Here are some images of a large dark tabanid taken on Lesbos recently. They seemed quite similar to me to the D. anthracinus I photographed in Corsica last year and had identified on this site: http://www.diptera.info/forum/viewthread.php?forum_id=5&thread_id=30716 but I'm pretty sure these Lesbos flies were smaller and on checking the photos closely, the antennae don't look as deeply notched and the wings are more patterned. The less notched antennae also rules out D. ater I think and they don't look dark enough for D. carbonaria from pics I've seen, so is this another Dasyrhamphis species that I can't find any images of, or is it another genus altogether, possibly Hybomitra? Hoping for help as usual.. 31.5.11 c 11mm Lesbos, Greece on umbels and mint near north coast.

Yes, Dasyrhamphis, the lack of notched antennae, partially dusted subcallus and clear (ish) wings leads to umbrinus Steve |

Many thanks Steve. The only possible image I can find of this is on this site: http://www.diptera.info/forum/viewthread.php?thread_id=18474 of a specimen photographed in croatia which Theo thought might be S. umbrinus, but there was only 1 shot to go on and no specimens. It is recorded from Greece and Turkey according to museum records http://data.gbif.org/datasets/resource/1458/datatracking/ so the location looks good too (Lesbos, though part of Greece, is just off the coast of Turkey). I really should post some of these shots in the gallery as I should for my D. anthracinus pics. I thought i had posted them but find I haven't. Must have run out of steam last time I was posting a big batch of shots!

Yes, it is umbrinus indeed. A Pontic species, so southeast Europe, Turkey, etc... Theo |

Many thanks Theo for again confirming Steve's ID. I will get on with posting these for the gallery as this species is not shown.
