This anthomyiid was caught in a pitfall trap on a seashore. Is it possible to identify it?

The haired notopleuron area , short prealar, hair like acrostichals, katepisternal setae and a view on the gena and parafacial are the main visible characters.
The legs chaetotaxy is mainly hidden or to blur to see.
If the proboscis is shining black…maybe we could consider a Zaphne species, if not maybe one of the Delia radicum section.

Do you have hairy Eutrichota in Europe, ex-Eremomyia and Eremomyiodes?

Eutrichota has no interfrontals (if so, than very short and hair like) and the notopleuron area is never haired.
(but if you know an American Eutrichota, wich has....just let me know)
In my opion we can exclude Eutrichota in this case.

I looked for interfrontals but somehow missed them. They are also absent in all American Eutrichota.

Several American Eutrichota have hairy notopleuron.

Thanks for your help! The proboscis is shining black as you can see on the attached photo. I find it difficult to take good photos of the bristles on the legs, but if you tell what to look for maybe I can check the specimen under the microscope.

I have doubt if the proboscis is whole black shining, there seems to be some greyish dust in the middle.
When I am really honest, I think this will become a mission impossible to get a proper ID only based on photos.
So…if you really need an ID for this fly, you may send it to me. (but even then I can’t give any garanties because it’s a female)
If not, just save it…. and try next time to collect a male specimen, so we can check the genitals.

Sorry for my late reply. I will try to find a male fly in the summer.

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
