Hi all,
I have some difficulties in ID'ing this remarkable fly, swept from marram grass dunes in the Netherlands.

- The head has very few hairs/spines. Only some very small, pale spines bordering the ocellar triangle, a small pale pair of converging post-ocellars and a small pair of pail outer vertical bristles, pointed backwards.
- The scutum has small pale hairs, regullarly all over, except 2 longer dorsoventrals just before the scutellum and 2 notopleural longer bristles, all pale.
- There is a vague pattern on the scutum (not or barely visible on the pictures) with 3 darker stripes, merged together to a total darker scutum before the suture (except from paler postpronoum & notopleuron).
- Scutellum has a converging apical pair of bristles
- A remarkable broadened last tarsal segment on leg 1

Any opinions welcome!
Thanks!
