNDULATUS. HORRIDUS according to Sites et al. (1992), name not mentioned. UNDULATUS fide Wiens and Reeder (1997).

Etymology: The Latin genitive singular honors R. H. Beck, collector of the holotype.

Remarks: The holotype appears to be the only specimen from San Miguel Island available in museum collections. Others, including some paratypes, were destroyed in the San Francisco earthquake and fire of 1906. Most of the Channel Islands, where S. becki occurs, are now a National Park where collecting is rigidly restricted. The taxon was cited as S. occidentalis becki through all of the Stejneger and Barbour checklists (1917-1943), in Schmidt's checklist (1953), by Bell (1954), and by Bell and Price (1996). The Channel Islands populations were regarded by Wiens and Reeder (1997) as probably of specific rank, and so Bell (2001) regarded them. For review see Bell and Price (1996).

18. belli

Original Proposal: Sceloporus undulatus belli Smith, Chiszar and Lemos-Espinal, 1995: 119.

Holotype: UCM 41539, collected 19 June 1966 by Richard L. Holland.

Type Locality: Two mi S León Guzmán, Durango, Mexico.

Current Status: An unavailable junior secondary homonym of Tropidolepis bellii Gray (1831).

Etymology: This noun in the genitive singular case honors Edwin L. Bell, Professor Emeritus of Biology at Albright College, Reading, Pennsylvania, who worked for many years on S. occidentalis and the systematics of the UNDULATUS group.

Remarks: Tropidolepis bellii Gray (1831) was described as a new species, without locality and with a description that precludes certainty of application. It is a nomen dubium. To our knowledge, it has never been cited in the literature; it does not appear in Gray (1845), Boulenger (1885, 1897), or in any more recent work. Tropidolepis Cuvier (1829) is a junior synonym of Sceloporus Wiegmann (1828). Hence Tropidolepis bellii Gray (1831) is transferred to the genus Sceloporus and is a senior secondary homonym of Sceloporus belli Smith et al. (1995). The latter was replaced by edbelli (q.v.).

19. bellii

Original Proposal: Tropidolepis bellii Gray, 1831: 44.

Type: None known.

Type Locality: None given.

Current Status: A nomen oblitum; taxon application unknown, but a secondary senior homonym of Sceloporus belli Smith et al.

Group: uncertain; the description suggests some member of the FORMOSUS group.

Etymology: The patronym honors Thomas Bell (1792-1880), an eminent scientist and herpetologist in London, much admired by Gray, who named many species for him.

20. bicanthalis

Current Status: Sceloporus bicanthalis Smith.

Combination Priority: Original.

Group: SCALARIS. Sites et al. (1992); Wiens and Reeder (1997).

Etymology: The name is derived from the Latin bi, "two", canthus, "edge" or "corner," and -alis, "pertaining to", and refers to the 2-2 canthals of the species, differentiating it from S. aeneus, with 1-1 canthals.

Original Proposal: Sceloporus magister bimaculosus Phelan and Brattstrom, 1955: 9-10.

Current Status: Sceloporus magister bimaculosus Phelan and Brattstrom.

Combination Priority: Original.

Group: MAGISTER. Sites et al. (1992); Wiens and Reeder (1997). Name mentioned in neither.

Etymology: The name is a Latin adjective based upon bis-, "two" or "twice," and maculosus, "spotted," and refers to a series of paired brown blotches on dorsum.

Remarks: This was named Sceloporus magister maculosus in manuscript, and changed to Sceloporus magister bimaculosus while in press, in order to avoid junior homonymy with Sceloporus maculosus Smith (1934b). Unfortunately the name Sceloporus magister maculosus inadvertently persisted in the map of the printed publication. As an incorrect original spelling, maculosus Phelan and Brattstrom has no nomenclatural status. See Parker (1982) for an account under the species name.

Original Proposal: Sceloporus binocularis Dunn, 1936: 474-475.

Etymology: The Greek dis, "double", and kyanos, "blue", refer to the paired blue spots on the sides of the throat.

Remarks: The generic placement of the species in the original account was ambiguous: "Stellio dicyanelis or Lopherpes dicyanelis." A paragraph preceding the description stated "I refer it to the Genus Stellio...but perhaps it might form a S. G. [subgenus] Lopherpes R. [Rafinesque]." This may be one of the earliest uses of the subgeneric category in herpetology.

51. digueti

Group: GRAMMICUS, Sites et al. (1992), Wiens and Reeder (1997). Name not listed in either work.

Etymology: The Latin dispar "unlike," or "different," and -ilis, "having the quality of," refer to the distinctive color and nature of this species.

Remarks: The name has generally been accepted as a nominal subspecies of grammicus, since Smith and Laufe (1945). Occurrence of disparilis sensu stricto in Mexico has not been confirmed, although Texas records are close. It was not reported in the extensive collections from Tamaulipas in the Strecker Museum (Auth et al., 2000).

54. dugesii

Original Proposal: Sceloporus dugesii Bocourt, 1873c: 2; idem, 1874: 188. Described twice as new.

Syntypes: MNHNP 1652-4, collected by Alfredo Dugès.

Standard Name: Dugès' Spiny Lizard, Eastern Dugès' Spiny Lizard.

Current Status: Sceloporus dugesii dugesii Bocourt.

Combination Priority: Smith, 1938a: 657.

Group: TORQUATUS, Sites et al. (1992); Wiens and Reeder (1997), trinominal treed.

Etymology: This name honors the collector, Alfredo Dugès, who often is called "the father of Mexican herpetology", and who was the first one to summarize the Mexican herpetofauna in Linnaean terms.

Remarks: The species may be monotypic; Wiens and Reeder (1997) suggested that its subspecies intermedius may be a species.

55. edbelli

Original Proposal: Sceloporus edbelli Smith, Chiszar and Lemos-Espinal, 2002: 88-90.

Current Status: Sceloporus edbelli Smith, Chiszar and Lemos-Espinal.

Combination Priority: Original.

Group: UNDULATUS. HORRIDUS according to Sites et al. (1992), UNDULATUS fide Wiens and Reeder (1997), through synonymy.

