Another member of the Azeliini? And therefore, given known options in Iceland...likely Thricops? ( Presuming not Anthomyiidae based on John Carr's comments here https://diptera.i..._id=114011 : "There are 4 pairs of postsutural dorsocentrals. The very few Anthomyiidae with 4 pairs are very hairy. There is only one dorsal or posterodorsal bristle on the hind tibia. Very few Anthomyiidae have this character." Not sure how to rule out Spilogona (?) But the three species of Thricops known to exist here are: Thricops cunctans (Meigen, 1826) Thricops longipes (Zetterstedt, 1845) Thricops rostratus (Meade, 1882) If Thricops, not rostratus given lack of protruding chin. Perhaps T.cunctans or T.longipes? sbushes attached the following image:  [149.36Kb] Edited by sbushes on 15-09-2024 05:54 |

Spilogona does not have a calcar, a strong posterodorsal bristle in the distal half of the hind tibia. The bristle is also called the "Phaonia bristle" because it is found in members of genus Phaonia. |

Ok nice. So, you agree this one should also be Thricops in theory? |

Mostly your list of 3 species. 1. It isn't rostratus or cunctans. 2. There are several secondary characters which fit well longipes. Nikita Vikhrev - Zool Museum of Moscow University |
