Marshall, Stephen A., 2014, A review of the Afrotropical genus Aristobatina Verbeke (Diptera: Micropezidae: Taeniapterinae), with descriptions of four new species from the Eastern Arc Mountains of Tanzania, African Invertebrates 55 (1), pp. 143-143 : 144

Key for the separation of the genera Tanypomyia and Aristobatina

1. Outer vertical seta present; frontal vitta with large, black, swollen or convex area more than ½ as wide and ½ as high as entire frons ( Fig. 29 ). Fore tarsus entirely white or distal tarsomeres slightly brownish; mid tibia alternately banded with brown and orange or yellow ( Figs 28, 30 ); hind femur flattened, with distinct groove or sulcus. Neither basiphallus nor postgonite extending far beyond base of distiphallus ( Fig. 31 ). Base of each spermatheca with scale­like sculpturing ( Fig. 32 ) ......... ................................................................................................ Tanypomyia Verbeke

– Outer vertical seta absent or present. If present, then frontal vitta with relatively small, dark, swollen area restricted to upper part of frons, lower part of frons broad and orange. Fore tarsus dark distally; mid tibia usually predominantly black, with contrasting orange distal area; if brown with yellow annuli, then outer vertical seta absent; femora and tibiae cylindrical, not distinctly flattened, without longitudinal groove. Basiphallus (of known males) extending far beyond base of distiphallus ( Fig. 5 ). Base of each spermatheca with prominent lobes ( Figs 15–17 ) ...... Aristobatina Verbeke