Etymology: The genitive singular name honors Edwin L. Bell, Professor Emeritus of Biology at Albright College, Reading, Pennsylvania, who worked for many years on S. occidentalis and the systematics of the UNDULATUS group.

Remarks: Tropidolepis bellii Gray (1831) was described as a new species, without locality and with a description that precludes certainty of application. It is a nomen nudum. To our knowledge, it has never been cited in subsequent literature; it does not appear in Gray (1845), where it would be expected, nor in Boulenger (1895, 1897) or any more recent work. Tropidolepis Cuvier (1829) is a junior synonym of Sceloporus Wiegmann (1828). Hence Tropidolepis bellii Gray (1831) is transferred to the genus Sceloporus, where it is a senior secondary homonym of the unavailable Sceloporus bellii Smith et al. S. edbelli is its replacement, as a nomen novum.

Type Locality: That of Sceloporus graciosus Baird and Girard.

Current Status: Junior synonym (unjustified emendation) of Sceloporus graciosus.

Group: GRACIOSUS, through synonymy.

Etymology: The Latin words gratia "pleasure", "beauty", and gratiosus "full of favor", are the sources for both spellings; gratiosus is correct, but an incorrect original transliteration (graciosus) is not to be corrected according to the International Code of Zoological Nomenclature.

Group: TORQUATUS. Sites et al. (1992), name not listed; Wiens and Reeder (1997), name treed.

Etymology: The Latin intermedius, "intermediate", was applied with the thought that its scalation was intermediate between that of S. grammicus and S. microlepidotus.

Remarks: Tropidolepis intermedius Dugès (1869: 143) is a nomen nudum. We do not treat it separately because it is the same as the properly published name by the same author. The taxon may be of specific rank (Wiens and Reeder, 1997).

89. internasalis

Holotype: UIMNH 35617, collected 12 March 1953 by Thomas MacDougall.

Etymology: The name, with the Latin -ensis suffix, means "of Irazú, the type locality.

Remarks: The syntypes probably represent more than one species.

91. jalapae

Original Proposal: Sceloporus jalapae Günther, 1890: 74.

Syntypes: BMNH 1946.8.10.31 (formerly 1881.10.31.5), collected by C. T. Hoege.

Type Locality: Jalapa (now Xalapa), Veracruz, Mexico.

Current Status: Sceloporus jalapae Günther.

Combination Priority: Original.

Group: JALAPAE. Sites et al. (1992), Wiens and Reeder (1997).

Etymology: The type locality in the genitive case.

92. jarrovii

Original Proposal: Sceloporus jarrovii Cope in Yarrow, 1875: 569. The name first appeared as a nomen nudum in Cope's (1875) checklist.

Lectotype: USNM 8495, designated by Webb and Axtell (1986), collected by H. W. Henshaw, October 1873.

Type Locality: Webb and Axtell (1986) stated that the type locality "cannot be restricted to one specific site, but is somewhere between Fort Grant and the Fort Bowie National Historic Site, Arizona, in an area encompassing the southeastern Pinaleno (Graham) Mountains, Dos Cabezas, and northwestern Chiricahua Mountains".

Standard Name: Yarrow's Lizard.

Combination Priority: Original.

Group: TORQUATUS. Sites et al. (1992), Wiens and Reeder (1997). Trinominal treed in the latter.

Etymology: The name honors Henry Crecy Yarrow, Acting Assistant Surgeon, United States Army, and Honorary Curator of Amphibians and Reptiles at the U. S. National Museum previous to 1889.

Remarks: Wiens et al. (1999) removed all subspecies from jarrovii except for lineolateralis, which he did not allocate and which we here regard as a separate species.

93. lateralis

Original Proposal: Lysoptychus lateralis Cope, 1888: 397-398.

Holotype: USNM 14741, a typical S. couchi, collected by W. P. Taylor.

Type Locality: San Diego, Duval County, Texas, in error; the species is restricted to Mexico. The type probably came from somewhere in Nuevo León.

Current Status: Junior synonym of Sceloporus couchi Baird.

Etymology: The Latin adjective lateralis, "of the side," probably was based on the very prominent lateral dark and light stripes.

Remarks: The type specimen is preserved in such a manner as to form a definite neck fold (although not of small scales), which was the basis for Cope's new genus. Larsen and Tanner (1975) resurrected Lysoptychus for seven species, including S. couchi, but Cole (1978) returned them to Sceloporus.

94. licki

Original Proposal: Sceloporus licki Van Denburgh, 1895: (2)5: 110.

Holotype: CAS 1436, collected by Gustav Eisen and F. Vaslit, September 1894.

Type Locality: Sierra San Lázaro, Baja California, Mexico.

Standard Name: Cape Arboreal Spiny Lizard.

Current Status: Sceloporus licki Van Denburgh.

Combination Priority: Original.

Etymology: The name honors James Lick, a philanthropist who left his home in Pennsylvania, with little money, became a master cabinetmaker, then went to South America and returned to San Francisco in 1848 with more than $30,000 in gold. He invested in prime waterfront properties and allegedly became the richest man in California. He is buried on Mount Hamilton, beneath one of the piers of Lick Observatory.

95. lineatulus

Original Proposal: Sceloporus lineatulus Dickerson, 1919: 467.

Holotype: Formerly AMNH 5478, now USNM 64263, fide Cochran (1961), collected 16 May 1911 by C. H. Townsend on the Albatross expedition.

Type Locality: Santa Catalina Island, Gulf of California, Mexico.

Standard Name: Santa Catalina Island Spiny Lizard.

Current Status: Sceloporus lineatulus Dickerson.

Combination Priority: Original, restored by Murphy (1983) after long assignment as a subspecies of magister.

Group: MAGISTER. Sites et al. (1992), Wiens and Reeder (1997).

Remarks: Reviewed (as a subspecies of S. magister) by Parker (1982). The taxon was first assigned subspecific rank by Smith (1939), and that was accepted as late as 1990. Species rank was accepted by several workers between 1939 and 1983, but after the latter date most workers followed Murphy (1983).

