Ascodipteron (Diptera, Nycteribiidae, streblid grade) from China: a new species from the lesser brown horseshoe bat, Rhinolophus stheno

Ascodipteron euryale sp. nov. is described from Yunnan Province, China, based on dealate neosomic females extracted from the base of the ear of the lesser brown horseshoe bat, Rhinolophus stheno K. Andersen, 1905; it is the first record of a species of Ascodipteron Adensamer, 1896 from this bat. Morphological evidence is further supported by molecular data from the cytochrome b (Cytb) and cytochrome c oxidase subunit I (COI) genes.

A detailed comparison of the new species with related species is provided, and the new species is accommodated in the most recent key to the world species of Ascodipteron.
