Dear friends,

from the same location, where I collected the Saropogon cf eucerus I caught 2 females of another species Asilidae. I think they are Neomochtherus, but with the help of the revision of Tsacas I do not come to a final conclusion, so your help is needed. Important is that the palp bears both whitish and black long hairs.

so, let me know what other photos you need. I do realize that the biggest problem is that I have only females.

I understand why you came to the conclusion Neomochtherus (shape of ovipositor)but the facial gibbosity is too big. I will have to look this one up...???

Maybe something like this: http://www.diptera.info/forum/viewthread.php?forum_id=2&thread_id=7391 also from crete but a male, legs similar.

Hello Reinoud,

I simply used the key to the genera in the contributions to a manual etc etc. So if I am wrong with the genus I am not even that surprised. Please, I am very interested in your opinion.

Reinoud, if I compare my two females with the males in the other diptera.info posting then I can imagine that they belong to the same species.
I have a description of Engelopogon, but it is in Russian, which I cannot understand. I'd rather follow a description than just comparing some photos, you know.
Further I only have the description of "Machimus brunnipes" in FdF, but for me that is certainly not definitive

It is going to be difficult a lot is still unknown about the species from southern Europe. Machimus brunnipes is Engelepogon brunnipes. This species has no black tripes on femora and the basic segments of the antennae should be yellow. According to Engel the species E. goedli and E. ravus seem to be good candidates. Especially the latter. Both species are known from Greece.

thanks a lot, Reinoud. I was aware of the brunnipes status, but the description in FdF was not definitive, that is not for me. I will check this evening E. goedli and E. ravus. I don't know whether I have the description,yet I have quite a lot of pdfs about robberflies.
I keep you informed.