96. lineolateralis

Original Proposal: Sceloporus lineolateralis Smith, 1936a: 92.

Holotype: FMNH 32002, originally EHT-HMS 4323, collected by E. H. Tylor and H. M. Smith, 27 August 1932.

Type Locality: Six miles northeast of Pedriceña, Durango, Mexico.

Standard Name: Lined Spiny Lizard.

Current Status: Sceloporus lineolateralis Smith.

Combination Priority: Original.

Group: TORQUATUS. Sites et al. (1992), Wiens and Reeder (1997).

Remarks: This was regarded as a subspecies of jarrovii following Webb and Hensley (1959), but Wiens et al. (1999) removed all subspecies from S. jarrovii, except for lineolateralis which he deferred for later consideration. Our experience leads us to regard it as a full species, based on its distinctly different pattern and habitat from S. jarrovii. It was so considered by Wiens and Reeder (1997), and questionably by Sites et al. (1992).

97. longipes

Original Proposal: Sceloporus longipes Baird, 1859: 254.

Lectotype: USNM 4358A, collected by John Xantus, designated by Bell (1954).

Type Locality: Fort Tejon, California [Kern County].

Combination Priority: Bell (1954).

Group: UNDULATUS. HORRIDUS according to Sites et al. (1992). UNDULATUS according to Wiens and Reeder (1997). Name not listed in either work.

Remarks: S. o. longipes is the form sympatric with S. undulatus tristichus in the Pine Valley Mountains of southwestern Utah (Cole, 1983; Smith and Chiszar, 1989). Reviewed by Bell and Price (1996).

98. longipunctatus

Original Proposal: Sceloporus merriami longipunctatus Olson, 1973: 116-127.

99. lunaei

Original Proposal: Sceloporus lunaei Bocourt, 1873c: 1; idem, 1874: 184-186. Described twice as new.

Syntypes: Seven: MNHNP 3144-47.

Type Locality: Plateau of Guatemala, 1500 meters.

Standard Name: Luna's Spiny Lizard.

Current Status: Sceloporus lunae Bocourt.

Combination Priority: Original.

Group: FORMOSUS. Sites et al. (1992), Wiens and Reeder (1997).

Remarks: The Latinized surname Luna becomes lunae in the genitive case, even though Luna was a man. There is no provision in the Code for an extra terminal -i (Art. 31 of the Code, ICZN, 1999).

100. lundelli

Original Proposal: Sceloporus lundelli lundelli Smith, 1939: 66.

Standard Name: MacDougall's Spiny Lizard.

Current Status: Sceloporus macdougalli Smith and Bumzahem.

Combination Priority: Original.

Group: TORQUATUS. Sites et al. (1992), Wiens and Reeder (1997).

Etymology: This Latin genitive singular noun honors the late collector, Thomas MacDougall, who spent many summers collecting plants and some animals in Oaxaca and adjacent states in Mexico.

Original Proposal: Sceloporus poinsettii macrolepis Smith and Chrapliwy, 1958: 268.

Holotype: UIMNH 35455, collected in 1952-3 by Barden and I. L. Firschein.

Type Locality: El Salto, Durango, Mexico.

Standard Name: Western Crevice Lizard.

Current Status: Sceloporus poinsettii macrolepis Smith and Chrapliwy.

Combination Priority: Original.

Group: TORQUATUS. Sites et al. (1992), Wiens and Reeder (1997). Name listed in neither work.

Etymology: The Greek makros, "long," (but often mistakenly, as here, used to mean "large") and lepis, "scale," pertain to the relatively large dorsal scales in this subspecies, compared with other members of the species.

103. maculosus

Holotype: FMNH 32007 (formerly EHT-HMS 7638) collected 29 August 1932 by E. H. Taylor and H. M. Smith.

Type Locality: 14 mi NE Pedriceña, Durango, Mexico.

Standard Name: Northern Snub-nosed Lizard.

Current Status: Sceloporus maculosus Smith.

Combination Priority: Original.

Group: MACULOSUS. Sites et al. (1992), Wiens and Reeder (1997).

Etymology: The Latin noun maculosus, "spotted" or "dappled" refers to the white dots scattered over dorsal surfaces of body and limbs.

104. madrensis

Original Proposal: Sceloporus torquatus madrensis Olson, 1986: 167-170.

Type Locality: Above Rancho del Cielo, 1740 m, 7 km NW Gómez Farías, Tamaulipas, Mexico.

Standard Name: Lesser Torquate Lizard.

Current Status: Sceloporus torquatus madrensis Olson.

Combination Priority: Original.

Group: TORQUATUS. Sites et al. (1992), Wiens and Reeder (1997). Name listed in neither.

Etymology: The Latinized Spanish madre, "mother," and the suffix -ensis, "pertaining to," refer to the type locality of this form in the pine-oak forests on the eastern wall of the Sierra Madre Oriental.

105. magister

Original Proposal: Sceloporus magister Hallowell, 1854: 93.

Holotype: USNM 2967, collected by A. L. Heermann.

Standard Name: Desert Spiny Lizard, Purple-backed Spiny Lizard.

Current Status: Sceloporus magister magister Hallowell.

Combination Priority: Linsdale (1932).

Group: MAGISTER. Sites et al. (1992), Wiens and Reeder (1997).

Etymology: The Latin magister, "master," or "chief," refers to the large size of this species.

Remarks: An excellent history of the confusion between S. magister¨and S. clarkii is given by Stejneger (1893). A review of the species and its subspecies is in Parker (1982).

106. malachiticus

Original Proposal: Sceloporus malachiticus Cope, 1864: 178.

Syntypes: USNM 101062(5), formerly 12186, earlier 6492, collected by C. H. Riotte.

Standard Name: Green Spiny Lizard.

Current Status: Sceloporus malachiticus Cope.

Combination Priority: Original, supported by Wiens and Reeder (1997).

Group: FORMOSUS. Sites et al. (1982), Wiens and Reeder (1997).

Etymology: The Latin malus or melinos, "apple," or apple-green," and the Greek chiton, "tunic," and -icus, "pertaining to," are the roots of this word, and undoubtedly refer to the greenish "tunic" of adult males.

