If you'd checked the forum archive, you'd have found that many Thecophora requests remained unanswered... It is a very tricky genus, and the experts agree that only females can be identified from photos by the shape of their genitalia. So your male hardly has a chance. This said, the key https://home.hccn...phora.html offers a small chance to approach the males, if there is a good view of the top of the thorax (two grey dust stripes flanking a middle black stripe or two black stripes in a grey field of dust). Sorry, but I cannot decide which to choose. So I followed both paths and got to T. distincta on the one hand and T. atra on the other, which brings us back to the starting point  If this is T. distincta: https://diptera.i...;pid=75178 or https://diptera.i...pid=311780, it looks a bit different as to the dusting. On the other hand, the pictures of T. atra males in https://www.flick...219920050/ look rather similar. So you could label your picture "T. cf. atra", but keep in mind that a mere comparison of pictures is no certain identification at all! Regards, Sundew |
