Thank you Reinoud!

Indeed, this is a small specimen, I estimated its size arround 15-16mm, but it is still within the range given for this sp., I think.

I can't say much about the alar bristles, so I attach enlargements of the thorax in the hope that they can help.

(In any case, I can't really see any possile ID other than M. arthriticus.)

Best regards,

Henrik
