Is it possible to say anything more about this female Trichocera spec.?
It was collected by means of a pitfall trap (1-8.iv.2010) in Tilburg (the Netherlands).

Well, Trichocera females are tricky as are, well, most of women too :D
I see two possibilities here - it is either T. regelationis or T. hiemalis. Preparation of inner genitalic structures would help to say for sure. You could also check the tarsal claws - regelationis has the claws longer than half of the last tarsomere while claws of hiemalis make up to around 1/3 of the last tarsomere ;)

Thanks a lot Andrius! Given the length of the claws it must be a female of T. hiemalis.
