Very interesting species! I would say Sybistroma-Ludovicius complex. Edited by Stefan Naglis on 16-02-2011 14:54 |

I guess it is an undescribed species of Sybistroma

The second fly has plain antennae. Is it female and the first male? |

Dear Valter, First of all, thanks for the specimens that arrived today. I feel truly honoured. I have good and bad news: the bad news is that this species is not new to science, the good news is that it concerns a Sybistroma as indicated before, namely Sybistroma transcaucasicus Stackelberg 1941. As far as I know, the species has not been collected outside the Caucasus (holotype male). And the female has not yet been described, which is an option now. Thanks again. Cheers, Marc |

Sybistroma transcaucasica (Stackelberg, 1941) [Ludovicius] (Brooks, 2005: Zootaxa 857: 114 [transcaucasicus]) * =Ludovicius transcaucasicus Stackelberg, 1941: in Lindner, Flieg.palaearkt.Reg. 4 (5): 200 ** Type locality: Russia: "Suchum, Transkaukasien" [= Sukhumi]. Palaearctic: Abkhazia, S Russia (Adygea, Krasnodar), Turkey * Sybistroma Sybistroma portugalica is certainly new for science. Compare antennae of the 2 species. I hope another specialist will describe it with great pleasure. Igor Grichanov attached the following image:  [66.41Kb] Edited by Igor Grichanov on 02-03-2011 11:49 Igor Grichanov |

Does it have special role in its biology? Thanks
