Moved from Flies.

I am looking at descriptions of the two known species of Hemeromyia. Can you add a dorsal shot of the thorax including scutellum?

"The presence of discal setulse on mesonotum, the hind femoral preapical bristle, and the different venation should readily separate this species [nitida Malloch = washingtonia Melander] from obscura Coquillett."

I wish I could
but I destroyed this hapless critter while removing its wing for imaging.
I'm excited about this find because it brings Texas into the BugGuide data map and it's a new family for me

Carnidae: Hemeromyia sp.
Carnidae: Hemeromyia sp....there are 2 western species in this genus, but I don't know how to identify them.

Narrow gena
I was looking at Hemeromyia but the gena is supposed to be broader. How about Pholeomyia?

Not Sphaeroceridae
Not Sphaeroceridae because the hind basitarsus is long and thin.

My wild guess was incorrect
Maybe Ephydridae? Two guesses so far. 136 more North American fly families to go... :-)