107. marmoratus

Original Proposal: Sceloporus marmoratus Hallowell, 1852: 178.

Holotype: Apparently lost. Cope (1900) noted USNM 2892 as a "type" from San Antonio (under S. variabilis, with which he synonymized it) but it too is lost. Furthermore it is uncertain whether it was the type of delicatissimus or marmoratus, both described by Hallowell on the same page, from the same locality and taken by the same collector, Dr. S. W. Woodhouse.

Type Locality: San Antonio [Bexar Co.], Texas.

Current Status: Sceloporus variabilis marmoratus Hallowell.

Combination Priority: Smith (1934a).

Group: VARIABILIS. Sites et al. (1992), name not listed; Wiens and Reeder (1997), name treed.

Etymology: The Greek marmaros, "marble," and Latin -atus, "pertaining to the nature of," presumably refer to the perceived marble-like appearance of the type.

Remarks: Mendoza-Quijano et al. (1998) elevated this taxon to species rank on the basis of molecular evidence. Morphological intergradation is nevertheless conspicuous, and for that reason we continue to regard marmoratus as a subspecies of variabilis. Degree of difference, whether genetic or morphological, is not a secure criterion of taxonomic rank.

108. megalepidurus

Original Proposal: Sceloporus megalepidurus Smith, 1934b: 272.

Holotype: FMNH 100107 (EHT-HMS 7543), collected 19 July 1932 by E. H. Taylor and H. M. Smith.

Type Locality: Near Totalco, Veracruz, Mexico.

Current Status: Sceloporus megalepidurus megalepidurus Smith.

Combination Priority: Original.

Group: MEGALEPIDURUS. Sites et al. (1992), Wiens and Reeder (1997), trinominal treed in latter.

Etymology: The Greek mega, "large,", lepis, "scale," and oura, "tail," refer to the caudal scales, which are two to three times as large as the body scales.

Remarks. Smith et al. (2000) showed clear evidence of apparent intergradation (hybridization?) between megalepidurus and pictus, but Wiens and Reeder (1997) regarded the relationship as uncertain. Their status remains to be resolved definitively.

109. melanogaster

Original proposal: Sceloporus melanogaster Cope, 1885: 400.

Holotype: USNM 9877,collected by Alfredo Dugès in 1877.

Type Locality: "Probably from Guanajuato." Noría (Michoacán), or Tupátaro near Cuerámaro, Guanajuato, fide Dugès (1888); restricted to Tupátaro by Smith and Taylor (1950).

Current Status: Sceloporus torquatus melanogaster Cope.

Combination Priority: Smith (1938a).

Group: TORQUATUS. Sites et al. (1992), name not listed; Wiens and Reeder (1997), name treed.

Etymology: The Greek melanos, "black," and gaster, "stomach," refer to the black abdomen.

110. melanorhinus

Original Proposal: Sceloporus melanorhinus Bocourt, 1876a: 2-4; idem, 1876b: 401-402. Described twice as new.

Combination Priority: Smith (1942).

Group: CLARKII. Sites et al. (1992); Wiens and Reeder (1997), trinominal treed.

Etymology: The Greek melanos, "black," and rhinos, "nose," refer to the black snout.

111. merriami

Original Proposal: Sceloporus merriami Stejneger, 1904: 17.

Holotype: USNM 33039, collected 2 September 1890 by W. Lloyd.

Etymology: This form honors C. Hart Merriam, the originator of the life-zone theory of biotic ditribution, and chief of the Bureau of Biological Survey, predecessor of the U. S. Fish and Wildlife Service.

Remarks: A review of the species and its subspecies then known is in Olson (1979).

112. microlepidotus

Original Proposal: Sceloporus microlepidotus Wiegmann, 1834: 51.

Syntypes: Ten, ZMB 644-646, collected by F. Deppe.

Type Locality: "Mexico," restricted to Distrito Federal by Smith and Taylor (1950).

Standard Name: Northern Plateau Graphic Lizard see grammicus).

Current Status: Sceloporus grammicus microlepidotus Wiegmann.

Group: GRAMMICUS. Sites et al. (1992), Wiens and Reeder (1997). Name in neither work.

Etymology: The Greek micro-, "small," and lepidos, "scale," refer to the small dorsal body scales.

Remarks: See introductory comments about the grammicus group.

Smith (1949) was the first to use the combination S. m. microlepidotus, but for many years previously the name was used at the monotypic level.

113. mikeprestoni

Original Proposal: Sceloporus torquatus mikeprestoni Smith and Alvarez, 1976: 221.

Holotype: MCZ R115679, an adult female collected by Ticul Alvarez, 3 April 1969.

Type Locality: Marcela, Tamaulipas, Mexico. Marcela is a rural housing development at the northern end of a valley at the foot of Peña Blanca. The nearest town is Miquihuana, Tamaulipas, 19 km N and 7 km W of Marcela.

Standard Name: Preston's Torquate Lizard.

Combination Priority: Original.

Group: TORQUATUS. Sites et al. (1992), Wiens and Reeder (1997). Neither work cited the name.

Etymology: The Latin genitive singular honors Michael J. Preston, who provided critical aid to the Smiths in the processing of data on the literature of Mexican herpetology.

Remarks: Circular sympatry may occur between S. t. mikeprestoni, derived from S. t. torquatus, and S. t. binocularis, derived from S. t. melanogaster. Additional field work in the hiatus between the ranges of S. t. mikeprestoni and S. t. binocularis is necessary to resolve this problem.

114. minor

Original Proposal: Sceloporus torquatus minor Cope, 1885: 402.

Lectotype: USNM 26167, collected by A. Dugès, designated by Webb and Axtell (1994).

Type Locality: "Zacatecas", restricted to Pinos, eastern Zacatecas, by Webb and Axtell (1994).

Standard Name: Minor Lizard, Red Minor Lizard.

Group: TORQUATUS. Sites et al. (1992), name not listed. Wiens and Reeder (1997), jarrovii minor listed.

