I have no idea for this, and I hope this fly turns out to represent a new family for me.

Periscelidae jumped into my mind whenI first saw this. If not that, then perhaps Phortica (Drosophilidae)? (But now I'm struggling!  )

It would help to have the size. Roughly: < 3 mm: Periscelididae; > 3 mm: Phortica would be an option. Based on the legs I would rather discount Periscelididae.

Guess what, around 3 mm. It was a small fly. Too small compared to the Phortica sp photographed by me in Japan last year, which was a large Drosophilid. Also this fly did not try to land in my eyes and ears like the Japanese species, which was kind of superannoying. But the Phortica image from Japan indeed looks quite similar to the one in this thread, note the pale ring around the eye and the pale spots on the side of the thorax. What would be the major difference between the two families? |

The difference is primarily on wing venation and head bristles. Drosophilids have the costa broken twice, while periscelids have an unbroken costa. Drosophilids have convergent postverticals, while periscelids have divergent postverticals. Although it's not entirely clear, it looks like your fly has a twice-broken costa, so I withdraw the periscellid suggestion and will back Phortica. The two Hungarian species are very similar - I wouldn't like to call between them on the basis of this shot... Well, variegata if I had to choose one! Tony ---------- Tony Irwin |

Since I was searching for more information on the genus Phortica I contacted Dr. Jan Maca and also asked him to look at the pictures of the Phortica specimens on www.diptera.info. His comment on this specimen was: Dr. Jan Maca wrote: Probably P. variegata but difficult to see in this picture. Jan Willem |
