This is a species in the genus Dalmannia of the family Conopidae! Although it looks a bit like Dalmannia punctata, it is different, also in the color of the abdomen. The fly was collected in Southern France in may. Anyone knows what species this might be?

Hi Gerard I agree it's Dalmannia, but not punctatum. Have you tried Seguy's key? I haven't got it here, but will check it next week and may be able to get a name then. Tony ---------- Tony Irwin |

Thanks Tony, No I haven't got Seguy's key here, maybe it would be a good idea to try to get his keys for Diptera, because I spent a lot of time in France! Hope to hear more from you, Greetings, Greetings, Gerard Pennards |

Hi Gerard I think it's safe to call this Dalmannia dorsalis. I don't know Dalmannia confusa, which appears to be known only from Croatia. It's certainly not D. punctata (a single row of central spots) or D. marginata (all black scutellum). There appears to be a bit of confusion* over dorsalis and aculeata, but it seems that aculeata has yellow front coxae and is larger (9 - 12 mm). D. dorsalis has black front coxae and is smaller (5 - 6 mm). On the basis of coxal colour, yours seems to be dorsalis. The size should confirm this. Apparently D. dorsalis occurs in Finland, so perhaps Kahis is familiar with this species and can tell us whether it looks like it!  * It appears that Seguy thought dorsalis was a synonym of aculeata, but his description of his other species (flavescens) fits dorsalis better, though it differs in a couple of points.

Thnx Tony, I had already found several species in the genus Dalmannia via the internet, but no link to a key or pictures. Now I can label them correctly. Thanks again, greetings Gerard Greetings, Gerard Pennards |

It has been collected only four times from Finland in the pre-war years. I think it may be extinct now. All records are from a small area in south-central Finland; a region known for its very early springs. The dry, open habitats in the region are practically all lost due to changes in field and forest management. Kahis |
