Hi everyone !!! On 2024-04-30 I could picture the specimen below. I could measure it on pictures : 9,3mm Using the Tschorsnig key for Tachinidae I think it could be a Macquartia ??? and going down in the key, I found : Tergite 2 not hollowed out to the posterior edge (as in figs. 167, 169). 3 dc behind the suture (in some females of praefica 4 dc, then the first dc is very short). Palps yellow to black > 3 Middle tibia with 2 - 5 ad. Tergite 3 with 2 - 4 dorsal marginal bristles > 5 Cheeks at most hairy in their upper half. Legs black > 7 Inner edge of the calyptrae lying close to the thorax (fig. 117). Frons in males as wide as 1/3 - 2/3 of the 3rd antennal segment > 8 Hind tibia with 3 dorsal apical spurs, the central one sometimes very short. Tergite 2 as a rule with 2 dorsal marginal bristles. Females: abdomen shiny black, with only very light dusting >>> Macquartia tenebricosa Meig. Here are some pictures :     Added 2024-05-02 this picture of the left wing :  As I can see , a light on the hind tibia can also help identifying ...  I also add this one with orange palps ...  Seeing the larger of the front, I think it could be a female … Is it possible that this could be Macquartia tenebricosa (Meigen, 1824) ??? Thank for comments and/or ID !!!! Have a good day, Didier Edited by Tetrao on 02-05-2024 08:44 |

Thank you very much, Theo ! I had a last question ! I didn’t found a drawing or a picture where I could see or determine the Pteropleural bristle at couplet 70 of the Tschorsnig key for Tachinidae ! Do you have a link to such drawing ? Didier |
