Ataenogera brevicornis Bromley

( Figs. 20–29 , 57 )

brevicorni s Bromley (1934:361, desc.) ( Henicomyia ), Webb and Irwin (1989:39, syn. of abdominalis ), Irwin and Webb (1992:86, checklist) ( Ataenogera ). Type locality Guyana [ British Guiana], Bartica District, Kartabo. Holotype female in AMNH.

Diagnosis. Ataenogera brevicornis is similar to A. abdominalis in possessing lanceolate setae on male tergite 7 and sternites 5–8 and female sternites 5–7. Ataenogera brevicornis differs from A. abdominalis in having the frons dark reddish brown, and completely covered with light gray pubescence ( Figs. 20–21 ); in possessing one pair of dorsocentral macrosetae; in having the forefemur dark yellowish brown; and the male hypandrium setose ( Fig. 23 ).
