Diagnosis

Males of Tafana chimire sp. nov. resemble other males of the silhavyi group by the laminar base of the apophysis of the embolus, but differ from them by the base of the retrolateral tibial apophysis with a hook shape apically and the presence of a large basal prominent protuberance on the tegulum ( Fig. 24C–E ).

Etymology

The specific name is a noun in apposition taken from the name of the type locality, Chimire.
