Wow, Reinoud, thanks again for naming all the flies!
The pictures are all from 2007 until now from the environment of Zeist. I didn't pay so much attention to them, as to me they all seem to be the same.
I'm very happy that I found you to be able to name so many and I'm collecting them now.

So, we may continue these first OK.
This fly is found 5-9-2009 in Zeist, Holland

Regards,
Hedy

I am not entirely sure, this could be Tolmerus (Machimus) cf atricapillus female. Maybe a dark legged cingulatus.

Hello Hedy,

I live in Brabant but i do have a nice hide out near Maarn....In Brabant I have never seen the Neomochtherus species and i am wondering why... I am interested in their habitat. As for Antipalus, i found them in Brabant only in the very sandy area of the Loonse en Drunense duinen sofar. But i do get the impression that this rare species is restricted to such areas where there is loads of sand , like dunes. So if you could remember anything about the habitat it would be welcome information. Keep up the good work B)

Maybe this might help identifying your critters: http://www.robberflies.info/keyger/start.html

As for the scientific names.. Internationally (Fauna Europaea) valid name for Paritamus is now Neomochtherus. A lot of the species of genus Machimus are placed in the genus of Tolmerus, in NL the "old" names are still used. I think the difference is based on the inside of genitalia. For the Netherlands that is the case with M. atricapillus, M. cingulatus and M. cowini, they have become Tolmerus.
