Hello, I’m submitting this male Thereva specimen for your opinions. I’m aware that identifying males in this genus is notoriously tricky, but following the key I used (not the one by Mark van Veen, which unfortunately seems no longer accessible), I was able to observe the listed characters that lead me to Thereva inornata: 2b. Anterior part of tergites 2–5 dark 4b. At least part of the tergites matte 5a. At least one posteroventral seta at the base of the hind femur 6a. Two pairs of dorsocentral setae -> Thereva inornata  JC Bartolucci : France : Saint-Laurent-d'Aigouze : 30220 : 17/05/2025 Altitude : NR - Taille : 12 mm Réf. : 359537  JC Bartolucci : France : Saint-Laurent-d'Aigouze : 30220 : 17/05/2025 Altitude : NR - Taille : 12 mm Réf. : 359540  JC Bartolucci : France : Saint-Laurent-d'Aigouze : 30220 : 17/05/2025 Altitude : NR - Taille : 12 mm Réf. : 359541 Despite these matching features, I still have some doubts — particularly due to the dark wing zones, which don’t quite match the gallery images I’ve seen for T. inornata. Any thoughts or confirmation would be greatly appreciated  Thanks in advance! JC Edited by JC_Bartolucci on 31-05-2025 20:23 |
