They end of the keys says:
Villa: Fore tibiae with short bristles, spiculate; pulvilli absent; wing with at most a narrow basicostal infuscation, male often with a patch of silvery scales at its base; usually with extensive yellowish hair, especially on thorax; abdomen with a more or less distinctly banded pattern and one or more pairs of tufts of black scales at sides.
Villa is a large, cosmopolitan genus of mostly very similar looking species, some of which can only reliably be separated by differences in the genitalia.
Hosts: Immatures have been recorded as internal parasitoids of the pupae of Lepidoptera, Tabanidae and Myrmeleontidae.
Distribution: Cosmopolitan. Africa South of the Sahara: 43 species.
I'd say these are all perfect Villa spp.
