The following photo's show a species of Dioctria who is sexually dimorph, like D. cothurnata. The key of Weinberg & Bachli aswell as Engel give no satisfactory answer. Like D. atricapillus the flies have, when alive, bright blue eyes. Christoophe posted a photo of a live specimen on the web: http://www.insecte.org/forum/viewtopic.php?f=11&t=50694 Has anyone any idea to which species? The features on the specimens make the species easy to identify within the genus. The specimens were caught: France: Alpes-Haute-Provence Moustiers-Sainte-Mairie 3-7-2012 Greetings, Ectemnius |

Seguy (faune de france, 1927) describes D. claripennis (only males, black legs) and D. wiedemanni (only females, yellow legs) from the region these Dioctria's come from. Is that the solution. Both are seen as valid species. If indeed claripennis and wiedemanni fit the specimens, the observation suggest is it one dimorphic species. |

That would be a funny story : ) The senior name would become the valid one i presume?

Engel didn't include them in key but does give descriptions : ) A bit short these descriptions but it might be theeee solution. Especially description of (male) D. claripennis fits really well. According to FE D. wiedemanni is known from Slovakia......wrong identification? (Not in key by Geller-Grimm indeed).

This Czech article mentions D. wiedemanni as occurring on the Pannonian steppes. Would be interesting to see specimens from that region. |

Thanks Mark, that is interesting, on FE the species is given for Slovakia (bordering on Moravia), we really need to check that if possible.