Etymology: The name is the Latin noun minor, "little," and may have referred to a perceived lesser version of S. torquatus.

Remarks: Monotypic fide Wiens et al. (1999).

115. monserratensis

Original Proposal: Sceloporus monserratensis Van Denburgh and Slevin, 1921: 396.

Type: CAS 50509, collected 24 May 1921 by J. R. Slevin.

Type Locality: Monserrate Island, Gulf of California, Mexico.

Standard Name: Central Baja Spiny Lizard.

Combination Priority: Present; inference might be made from Grismer and McGuire (1996) or Wiens and Reeder (1997), but the combination was actually not made in either work. Considered a geographically distinct pattern class by Grismer (2002).

Group: MAGISTER. Sites et al. (1992), listed as monserratensis; Wiens and Reeder (1997), listed as conspecific with zosteromus and rufidorsum.

Etymology: This taxon is named for its island type locality.

Remarks: A review of S. magister and its subspecies, including monserratensis, is in Parker (1982).

116. mucronatus

Original Proposal: Sceloporus torquatus mucronatus Cope, 1885: 402.

Lectotype: USNM 25077, designated by Smith (1938a), collected by Carl Sartorius.

Type Locality: Mirador, Veracruz, Mexico.

Standard Name: Cleft Lizard, Central Cleft Lizard.

Combination Priority: Smith (1938a).

Group: TORQUATUS. Sites et al. (1992), Wiens and Reeder (1997), trinominal treed in latter.

Etymology: The Latin nominative singular mucronis, "sharp point," and -atus, "pertaining to," refer to the sharply pointed scales on the dorsum.

Remarks: The closely related poinsettii and mucronatus take refuge in rock crevices. The name Crevice Lizard has long been associated with poinsettii; we suggest a verbal synonym, Cleft Lizard, for mucronatus.

117. nelsoni

Original Proposal: Sceloporus nelsoni Cochran, 1923: 185-186.

Holotype: USNM 47676, collected by E. W. Nelson and E. A. Goldman, 18 July 1897.

Group: UNDULATUS. HORRIDUS according to Sites et al. (1992). UNDULATUS fide Wiens and Reeder (1997). The name is not mentioned in either work.

Remarks: The name appeared in a description and discussion of specimens referred to S. biseriatus, noting Hallowell's Sceloporus biseriatus var. azureus, and var. variegatus, to which Bocourt added this third variety.

119. oberon

Original Proposal: Sceloporus jarrovii oberon Smith and Brown, 1941: 253.

Holotype: USNM 105823, collected by H. M. and R. B. Smith, 15 November 1938.

Type Locality: Arteaga, Coahuila, Mexico.

121. occidentalis

Syntypes: USNM 2838, 2866, collected by Dr. J. S. Newberry during the U. S. Exploring Expedition in 1838-1842. No. 2838 is lost, and until 1996 No. 2866 was also thought to be lost (as implied by its absence in Cochran's 1961 list). Accordingly, Bell (1954) designated a neotype, MVZ 59874, collected by Robert C. Stebbins. After discovery of the existence of USNM 2866 (two syntypes), Bell et al. (2001) petitioned the International Commission on Zoological Nomenclature for acceptance of the designated neotype as the name-bearer, rather than the rediscovered syntypes, as required by the Code (ICZN, 1999).

Type Locality: Originally "California, and probably Oregon", restricted to Benicia [Solano County], California, by Grinnell and Camp (1917), by inference from the next published record, by Baird (1859). The designated neotype is from the same locality.

Standard Name: Western Fence Lizard, Northwestern Fence Lizard.

Current Status: Sceloporus occidentalis occidentalis Baird and Girard.

Combination Priority: Camp (1916).

Group: UNDULATUS. HORRIDUS according to Sites et al. (1992), UNDULATUS according to Wiens and Reeder (1997).

Group: SPINOSUS. HORRIDUS according to Sites et al. (1992), SPINOSUS fide Wiens and Reeder (1997). Name mentioned in neither.

Etymology: The Greek words oligo, "few," and poros, "pore," refer to the small number of femoral pores, which rarely total more than six for both sides.

124. olivaceus

Original Proposal: Sceloporus olivaceus Smith, 1934b: 277-278.

Holotype: UIMNH 25057; original EHT-HMS 29883, field no. EHT-2508, taken 23 August 1931 by E. H. Taylor and J. S. Wright.

Standard Name: Texas Spiny Lizard.

Current Status: Sceloporus olivaceus Smith.

Combination Priority: Original.

Group: OLIVACEUS. HORRIDUS according to Sites et al. (1992). OLIVACEUS fide Wiens and Reeder (1997).

Etymology: The Latin oliva, "olive," and -aceus, pertaining to, refer to the olive-green dorsal coloration, particularly of the holotype and other preserved specimens.

Remarks: A review is in Kennedy (1973). A summary of nomenclatural history and confusion is in Axtell (1992).

125. olloporus

Original Proposal: Sceloporus variabilis olloporus Smith, 1937b: 11.

Holotype: UMMZ originally 71207, now 80458, collected 7 October 1931, by Austin Smith.

Standard Name: Southern Rose-bellied Lizard.

Current Status: Sceloporus variabilis olloporus Smith.

Combination Priority: Original.

Group: VARIABILIS, according to Sites et al. (1992) and Wiens and Reeder (1997); name not listed.

Etymology: The Greek ollos, "other," or "of a different sort," and poros, "pore," refer to the relatively small number of femoral pores in the subspecies.

Remarks: Mendoza-Quijano et al. (1998) elevated olloporus to species rank on molecular grounds. Morphological intergradation is nevertheless conspicuous, and for that reason we continue to recognize olloporus as a subspecies of variabilis.

126. olsoni

Original Proposal: Sceloporus mucronatus olsoni Webb, Lemos-Espinal and Smith, 2002: 1-14.

Holotype: UCM 61083 (JLE 4503), collected 6 May 2000 by Julio A. Lemos-Espinal.

