Have you got a photo of the fore tarsus and an overall shot of the whole fly?

To me the facial bristles rise too high for a Phryxe. If it is a Phryxe, I'm afraid it will be impossible to determine with certainty (a female). As it has black palps, it can be Nilea rufiscutellaris, however then it should have 4st. |

dear Jaakko, it has indeed 4st, but you can see two reclinate orbitals on the head, while middle tibia has at least five anterodorsals, that is why it cannot be Nilea and there are broken discals on the abdominal tergites. My guess about P. erythrostoma is based on narrow parafacialia and short VI costal section.

Let me start with a simple question; the scutellar apical don't seem to be erect, do they ? Theo |

dear Theo, apicals are either not erect, or they are broken, that happens..

Ah, that explains why I don't see them. In my experience, I prefer to ID erythrostoma on males. The females are more bristly on tergites in general, the outer orbital seta tends to be stronger than in outer Phryxe and yes, the wing venation definitely suggests erythrostoma. So you are likely to be right, but I am not the one to confirm it for 100 % Theo |
