Biogeography of the Philippine Streblidae (Diptera: Brachycera: Calyptratae)

Abstract

Streblids are obligate, highly specialized haematophagous hippoboscoids that are ectoparasitic bats. These bat flies are largely confined in the subtropics and tropics but no taxa occur in both biogeographic realms. Distributional evidence suggests that the distribution of these taxa is the same as that of their host species. In the Philippines, there are 13 recognized species of streblids belonging to five genera (Ascodipteron, Brachytorsina, Maabello, Megastrebla, and Raymondia) under two subfamilies (Ascodipterinae and Brachytarsininae). Among the five genera, Brachytarsina contains about fifty percent of Philippine endemics. The 4 remaining genera are distributed throughout the Sundaic subregion extending to the Papuan subregion of the Australasian Zoological realm. Among the ecoregions in the Philippines, Greater Luzon (10 species) and Greater Mindanao (7 species) harbour the higher diversity in terms of streblid fauna.