Type Locality: Originally "Milquatay Valley, San Diego County, California, just bordering the Mexican boundary, 50 miles east of San Diego by wagon road," correctly rendered "Campo Valley, San Diego County, California". This was an Indian encampment shown on the San Diego County map of 1872 in the Campo Valley. A note signed by L. M. Klauber, dated 14 August 1934 and found in the bottle containing the holotype states "Orcutt once told me that the 'Milquatay' referred to was the flat just east of Campo, San Diego Co., California. Milquatay is said to mean 'wheat field' in Indian, and almost any flat was known as Milquatay. The town of Guatay or Quatay is not the type locality of orcutti" (Hall and Smith, 1979). C. R. Orcutt told L. M. Klauber that the type locality was a few hundred yards east of Campo, San Diego County. (Klauber, 1939).

Current Status: Sceloporus megalepidurus pictus Smith. Sites et al. (1992) noted crosses of megalepidurus and pictus, and Smith et al. (2000) described and mapped intergradation between the two taxa. Wiens and Reeder (1997) regarded the two taxa as separate species, but noted that further study is required for definitive allocation.

Combination Priority: Original.

Group: MEGALEPIDURUS. Sites et al. (1992), Wiens and Reeder (1997).

133. pilsbryi

Original Proposal: Sceloporus pilsbryi Dunn, 1936: 473-474.

Holotype: ANSP 20085, collected in 1934 by Henry A. Pilsbry, Frances W. Pennell and Cyril H. Harvey.

Type Locality: Alvarez, 7500 ft, San Luis Potosí, Mexico.

Current Status: Junior synonym of Sceloporus microlepidotus disparilis fide Smith (1939), in error; pilsbryi is not disparilis as here interpreted, although it is applicable to the grammicus complex. The name may apply to a separate taxon.

Group: GRAMMICUS, Sites et al. (1992), Wiens and Reeder (1997), name not listed.

Etymology: This Latin noun in the genitive singular honors Henry A. Pilsbry, an outstanding conchologist at the Academy of Natural Sciences of Philadelphia in the late 19th and early 20th centuries.

Current Status: Junior synonym of Sceloporus dugesii dugesii fide Smith (1938a).

Group: TORQUATUS. Sites et al. (1992), Wiens and Reeder (1997), name not listed.

Etymology: The Greek pleura, "side," and lepis, "scale," refer to the lateral scales, which "are twice or thrice as large as those on the back, and keeled" (Günther, 1890: 74).

134. pleurostictus

Original Proposal: Sceloporus pleurostictus Wiegmann, 1828: 370.

Type: Presumably ZMB (but not listed in Taylor, 1969), Ferdinand Deppe collector.

Type locality: "Mexico", restricted to Chilpancingo, Guerrero, Mexico, by Smith and Taylor (1950).

Current Status: Junior synonym of S. grammicus fide Smith (1939).

Etymology: The Greek pleura, "side," and stiktos, "spotted" refer to the scattered dark spots on sides of body.

Remarks: The taxon to which this name applies is likely the same as that represented by rubriventris, if the type locality restriction here cited is accepted. Further study of the GRAMMICUS complex will be necessary to establish definitively the taxa to which these names apply.

135. plioporus

Original Proposal: Sceloporus serrifer plioporus Smith, 1939a: 212.

Holotype: FMNH 32004, collected by E. H. Taylor, no date.

Current Status: Sceloporus prezygus Smith.

Combination Priority: Original, but supported by Wiens and Reeder (1997), and questionably by Sites et al. (1992).

Group: TORQUATUS. Sites et al. (1992), Wiens and Reeder (1997).

Etymology: The Latin pre-, "going before," and Latinized form of Greek zygos, "yoked," refer to the phylogenetic position of the species, thought to have been near the ancestral origin of the poinsettii group.

Remarks: The Standard name is a reflection of the fact that prezygus was often regarded as a subspecies of serrifer, following Axtell (1960).

Original Proposal: Cope, 1871: 80.

Current Status: A nomen nudum, with no nomenclatural standing. It probably was intended to apply to S. squamosus.

Etymology: The Latin noun pullus, "young," may reflect a thought by Cope that the specimen at hand was immature.

141. pygmaeus

Original Proposal: Sceloporus pygmaeus Lara-Góngora, 1978: 26.

Current Status: An unavailable name (not published under the criteria for nomenclatural acceptance), applied to what later was acceptably named Sceloporus anahuacus Lara-Góngora (1983).

Etymology: The name is the Latin adjective pygmaeus "pygmy-like, dwarfish," applied in reference to the small size of the species, "never exceeding 54 mm. [SVL]" (Lara-Góngora, 1983).

Group: GRAMMICUS, through synonymy.

Remarks: See remarks under altamontanus. The name Sceloporus pygmaeus holds the same relationship to Sceloporus anahuacus as Sceloporus altamontanus does to Sceloporus palaciosi.

Original Proposal: Sceloporus pyrocephalus Cope, 1864: 177.

Lectotype: USNM 31495, collected by John Xantus in 1863, was stated by Cochran (1961) to be the lectotype. We are aware of no other designation.

Type Locality: Near Colima, Colima, Mexico.

Standard Name: Red-headed Spiny Lizard.

Current Status: Sceloporus pyrocephalus Cope.

Combination Priority: Original.

Group: PYROCEPHALUS. ORCUTTI according to Sites et al. (1992). PYROCEPHALUS, Wiens and Reeder (1997).

Etymology: The Greek pyro-, "fire," and kephale, "head," refer to the reddish head coloration, especially in females.

143. pyrrhocephalus

Onomatophore: same as for pyrocephalus, for which pyrrhocephalus was an emendation.

Current Status: An unjustified emendation and an objective junior synonym of pyrocephalus. It is an available but invalid name.

Group: PYROCEPHALUS, through synonymy.

Etymology: The Greek pyrrho-, "red," and kephale, "head," mean "red-headed," as opposed to pyrocephalus, "fire-headed". The name pyrrhocephalus was used consistently, with two exceptions, after it was proposed, until 1937, but pyrocephalus has been used consistently since then, and under the circumstances is correct under the International Code of Zoological Nomenclature.

