Can someone help me with this fly? Found in a cave hibernating in the Viroin valley, in the southern part of Belgium. Jonas Mortelmans told me he first thought it was a member of the Heleomyza family, but I photographed the genitals and he now assures me it's something else.
Any ideas?

Heleomyzidae. Genus Heleomyza. I think H. captiosa. The photo`s are not detailed enough for me to be completely sure.

I think it is captiosa. If you want confirmation you can send it to me at the Natuurhistorisch Museum Maastricht.

not captiosa :@ The genus is Scoliocentra ! and the species name is: S. villosa. Andrzej

I am too lazy to go upstairs to look in the catalogue of Pal. Diptera. I can't imagine that many Scoliocentra species have been collected in Belgium. Do you have information about this, Andrzej.

BTW, I feel more or less reluctant to react on any thing concerning Heleomyzidae; your remarks feel like a sting of a needle ;)

Wow, so it means that it's quite a good species for Belgium? Thanks Andrzej!

Not many:-) From the genus Scoliocentra (excl. 2 species of Gymnomus) only 4 species. The S. villosa is the most common species in caves ! Andrzej

Well, Joachim, maybe a too fast reaction. Perhaps it says more about the number of dipterists collecting Heleomyzidae, than about the occurence of certain species ;)

Okay, thanks to everyone for the determination :-)

Checked the catalogue. It is not specially mentioned from Belgium, but given the area, I won't be surprised that it has been recorded already, since it is knows from Central Europe, Northern Europa and Western Europe including UK.

It is in the (outdated - 1991) checklist of Belgian Diptera, mentioned as being present in the collection of the Belgian Royal Natural History Museum.
