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?
Best wishes, Niels-Jan Dek |

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... Greetings, Jan |

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

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.
