Hi, is an ID possible? Found on polypore mushroom in a forest in Vienna. 5 mm long

Wing venation like Dynatosoma sp. but I don't know any Dynatosoma species with red abdomen.

Thanks Esko,
I couldn't find a match in the Gallery. Any key of this family available?

Bringing this up again, as I am really interested into getting ID help here

Key to the family is here: http://sciaroidea...node/22756. Literature references are given for most genera.

Thanks, John!
That's what I was looking for, and the key leeds indeed to Dynatosoma, as Esko suggested. I think it is a female, so I don't know whether the species can be IDes, but if there are few members with such a red abdomen, maybe it is possible nevertheless?

Can you check if the hind tibiae have only two rows of long setae (rather than three)? If not, then rufescens is most likely (what's in a name?).

Hey Paul,
rather three rows I'd say:

Yup, so rufescens it is.
