Conopidae- Thick-headed flies, ID Please - Physoconops excisus - female

Conopidae- Thick-headed flies, ID Please - Physoconops excisus - Female
Skidaway Island, Savannah, Chatham County, Georgia, USA
August 7, 2012
This fly was nectaring on Clasping Heliotrope, Heliotropium amplexicaule. I locate what I believe is this species fairly often feeding amongst the shallow nectar sources Dill and Clasping Heliotrope. I believe it is in the genus,"Physoconops or Physocephala" as often noted in BugGuide. Is there an exterior identification point that I might zero in on when photographing that will assist in rendering a genus ID?

Moved from Subgenus Pachyconops.

For a long time I'd been unclear on the confusing situation among the cluster of Florida Physoconops consisting of P. floridanus, P. weemsi, P. excisus, and what seemed to be possibly "disjunct" members of the supposedly southwest species P. townsendi (and apparently I'm not alone in the latter idea...see the last line of this University of Lund record). For instance, your other post below, which exhibits abdominal color mostly red instead of black, seems in that aspect a better candidate for P. townsendi that P. excisus:

 

...except the dark black pattern of the frons (and the East Coast location) are more in line with P. excisus.

But it's become clear to me that some of the posts I was hesitant about (like yours here) are indeed P. excisus. And at this point the "complete post-vertical pollinose stripe" and color pattern characters of the frons, face, thorax, and abdomen I can now confidently place this as P. excisus. (The ones that are still tricky for me are P. weemsi and P. floridanus...but I hope to sort them out too.)
