BG2844 E1227 - Physocephala tibialis
Gloster, Gloster Arboretum, Amite County, Mississippi, USA

Size: body length 13.7 mm.
We think this is a Thick-headed Fly, family Conopidae. Maybe genus Physocephala.
Placement would be appreciated.

Moved from Physocephala.

Moved from Flies. I agree.

Correct.
Correct to family at least. I'm still learning how to tell some of the genera apart with any degree of reliability:-)

 
Physocephala furcillata

 
P. tibialis
This is not P. furcillata, which has facial grooves pale and discal cell hyaline...see couplet 24 of the key in Camras 1996.

The conopid in this post has facial grooves black and discal cell dark, and keys to P. tibialis.

Indeed it is typical of that species in all respects...including having legs mostly pure black with tibiae basally white, and dark (nearly black) humeri. (P. furcillata typically has legs substantial reddish with tibiae basally yellowish, and humeri dusted whitish...though not as widely white as in P. marginata.)

Mississippi is within the range of P. tibialis, an eastern species that reaches west to TX (see info page).
