Achalcus cinereus is better.

That's why I put the '?' in

First suggestion was 'good', second suggestion was 'better', the final result is best''. After examination of the genitalia:
A. thalhammeri (new for the Dutch list).

That's interesting news Paul! Nice. Thanks!
I submitted a photo of this fly to the gallery as Achalcus cinereus (latest photo addition). It must be changed now to A. thalhammeri

Okay. If you then correct female to male on Waarneming.nl we are all up to speed.

Check the key to Achalcus in Pollet (1996): this is certainly not A. cinereus, but might, indeed, be A. thalhammeri due to its unicolorous thorax. However, you can only achieve 100% certainty by collecting the specimen and compare it to reference collection material.

Marc, the only way I could identify it a
thalhammeri was because I had the actual specimen.

Dear Paul,
Great to hear this. Is this observation to be found in waarneming.nl? Then I could include it, together with the collectors and identifiers, in an upcoming paper on new doli species for the Netherlands? Any chance you might get a male as well, you reckon? Cheers, Marc

Hi Marc,
At the moment I am writing a small article about this new (male) doli species. I found it in my garden last year.
