Dear forum.
I photographed several specimens of an asilid in April on Rhodes, which I thing is Antiphrisson trifarius. To my surprise, I found an Antifrisson sp. again in October
on the same island. The latter, however, looks different to me. In general, the body color of the October specimens is lighter (more yellowish than brown), bristles around the periphery of the notum and the scutellars are whiteish (instead of black), there are no black bristles on the occiput and in the mystax. I think I see a subtle difference in the shape of the ovipositor of the two as well: T8 is slightly domed dorsally in A. trifarius, whereas in the "autumn" specimens the dorsal outline of it is essentially straight. But this could be an illusion caused by looking at it in different angles.

The "autumn" specimens resemble the few images of Antiphrisson adpressus found in the Internet, which is known from nearby Turkey. Could the "autumn" sp. be identical with A. adpressus?

Thanks for any help/comment in advance!

Greetings,
Henrik
