From just this image I cannot tell. Posterior view of the genitalia, picture of mesonotum (showing number of rows of acrostichal setae) and an anterior view of the entire hind leg might help.

Isn't it Rhamphomyia subcinerascens?

Hi Niels-Jan,
No i do not think it is
R. subcinerascens, for two reasons:
1. The posterior bristles on the middle tibia have a different length as the anterior bristles.
2. The females i have collected at the same place do not show the "clouded" wing characteristic of
R. subcinerascens and seem to key out to
R. sulcatella as well.
Problem with the keys however are things as "longer" or "more conspicuous", which are a bit difficult to interpretate when one has not enough specimens to compare...

Bringing it to attention one more time...

With some reservations, as it is always better to see the actual specimen, this would come out as
R. cinerascens.

Thanks again Paul.
To remove all reservations, is it oke if i sent you a male and a female for a definitive identification?

As stated in an earlier Private Message, three species can occur at the same place at the same time in the Netherlands. To confirm this (at least in part), the male you sent is
R. cinerascens, the female is
R. sulcatella. I am certain there will be some [i[sulcata[/i] nearby as well. :D

Thanks Paul that explains some of the difficulties i encountered while trying to name them.
I wil carefully examine the other specima i have collected and see id
R. sulcata is around as wel.
