Zosimova Pustyn station, Naro-Fominsk district, Moscow region, Russia. Just 20 m from the railroad, small forest (mostly Tilia cordata). Size around 2.8 mm. The only decent picture.

Hi Dima, Looks like Diastata costata to me, but that's without use of any key whatsoever, so not very trustworthy  .!!! Great pictures again !!! Jan Willem Edited by Jan Willem on 01-10-2007 11:48 |

Many thanks Jan Willem. I've come to D. vagans in Stackelberg's key but was lost in synonymy then... |

Diastata vagans should have cross-vein dm-cu strongly infuscated, which seems not to be the case in your specimen. So I still go for D. costata. Jan Willem |
