Hi Krister Do you have some in focus images of the legs, particularly the hind ones? Those would help as would knowing whether Rs was forked or not. Steve Edited by Steve Scholnick on 07-02-2023 18:06 |

Hi Krister, You're welcome. I think the lack of setae on the tibiae suggests that your fly belongs in subfamily Metopininae rather than Phorinae. Rs is forked (links to some diagrams from Drawwing below) RS not forked (=R4+5 present but not R2+3) http://www.drawwi...icera-wing RS forked (=both R2+3 and R4+5 present) http://www.drawwi...nipes-wing Another feature that might help someone more knowledgeable than me get you a genus ID would be the presence or absence of a "hair seam" on the hind tibiae. There might be a hair seam on your specimen but I can't really tell from your photo Triphleba: no hair seam https://bugguide....ew/2213688 Stichillus: two dorsal hair seams on each hind tibia https://bugguide....ew/1618327/ With luck, one of the experts will be able to take this further Steve |

Genitalia resemble those of Triphleba trinervis (slightly turned when compared to the illustration in Disney's handbook). In that case there should be two pairs of strong setae on the scutellum (rather than an apical pair of strong setae and a lateral pair of hairs).

The apical pairs of setae are very strong and the lateral pairs are about half as long but still strong as setae (and not slender hairs). I will see if I can make a photo of them - but not easy with these small flies. Krister |
