KEY TO AFROTROPICAL GENERA OF STICHOPOGONINAE

1 Pulvilli present, even if only poorly developed.................................. 3

— Pulvilli absent........................... 2

2 Cell m3 closed; mystacal setae circular in cross-section............. Turkmenomyia Paramonov, 1930

— Cell m3 open; mystacal setae dorsoventrally flattened.............. Rhadinus Loew, 1856

3 Pulvilli poorly-developed, about half length of claw; currently confined to Kenya ........................ Nanoculcita gen. n.

— Pulvilli well-developed, almost reaching distal end of claw........................ 4

4 Two well-developed ocellar macrosetae present; cell m3 with a long stalk at base; usually small, or even tiny flies (<10 mm); habitat sandy banks of streams, rivers, and lakes................ Stichopogon Loew, 1847

— Ocellar macrosetae weak or absent; cell m3 with a short basal stalk, or none........... 5
