The new genus Imelda is described with Aphodius constricticollis as the type species. Aphodius (Trichonotuloides) fossulatipennis Balthasar, 1945 is considered a junior synonym of Trichonotuloides latecrenatus (Bates, 1887); and Aphodius omiltemius Bates, 1889 is placed as a junior synonym of Cephalocyclus mexicanus (Harold, 1862). Lectotypes and paralectotypes are designated where necessary.

Introduction

The present work is intended to update the systematics and nomenclature of Aphodiinae taxa listed by Bates in the volume II (1887) and supplement (1889) of the Biologia Centrali-Americana. The study is based primarily on the types preserved in Bates' collection at the Natural History Museum, London and on typical material preserved in Harold's and Oberthür's collections at the Muséum d'Histoire Naturelle, Paris. The latter institution contains duplicates from the Bates collection including material from Champion, Höge and Sallé.

Most specimens examined were carefully labelled and, if not, old locality names and political subdivisions are updated following the excellent work of Selander & Vaurie (1962).

Also included are collection records of specimens preserved in:

- Canadian National Collection of Insects, Division Agriculture, Ottawa (CNC).

- Dellacasa Collection, Genoa (Italy) (DCG).

- Instituto de Ecología, Xalapa (Veracruz, Mexico) (IEX).

- Louisiana State University, Insect Collection, Baton Rouge (U.S.A.) (LSU).

- Museo di Storia Naturale e del Territorio, Università di Pisa, Calci (Pisa) (MSNTC).

- Muséum National d'Histoire Naturelle, Paris (MNHNP).

- Natural History Museum, London (NHML).

- United States National Museum of Natural History, Washington, (DC, USA) (USNM).

Each taxon is either redescribed using all character systems, including epipharyngeal and aedeagal features, or the bibliographical references in which the taxon has been redescribed are included.

Bates (1887, 1889) described or recorded the following taxa that are listed in the same systematic order as in his publications. This order is compared directly to the current status as recognized by subsequent authors.

- NICARAGUA: Greytown, Chontales (Bates, 1887: 83).

Remarks: Except for some slight differences in epipharyngeal features (e.g.: pedia pubescent toward corypha only), the complex of anatomical characters indicates that Aphodius sallei and Aphodius lansbergei belong to the genus Agrilinus as delimited in a paper by Dellacasa G. et al. (2001).

Also, based on collecting experiences by one of us (Dellacasa M.), we can state that Agrilinus sallei is commonly collected in low lying areas whereas Agrilinus lansbergei seems to prefers higher altitudes (above 1000 m).

Remarks: Some morphological characters (e.g.: frontal suture, in males, feebly tuberculate) and the aedeagal structure show significant differences if compared with those of Agrilinus taxa as delimited in a paper by Dellacasa G. et al. (2001). We do not describe a new genus for this species because several North American taxa seem to belong to azteca group and must be assessed prior to systematic redefinition at genus-group level.

Remarks: This species is not a member of Pharaphodius (type species: Aphodius marginellus Fabricius, 1781) as delimited in a paper by Dellacasa G. et al.(2001). We refrain from describing a new genus because of the uncertain systematic position of many taxa at present considered to be in Pharaphodius.

Remarks: Blackwelder (1944) recorded this species from U.S.A. but all specimens from this country, examined by one of us (Gordon) were misidentified. Along with several North American taxa, the complex of epipharyngeal and aedeagal features indicates that this taxon belongs to the genus Liothorax (type species: Aphodius plagiatus Linné, 1767) as delimited in a paper of Dellacasa G. et al.

Remarks: As noted by Bates (1887: 86), the study of both coloradensis and flohri types seems to confirm the above synonymy but some slight differences in habitus and aedeagal features indicate that subspecific entities may exist. To settle the question it is obviously necessary to examine large series of specimens from many localities throughout the distributional range.

Remarks: The genus-group Agoliinus, as delimited in the paper by Dellacasa G. et al. (2001), contains taxa with hind tibiae apically fimbriate with short and equal spinules. Aphodius cruentatus has hind tibiae apically fimbriate with rather elongate and alternately unequal spinules, but most of morphological as well as aedeagal and epipharyngeal characters indicate that this taxon may be assigned, at least at present, to Agoliinus.

For the taxon listed by Bates (1889) as "16 (A). Aphodius constricticollis" we herein create the new genus:

Genus IMELDA nov.

