In my recent correspondence with Jindřich Roh?ček he could not decide whether the bottom fly is a
Spelobia sp. or
Opacifrons coxata, some important details are not visible clearly enough. Concerning the top fly (a different species), he writes that it
apparently belongs to Rachispoda and I believe it is one of the Rachispoda anceps (Stenhammar, 1855)-complex. Unfortunately, there are several very similar species recognizable only from genitalia combined with mid tibia & basitarsus chaetotaxy.
