Trichoprosopon mixtli sp. nov., a new sabethine species (Diptera: Culicidae) from a Mexican cloud forest, with an assessment of the genus and keys for the identification of known species.

The genus Trichoprosopon Theobald, 1901 includes 13 described species in the Neotropical Region, three of which have been recorded in Mexico. In this work, a new species, Trichoprosopon mixtli sp. nov., is described based on characteristics of the fourth-instar larva, pupa, female and male genitalia, and adults. Larvae and pupae were collected from the flower bracts of Heliconia bourgaeana Petersen at the Instituto de Ecología, A.C. (INECOL), inside the "Santuario del Bosque de Niebla", in Xalapa, Veracruz State, Mexico. This is the first time that the complete larval and pupal chaetotaxy of a species of Trichoprosopon is described. Keys for the identification of known species of Trichoprosopon are provided and the internal classification of the genus is discussed.
