Hello
Could this be gracilis?
Denmark 31.vii.2020
Partly yellow legs and that stribe of dust on katepisternum.
Front femur with the bigger "spike" and the two black shorter pointy ones and the large setea also visible.
I have keyed it using PontMeier
It looks ok here: https://sepsidnet.biodiversity.online/species/Sepsidae-000301-gracilis where they also list Denmark, but for some reason the species is not listed in our databases?!
I may very well have made a mistake.
Anyone?
Cheers :-) Rasmus

Hello Rasmus & helge,
Sepsidnet is very nice, but also very useful is the monograph of European Sepsidae, which is freely available online: https://www.resea.../263429542
As to the specimen I'm curious to know the circumstances of the capture. Could you tell more about it?
It is a very nice find and you should consider publishing the record somewhere. Quoting the aforementioned monograph: "Denmark: 1 specimen, without locality but maybe NEZ (Stæger)."
Kind regards,
Ectemnius

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol

Yes, dipterologists from far abroad, please buy your copy at veldshop. Stamps will be expensive, but he, the book is unreasonably cheap Smile
