Looks like...
Episyron. It would be difficult to tell which species from this photo and there are several possibilities. However, I do think placement into Episyron is safe.

Thx Nick
Thanks for the quick ID, Nick. Male or female?? (And how do you tell?)

Male...
I think I can discern thirteen antennomeres so it is a male. Another characters is actually a "gestalt" character: the more robust body proportions of females. There are also differences in body pubescence. Additionally, males have one more sternite than females, but that is rarely visible in typical photos.