Species mediae, elongato-oblongae, parum convexae, glabrae, politae. Obscure piceae. Capite epistoma parum convexo; clypeo antice subtruncato, lateribus late rotundato; genis parum prominulis; oculis satis latis; sutura frontali mutica. Pronoto modice convexo, subquadrato, disco laevissimo, lateribus et dupliciter et crebre punctato; lateribus post mediun paullo constricto apudque subrectos angulos posticos iterum paullulum dilatato; basi marginata. Scutello parvo, triangulariter elongato. Elytris ovalibus, humeribus valde denticulatis; striis subtilis, subcrenulatis; interstitiis planiusculis fere impunctatis. Metatibiis setis apicalibus longitudine alterne inaequalibus.

Description: medium size species (length 7-8 mm), oblong-elongate, feebly convex, glabrous, strongly shiny. Dark piceous. Head with epistome feebly convex, nearly impunctate; clypeus anteriorly subtruncate, widely rounded at sides, thinly bordered, border glabrous; genae feebly more protruding than eyes; latter rather large; frontal suture not tuberculate at all. Pronotum moderately convex, subquadrate, smooth on disc, doubly coarsely punctured on sides; latter thickly bordered, somewhat angustate before posterior right angles somewhat protruding outwardly; base distinctly bordered. Scutellum small, triangularly elongate. Elytra oval-elongate, feebly convex, strongly denticulate at shoulder; striae fine, subcrenulate; interstices flat, nearly impunctate. Pygidium glabrous, irregularly punctured, on apical margin with four elongate setae. Fore tibiae distally tridentate and proximally serrulate at outer margin; upperside densely and rather coarsely punctured. Middle and hind tibiae with feeble transverse carinae on outer face; apically fimbriate with near regularly alternate unequal spinules. Sexual dimorphism shown in males by fore tibiae apical spur stouter and obtusely rounded apically, by metasternal plate concave and relatively more densely punctured. Epipharynx broadly transverse, distinctly sinuate at middle of irregularly setigerous anterior margin and subsinuate at widely rounded sides; epitorma pyramid-shaped with two longitudinal rows of short spines; corypha with two very strong apical spines moderaley protruding beyond front margin; pedia densely pubescent, with several spinules rather irregularly arranged antero-laterally; chaetopariae moderately elongate and almost dense.

Distribution: Mexico.

Derivatio nominis: named in honour of Dr. Imelda Martínez, biology researcher at Instituto de Ecologia in Xalapa (Veracruz). The taxon name is feminine.

Remarks: The new genus belongs to the groups of taxa characterized by: scutellum small, triangular; hind tibiae apically fimbriate with alternately unequal spinules; pronotum bordered at base.

The most evident characteristics are the lateral margins of the pronotum inwardly sinuate before hind angles, and the elytral humeri strongly denticulate. These distinctive characters are not simultaneously present in other genus-group taxa showing the same basic characters.

Remarks: Most of the Mexican specimens examined appear less shiny than typical guatemalensis owing to stronger microreticulation. It is possible that Mexican populations represent a subspecies instead of only a colour variation. Obviously it is necessary to examine large series from different localities to ascertain the taxonomical level and distributional limits of the taxon.

Distribution from literature:

- MEXICO: San Pedro in Coahuila, Villa Lerdo in Durango (Bates, 1887: 90).

Remarks: Bates (1887) described Aphodius bifrons from San Pedro in Coahuila and from Villa Lerdo in Durango. Based on Horn's advice, he later (1899) he synonymized this taxon with Aphodius larreae Horn, 1887. Though most specimens examined were collected at light, Horn reported in his original description that larreae was "taken [....] on the flowers of Larrea mexicana". Aedeagal, epipharyngeal and other morphological characters place this species in the genus Drepanocanthoides (type species: Aphodius walshii Horn, 1870) as delimited in a paper by Dellacasa G. et al. (2001).

The two taxa can be keyed as follows:

Nota

¹ The Central American species herein illustrated are placed into the genus Blackburneus, sensu lato. However, the aedeagus of these species has elongate and apically pubescent paramera whereas in the type species of the genus (Blackburneus furcatus Schmidt A., 1909) they are rather short and apically glabrous. The epipharynx of the type species has the same structures as do the Central American species.
