Using Tschorsnig this specimens runs to couplet 252 Besseria but does not seem to be this genus. Any suggestions appreciated

Hmm, it does look like a Besseria or Clairvillia - what makes you think it is wrong?

Clairvillia male. Hopefully this helps to find out what went wrong. Theo |

Many thanks Chris and Theo. I suspect my specimen failed at couplet 243 because my specimen shows a very short r5 petiole. taking the second option it runs easily to Clairvilla. There seem to be only 2 European species of which only Clairvillia pninae is recorded from Mallorca. This tread http://www.dipter...pid=101721 suggests pinnae has cell r4+5 cell closed at the border of the wing and yellow palpus (but it is female being discussed). Are these features good for male, any other way to separate them? |

The colouration of the palpi works in both sexes, though not always clear. In the male, hairs on tergites are adpressed in biguttata and erect in pninae. Both features indicate pninae in this case. Theo |

Actually, I messed up: it is vice versa. Theo |
