Moscas ectoparásitas de murciélagos (Diptera: Streblidae y Nycteribiidae) del Valle de Uxpanapa, Veracruz, México.

The diversity of parasitic bat flies (Streblidae and Nycteribiidae) from the Uxpanapa Valley in southern Veracruz, Mexico was studied. We captured bats from 2010 to 2012 in evergreen and secondary forests, as well as in rubber de plantations and caves. A total of 251 out of 378 captured bats were examined. Twenty-six bat species belonging to the families Natalidae, Mormoopidae, Phyllostomidae and Vespertilionidae were found parasitized, and 616 bat flies species from 32 species were collected. Four of the reported bat fly species represent new records for the country: Mastoptera minuta Costa Lima, Trichobius flagellatus Wenzel, Strebla chrotopteri Wenzel (Streblidae) and Basilia ortizi Machado-Allison (Nycteribiidae). Our records expand the geographic distribution for the country for Megistopoda aranea Coquillett, Paratrichobius lowei Wenzel, Speiseria ambigua Kessel, T. costalimai Guimaraes, T. dugesioides Wenzel, T. galei Wenzel, T. hirsutulus Bequaert, T. uniformis Curran, S. alvarezi Wenzel, S. guajiro Garcia y Casal, S. hertigi Wenzel, S. kohlsi Wenzel, and S. wiedemanni Kolenati. These records increase the number of streblid taxa in Mexico to 16 genera and 59 species, 41 of which (69.5%) are reported for the state of Veracruz. Also, the number of Nycteribiidae species reported for Mexico increases to 8, 3 of which were reported for Veracruz.
