Hello,
I have the following female Dolichopodidae from Lesvos, Greece. Using Grichanov 2007 I managed to identify the genus as
Hercostomus and, using the key for the females, as
H. exarticulatus. What do you believe? Below, I provide photos of the specimen, as well as the characters I used in the key:
1) Femora yellow.
2) Lower postocular setae light.
3) Antennae entirely black.
4) Fore tibia without median posteroventral seta.
5) Proboscis dark.
6) Wing veins R4+5 and M1+2 convergent, at least at apex.
7) Scutellum bare.
8) Metepimeron black.
9) Basal segment of antennal stylus not thickened at apex.

It is not
H. exarticulatus.
There is a recently described species with similar characters. Unfortunately, its female was poorly described.
Hercostomus thraciensis Kechev et Negrobov, 2015: Acta Zoologica Bulgarica 67 (2): 200. Type locality: Bulgaria: Basha site, northwest of the town of Chirpan, 148 m. Palaearctic: Bulgaria, Israel, Turkey.

Thanks a lot for the reply! Unfortunately, currently, we only have this one female. However, my colleague will try to collect more next spring!
