Hello everybody!

This supposed Asilidae resembles Neoitamus cyanurus. But the red color of the apex is surprising. Even if it was illuminated by outside light, there was not a strong sun, and the photo on the right of the montage was taken with a flash, 3 or 4 cm from the beast.

Not Neoitamus, but rather Neomochtherus/Aneomochtherus or related

Thanks you Chris ! Smile

A colleague thinks of the genus Cerdistus. What do you think of this proposal?

Cerdistus is related to Neomochtherus and allies, so that is possible. I'm not entirely sure how to separate those genera to be honest.

Thanks Chris! Smile
It's a bit the same answer that my colleague gave me, asking for the genitalia to study them. But I did not capture the beast.

It is a Cerdistus cf erythrurus. The separation of Cerdistus is rather artificial but mostly they are small and have more DC than Aneomochtherus or Neomochtherus. Antennae always black. Somehow the separation feels "good" :-) At least I recognise them easily....
