Introduction
The genus Culicoides Latreille, 1809 (Diptera: Ceratopogonidae), known in Mexico as “jejenes or chaquistes”, comprises a large group with 1,347 species worldwide (Borkent & Dominiak, 2020) which is notorious because of its biological, ecological and taxonomic diversity, and is also well known because many species have blood-feeding habits and therefore, medical and veterinary importance (Borkent, 2005; Kettle, 1977; Linley et al., 1983).
Current knowledge of the genus Culicoides in Mexico includes 84 species belonging to 14 subgenera, 9 species groups, and 4 species unplaced (Borkent & Spinelli, 2000, 2007; Huerta et al., 2012; Ibáñez-Bernal et al., 1996; Spinelli & Huerta, 2015). However, the diversity of Culicoides from many regions of Mexico is still poorly studied, and knowledge of the group is still fragmented. The pioneering work of Macfie (1948) described 9 new species from Mexico (Chiapas) and provided a key to species of the Caribbean region, in which at least 28 known species from Mexico can be distinguished. Other taxonomic reviews of Culicoides of the Neotropical region include part of the diversity of species in Mexico (Cf.Blanton & Wirth, 1979; Wirth & Blanton, 1959, 1974; Wirth & Hubert, 1960). Harrup et al. (2015) included identification references for the Culicoides fauna by biogeographical region.
A recent update of the genus Stilobezzia Kieffer, 1911, in Mexico, included a key for all the known species (Huerta & Grogan, 2017). Ronderos and Spinelli (1999) included a review of subgenus Lasiohelea Kieffer, 1921 (Forcipomyia Meigen, 1818) from the Neotropical region, with a key for species known in Mexico.
We report 7 new records from the state of Tabasco: Forcipomyia stylifer (Lutz, 1913), Culicoides blantoniVargas & Wirth, 1955, Culicoides foxi Ortiz, 1950, Culicoides leopoldoi Ortiz, 1951, Culicoides jamaicensis Edwards, 1922, Culicoides poikilonotusMacfie, 1948, and Stilobezzia coquilletti Kieffer, 1917; as well as new locality records for Culicoides gabaldoni Ortiz, 1954, Culicoides insignis Lutz, 1913, Culicoides paraensis (Goeldi, 1905), and Stilobezzia kiefferi Lane, 1947. The distribution record of Culicoides dicrourus Wirth & Blanton, 1955, from Mexico is confirmed. We also include an updated list of known species of Culicoides for the state of Tabasco (Table 1) and a key to separate species from this state.

Materials and methods
A total of 355 specimens of biting midges was collected as part of entomological surveillance of Leishmaniases program, during the first week of October 2019. Collections were performed at peridomestic sites by the personnel of the Secretaría de Salud de Tabasco, Programa de control de vectores del Centro Nacional de Programas Preventivos y Control de Enfermedades (CENAPRECE), in the locality of Huimango (second section), Municipality of Cunduacán, Tabasco, Mexico. Samples of Culicoides, Forcipomyia, and Stilobezzia were collected during a 3-day period with Centers for Disease Control and Prevention (CDC) light traps, in 3 different locations of rural areas near the houses within plantations of Theobroma cacao L., cacao tree. Climate of this collection area is characteristic of the Tabasco plains, warm-humid with abundant summer rains, and an annual average temperature of 26.2 °C (INEGI, 2015). Cunduacán is one of the main cocoa (chocolate) producing regions, with abundant cocoa plantations (cacaotales).
The collection sites were named as: site 1, 18°08’34.8” N, 93°08’66.4” W; site 2, 18°07’56.0” N, 93°10’46.1” W; and site 3, 18°07’97.5” N, 93°10’24.2” W (Fig. 1). Specimens of each species collected were preserved in ethanol and afterwards, separated, cleared, dissected, and mounted on microscope slides in Canada balsam using the technique described by Borkent and Spinelli (2007). A set of remaining specimens was preserved directly in ethyl alcohol.
Morphological terminology here employed is based on Borkent (2017) and Borkent et al. (2009). Assignment of Culicoides species to subgenus and species groups follows the system proposed by Borkent and Dominiak (2020). All specimens are deposited in the Colección de Artrópodos con Importancia Médica (CAIM), Secretaría de Salud, México City.

Discussion
This study increases the biting midge fauna from Tabasco State to 12 species of Culicoides, 2 species of Stilobezzia and 1 species of Forcipomyia (Lasiohelea). However, the study on the fauna of ceratogoponids in the state is still limited (Table 1), and given the different types of vegetation and ecological environments of the state, it is very probable that many more species could be described in the future.
Various Culicoides spp. of medical and veterinary importance are reported (v. gr., C. furens, C. insignis, C. paraensis, and C pusillus). These species are recognized vectors, for being involved in the transmission of viruses and filarial nematodes in the Neotropical region (Borkent & Spinelli, 2007). Entomological surveillance is relevant to detect different species in order to determinate the distribution specific for localities.