144. robisoni

Original Proposal: Sceloporus striatum Sorenson, 1894: 163, 170.

Group: Uncertain, probably UNDULATUS.

Etymology: The Latin noun stria, "furrow," or "channel," and suffix -atus, "pertaining to," perhaps referred to the arrangement of the dorsal scales in rows.

Remarks: This name was applied to specimens of Sceloporus in a neurological study of the epiphysis and parietal eye. It therefore was accompanied by a description, but it did not purport to differentiate the taxon (Art. 13 of the Code, ICZN, 1999).

167. stuarti

175. teapensis

Original Proposal: Sceloporus teapensis Günther, 1890: 75.

Type Locality: Teapa, Tabasco, Mexico.

Standard Name: Teapan Rose-bellied Lizard.

Current Status: Sceloporus teapensis Günther.

Combination Priority: Original.

Group: VARIABILIS. Sites et al. (1992), as a subspecies of S. variabilis). Wiens and Reeder (1997), as a species.

Etymology: This species is named for its type locality, Teapa, with the Latin suffix -ensis, meaning "of".

Remarks: Authorities differ on the rank of this taxon. Smith (1937b) regarded it as a subspecies, but later (Smith, Pérez-Higareda and Chiszar, 1993) as a species. The most recent analysis (Mendoza-Quijano et al., 1999)considers teapensis as a subspecies of variabilis. More field work is needed in the area of range contact.

176. tedbrowni

Original Proposal: Sceloporus undulatus tedbrowni Smith, Bell, Applegarth, and Chiszar, 1992: 124.

Type Locality: A large dune, Waldrop Peak, 0.5 mi S Hy 380, Chavez Co., 6 mi W Caprock, Lea Co., New Mexico.

Group: UNDULATUS. HORRIDUS group according to Sites et al. (1992), UNDULATUS fide Wiens and Reeder (1997). Name not listed in either work.

Etymology: This name honors Col. Sylvanus Thayer, founder of the instructional regimen at West Point Military Academy in the middle of the 19th century.

Remarks: If the syntypes came from as far-flung places as stated in the original description, they represent more than one taxon.

178. torquata

Original Proposal: Agama torquata Peale and Green, 1830: 231-232.

Holotype: ANSP 8499, collected by W. H. Keating.

Type Locality: "Mexico", restricted to México, Distrito Federal, by Smith and Taylor (1950).

Current Status: Junior secondary homonym and objective synonym of Sceloporus torquatus Wiegmann (1828).

Etymology: See torquatus entry.

Remarks: Serendipitously, Peale and Greene applied the name to the same species as Wiegmann did.

179. torquatus

Original Proposal: Sceloporus torquatus Wiegmann, 1828: 369.

Syntypes: Five: ZMB 628-631, collected by Ferdinand Deppe.

Type Locality: Mexico, restricted to México, Distrito Federal, by Smith and Taylor (1950).

Standard Name: Torquate Lizard, Wiegmann's Torquate Lizard.

Current Status: Sceloporus torquatus torquatus Wiegmann.

Combination Priority: Cope (1885).

Etymology: The Latin torquatus, "adorned with a necklace or collar", refers to the conspicuous, light-bordered black collar in these lizards.

Remarks: This is the type species of Sceloporus, so designated by Wiegmann (1834). Smith (1938a: 539) proposed that the TORQUATUS group be called the POINSETTII group because the name torquatus Wiegmann was at one time a secondary homonym, and under the nomenclatural rules then in effect, suppression of any homonym, primary or secondary, was considered permanent. For that reason the name Sceloporus ferrariperezi Cope (1885), as the earlist available synonym, was revived for S. torquatus Wiegmann. Unhappy with that arrangement, Smith and Taylor (1950:121) noted that secondary homonyms have not "been regarded in recent years as permanently suppressed", and on that basis revived TORQUATUS as the group name, and torquatus as the species name. That nomenclature has remained in effect to the present time, although not until the 1961 Code appeared was the later reasoning made official. Ditmars (1933) used the name "porcupine lizard" for this species. Olson (1990) reviewed the species and its subspecies.

180. transversus

Original Proposal: Sceloporus magister transversus Phelan and Brattstrom, 1955: 10.

Holotype: CAS 91200, formerly UCLA 6695, collected 23 July 1953 by R. L. Phelan.

Type Locality: Keough's Hot Springs, 7 mi. S Bishop, Inyo County, California.

Standard Name: Barred Spiny Lizard.

Current Status: Sceloporus magister transversus Phelan and Brattstrom.

Combination Priority: Original.

Etymology: The Latin noun transversus, "crosswise," refers to the 6 or 7 conspicuous dark crossbars on the dorsum.

Original Proposal: Sceloporus scalaris unicanthalis Smith, 1937c: 4.

Holoype: FMNH 100101, formerly EHT-HMS 7699, collected by H. M. Smith, 30 June 1935.

Type Locality: Magdalena, Jalisco, Mexico.

Standard Name: Southwestern Bunchgrass Lizard.

Current Status: Sceloporus scalaris unicanthalis Smith.

Combination Priority: Original.

Group: SCALARIS. Sites et al. (1992), name not listed. Wiens and Reeder (1997), name treed.

Etymology: The Latin unus, "one," the Greek canthus, "corner," and the Latin suffix -alis, "pertaining to," refer to the distinctive single canthal scale.

Original Proposal: Sceloporus magister uniformis Phelan and Brattstrom, 1955: 7.

Holotype: CAS 91201 (formerly UCLA 1812), collected 14 June 1943 by R. B. Cowles.

Etymology: This form is named for the type locality, with Latin suffix ensis, "of".

186. utiformis

Original Proposal: Sceloporus utiformis Cope, 1864: 177.

Syntypes: Two: USNM 42089, near Colima, Colima, Mexico, collected by John Xantus in 1863, and USNM 42090, near Cachán River, Michoacán, Mexico.

Standard Name: Antesator.

Current Status: Sceloporus utiformis Cope.

Combination Priority: Original.

Etymology: Cope stated that utiformis "approaches Uta in its scutellation." To that name he added -formis, from Latin forma, shape or figure. At that time Uta included Urosaurus of today.

