28 September 2008, Naro-Fominsk, Moscow region, Russia. I repeatedly come to Catocha latipes but it's obviously not the case, at least wing looks quite different in Yukawa (1971), so I took a wrong turn somewhere... Subject changed from Cecidomyiidae, Lestremiinae to Sciaridae, Zygoneura.

Hi Black, no doubt: this is a species of Zygoneura (Diptera: Sciaridae). Their antennae resembling that of gall midges and their apical spurs of tibiae are very short, but have a closer look on the wing veins and complexity of genital.... cheers, xylo |

Most characteristic for Zygoneura: bell-shaped fork in vein M. You can even see it in the top picture.

Looking at the genitalia preparations, it is clear that the first is Zygoneura sciarina. The second, however, is not a Zygoneura: it looks much more like a Xylosciara. Check the venation character mentioned above. |

Well, a detailed view of ventral inner margin of gonocoxites (base and apical end) would be interesting: there should be a group of more prominent setae. The excavation of apical fourth/third of stylus supports Zygoneura. And there are some more species described by Mamaev and Mohrig exclusively from Russia..... Let's wait what Black will report (Hopefully it is on one slide/in one vial).... so long, xylo |
