Well, it is obviously a species from subgenus Saltrichocera. Visible features leaves me with a choice between brevis, pappi, rufulenta, sparsa or maybe some other species. You should check if there are any visible setae on pleurons and whether sternite IX has seatae or is deeply incised  Here is how the "normal" IX sternite looks in rufescens

And here is an incised sternite of Trichocera calva - you can see only two setae and a deep incision in the middle.

Do the hairs belong to sternits and tergites? Or are some on the pleura?

Well, I see I haven't expressed myself rightly Could you make a photo of the last sternite, as in my image of rufescens? Quite often it is covered by the 8th sternite, so you should push that 8th one a bit for the 9th to extend and be fully visible. Concerning the setosity on pleurons, it should be checked on thorax (mesothoraxic epimeron and metepisternum), not abdomen - sorry for not telling that earlier... |

Hi! I checked the specimen, will upload photos in the evening. The last sternite doesn't seem to be deeply incised and bares more hairs. I did not spot hairs on pleura. Should I make other photos still? I'm home now so I can make photos, but only today or next weekend. |

I'm sorry to tell, but I can't say for sure which species this is... I guess we can leave it as Trichocera cf. michali Krzeminska, 1999  |

Many thanks for Your valuable help! I guess I have at least one more month to collect Trichoceras So we'll see if I find any other species. Thanks again! |
