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. Libor libor attached the following image:  [174.84Kb] |

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... Libor |

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.
