Well, I'm not sure if there are small bristles or not on the propleuron. The other big question is if Seguy 1934 keys are still useful for european Tetanocera. The other keys I found are not free download. And the last question is if genitalia is needed to get a species name. Edited by rafael_carbonell on 23-10-2022 19:04

For frons, better angle would be from front and a bit upward. Frons doesn't look shiny to Me, I'd bet on T ferruginea. You can exclude T hyallipennis anyway, costa is a bit darkned in this species.