Combination Priority: Original.

Group: UTIFORMIS. Sites et al. (1992), Wiens and Reeder (1997), Flores-Villela et al. (2000).

Remarks: Wiens and Reeder (1997) showed that utiformis is the closest relative to the species of the former Sator, hence the suggested Standard Name.

187. vallaris

Original Proposal: Sceloporus clarki vallaris Shannon and Urbano, 1954: 189-191.

Type Locality: Granite Dells, four miles north of Prescott, Yavapai County, Arizona.

Standard Name: Plateau Spiny Lizard.

Current Status: Sceloporus clarkii vallaris Shannon and Urbano.

Combination Priority: Original.

Group: CLARKII. Wiens and Reeder (1997), Sites et al. (1992); name not listed.

Etymology: The Latin vallum, or vallaris, i.e., a rampart, mound or wall, refers to the habitat on the Colorado Plateau of Arizona among large granitic boulders.

188. vandenburgianus

Original Proposal: Sceloporus vandenburgianus Cope, 1896: 834.

Holotype: USNM 21931, collected by E. A. Mearns, 20 June 1894.

Standard Name: Southern Sagebrush Lizard.

Current Status: Sceloporus graciosus vandenburgianus Cope.

Combination Priority: Camp (1916).

Group: GRACIOSUS. Sites et al. (1992), name not listed. Wiens and Reeder (1997), listed as a full species.

Etymology: The Latin genitive singular honors John Van Denburgh, whose 1922 two-volume set, The Reptiles of North America, laid the foundation for herpetology in the American West. He was Curator of the Reptile Collection at the California Academy of Science from 1895 until his untimely death in 1924.

Remarks: Censky (1986) reviewed S. graciosus and its subspecies. Wiens and Reeder (1997) were equivocal in giving vandenburgianus species rank (originally proposed by Collins, 1991), but Collins and Taggart (2002) and Grismer (2002) accepted it. However, Applegarth and Banta (1970) provided considerable evidence of intergradation with graciosus, hence we prefer to retain subspecific rank.

189. variabilis

Original Proposal: Sceloporus variabilis Wiegmann, 1834: 51.

Syntypes: Seven: ZMB 650-653, Ferdinand Deppe collector.

Group: VARIABILIS. Sites et al. (1992), Mendoza-Quijano et al. (1998), Flores-Villela et al. (2000), Wiens and Reeder (1997). The latter also treed the trinomen.

Etymology: The Latin adjective variabilis, "changeable, or "variable" refers to the "wide difference in color between the males and females" (Cope, 1900).

Remarks: A review is in Mather and Sites (1985). Mendoza-Quijano et al. (1998) regarded the upland Mexican populations as a distinct species, as yet unnamed.

190. variegatus

Original Proposal: Sceloporus occidentalis var. b, variegatus Hallowell, 1854: 94.

Type: apparently lost.

Current Status: Junior synonym of Sceloporus occidentalis biseriatus fide Bell (1954).

Group: UNDULATUS. HORRIDUS according to Sites et al. (1992). UNDULATUS fide Wiens and Reeder (1997). Name not listed in either work.

Remarks: A review is in Cole (1968).

192. viviparus

Original Proposal: Sceloporus viviparus Cope, 1885: 398.

Holotype: USNM 25073, collected by C. Sartorius.

Original Proposal: Sceloporus westphalii Dugès, 1877: 30.

Current Status: The name is not available, cited but not adopted in the description of S. dugesii intermedius.

Group: TORQUATUS. Sites et al. (1992), Wiens and Reeder (1997), name not cited in either work.

Etymology: The Latin genitive singular honors a friend of Dugès named Westphal, who "Quería haberle dado el nombre de Sc. Westphalii." However, having already referred to the taxon as Tropidolepis intermedius (Dugès, 1869), he felt bound to retain that name even though it was originally a nomen nudum.

194. williamsi

Original Proposal: Sceloporus merriami williamsi Lemos-Espinal, Chiszar, and Smith, 2000: 93.

Holotype: UIMNH 52378, taken by K. L. Williams, E. O. Moll, F. Vuilleumier, and J. E. Williams, 31 August 1962.

Remarks. The patronym honors Kenneth L. Williams, long a specialist in the classification of snakes and the herpetology of Mexico and Honduras. In the original description, two spellings of the name appeared: willaimsi and williamsi. We here designate the latter as correct.

195. woodi

Original Proposal: Sceloporus woodi Stejneger, 1918: 90.

Holotype: USNM 48720, collected by Nelson R. Wood in 1912.

Type Locality: Auburndale, Polk Co., Florida.

Standard Name: Florida Scrub Lizard.

Combination Priority: Original.

Group: UNDULATUS. HORRIDUS according to Sites et al. (1992). UNDULATUS according to Wiens and Reeder (1997).

Etymology: The Latin genitive singular honors Nelson R. Wood, collector of the type specimen, and contributor of other herpetological specimens to the United States National Museum.

Remarks: A review is in Lee and Funderburg (1977).

196. zosteromus

Original Proposal: Sceloporus zosteromus Cope, 1863: 105.

Syntypes: USNM 5298(23), and 69472-88, collected by John Xantus.

Type Locality: Cape San Lucas, Baja California, Mexico.

Standard Name: Baja Spiny Lizard, San Lucan Spiny Lizard.

Combination Priority: Present.

Group: MAGISTER. Sites et al. (1992), Wiens and Reeder (1997).

Etymology: The Greek zoster, "belt or girdle," and the Latin suffix -ome, "pertaining to the nature of," refer to the black inguinal blotches anterior to the thighs, connecting with black areas on the venter.

Remarks: Grismer and McGuire (1996) concluded that an interbreeding continuity of populations, often referred to as S.monserratensis, S. rufidorsum, and S. zosteromus, extends throughout most of Baja California; hence they are conspecific (as was thought by Smith, 1939). Wiens and Reeder (1997) agreed, but in neither work were the trinominals used. Grismer (2002) regarded the three populations as pattern classes rather than subspecies. A review is in Parker (1982).
