Key to adults of the species of Auloceromyia

1. Scutum with yellow dorsolateral bands connecting to yellow postpronotal lobes and postalar calli ( Figs 7–8 ); M3 concave, discal cell much more longer than high ( Figs 11– 12 ; Pimentel & Pujol 2000, Figs 8 , 18 ); hind femur and basitarsus slender, like those of other legs, not enlarged in females................................................................. 2

- Yellow dorsolateral bands considerably reduced to peripheral areas of scutum or almost invisible ( Figs 9, 10 , 34 ); M3 nearly straight, discal cell as long as high ( Figs 13–14 ); hind femur and basitarsus enlarged in females...... A. pachypoda nov. sp.

2. Eyes with conspicuous and dense pilosity ( Lindner 1969, Fig. 8 ); third sector of discal cell shorter than r–m ( Pimentel & Pujol 2000, Fig. 18 ); second segment of abdomen partially whitish.................................. A. vespiformis Lindner

- Eyes with inconspicuous and very short pilosity; third sector of discal cell as long as r–m ( Figs 11–12 ; Pimentel & Pujol 2000, Fig. 8 ); second segment of abdomen almost entirely whitish, except for lateral margins dark brown to black........................................................................................
