1. I meaned Eu. strictica. 2. But it isn't E. strictica. I'm 95% sure it is Euthycera stricticaria, much less known species! Nikita Vikhrev - Zool Museum of Moscow University |

Yes Louis, misspeling, thank you. But correct is: Euthycera sticticaria (Mayer 1953) East Mediterranian species with long antennae 2-d. Nikita Nikita Vikhrev - Zool Museum of Moscow University |

Hello Nikita, I think your first idea, ie E. stictica is the correct ID for these reasons : - lunule and frontal vitta well marked ; - 3d antennal segment about the same length as 2nd and not so rounded (as in E. sticticaria). It's just my opinion, I can be wrong... Regards. Stephane. |

Stephane, May be, may be not. Looking at collected flies it seems to me that antennae is for sticticaria. But of course, it requires to compare with real E. stictica. In Moscow Zool museum there are several specimens of stictica with det. label of R.Rozko?n?, so it is a matter of short time and next week I'll write real ID with help of 6-th sternite  So, a bien tot!

Well , at my opinion, situation in Euthycera genus isn?t satisfactory (as well as in Sciomyzidae family, I think). 1. Euthycera stictica-sticticaria According Vala: E.stictica - very small face spot and antII = antIII E.sticticaria ? ?normal? face spot and antII > antIII According Rozkosny, on the contrary: E.stictica ? ?normal? face spot and antII > antIII E.sticticaria - very small face spot and antII = antIII According Rivosecchi: E.stictica ? small spot of anterior orbital seta (in text ? ?ventral? or seta(?)) E.sticticaria - big spot of anterior orbital seta Illustrations of genitalia looks also different to use practicaly. According Vala most ID of E.stictica-group are doubtfull, material is always fragmental and nobody can realy compare it. Material in Mosc Zool Museum determinated by Dr. Rozkosny (as usualy without other material to compare with) as E.stictica consists of 2 spp from North Caucasus and 8 spp collected by Andrey Ozerov in Middle Asia. Serias of 2 spp corresponds with my serias (of 19 spp), Middle Asian spp looks rather different. 2. So, I think that the best possible ID is so far Euthycera cf. stictica, as Stephane proposed. At least lunule is large... Nikita Vikhrev attached the following image:  [96.89Kb] Nikita Vikhrev - Zool Museum of Moscow University |

Thanks a lot Nikita for this synthesis. It seems indeed to be a complex group like there are in others families. Regards, Stephane. |

"It seems indeed to be a complex group like there are in others families"... ... or one old good Fabricius's species divided into several doubtful species without sufficient reasons
