I cannot identify this damaged specimen of Dioctria from Prague. Darkened wing and golden stripes of pale tomentum on pleura are well visible. Body length 12 mm.

What a pity.....This might well be Dioctria flavipennis male. One thing doesn't fit.....dark hind tibia. And the golden dusting of frons is missing. I can't find another species with such an antennal hump and darkened wings.

Considering the shape of the specimen I think that Dioctria sp. male can be a fair ID. ;)

Thanks, Reinoud! I was thinking about flavipennis too, but blackish tibiae and golden tomentum (silver in flavipennis) + small redish markings on terga went also to bicincta. I am really confused...

Valerio is right Dioctria sp. But we can exclude bicincta, that species has hardly an antennal hump and the metatarsi of hind legs are very swollen.
