Is it possible to tell which genus this 10 mm fly belongs? Photos from 20 September 2014 Norasundet 62 N, E 17 Ã…ngermanland, Sweden. Thanks for your help in advance Regards Kurt Holmqvist kurt attached the following image: [109.31Kb] |

It looks to be Orthocladiinae, of which there are several genera with bifid gonocoxites, but I can't place this one with the literature I have available.

As far as I can tell no genus of Orthocladiinae in Sweden has the combination: Gonostylus with long, thin forks of the Brillia type. Eyes with short, wedge-shaped dorsomedial extension (long in most genera with similar gonostylus). R-m short, at about 45 degree angle to wing axis. No long volsellae as in Diplocladius, only a small lobe. Distinct anal point. Edited by John Carr on 22-09-2014 22:01 |

I think John's saying it would be good to see a specimen!
