I've looked at the keys from Tschorsnig und Herting for this one.
I apologize for my sloppy post with incorrect data.

Following Tschorsnig, I determine this specimen to be auriceps. The discal bristles are the determining factor.

hind tibia without pv bristle:
bicolor, brevicornis, pilipes, rufifrons, xylotina

hind tibia with pv bristle, without apical scutellar bristles:
interrupta, pusilla

hind tibia with pv bristle, with apical scutellar bristles:
auriceps, intermedia

intermedia is supposed to be missing median discal bristles.

Thank You for your time.
