I photographed this Asilidaein Susa Valley, Piedmont (Italy) at 1700 mt above sea level, on 14th August 2016. Is it identifiable?

I think this may be a female Neoitamus castellanii

I realise that there is another option... Neomochtherus alpinus! Do you have a lateral picture, so we can see the ovipositor better?

Unfortunately I haven't got other photos... What are the differences between these two species?
Another question: Neomochtherus alpinus is the same species that on Systema Dipterorum is called Paritamus alpinus? And Neomochtherus melanopus is a synonym of this species?

One of the most clear differences is the shape of the genitalia, in Neoitamus the abdominal segments 1-5 or 6 are tomentose the rest are shiny black and part of the genitalia thus creating a long ovipositor for instance. In Neomochtherus all segments are tomentose. And....yes and yes...

Thank you very much! So what identification do you think is more probable? N. castellanii or N. alpinus? Maybe the distribution and the habitat is more fitting for the second one...

Yes, I tend now more to N. alpinus, also because of what is visible of the ovipositor..seems to be more fitting.

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol

Yes, dipterologists from far abroad, please buy your copy at veldshop. Stamps will be expensive, but he, the book is unreasonably cheap Smile
