Hello,
Last month I caught this specimen in Limburg, the Netherlands. In a limestonequarry.
What species is this? We are confused by the key of Czerny, what should be the wimpern?
Kinds regards

Quoting Czerny's description of
H. breviciliata:
"Randborsten der Flügel äußerst kurz, unter den ebenfalls kurzen Wimpern ganz ver schwindend."
I believe Randbosrsten (Flügelrandborsten) are the bristles on the costa typical of Heleomyzidae, while Wimpern in the context of a wing are the small hairs found on the costa of many flies.

Hello John,
Thanks for your reply. Then it should be serrata. Does anyone know if there is a difference in genitalia? Or is that not known or is there no difference?
