Hi, I'm located in Vancouver, Canada and have come across some Lonchoptera specimens which don't seem to match any of the North American species. John Klymko, who revised the nearctic species, suspects it may be a Eurasian species but is not familiar with the those species. Using Beuk's Key to European Species (https://www.onlin...?key_no=27) it keys to L. lutea.
If anyone has any experience identifying this group your input would be greatly appreciated.

Hi,
some of the following characteristics we can see and leads to lutea.
-Chaetotaxy of fore and mid coxa
-Chaetotaxy of fore and mid femur
-Chaetotaxy of fore and mid tibia (posterior side missing, in both there are important characters)

A picture of the Hypopygium would probably be the safest and easiest way to reach species level. Especially in view of circumstances of the find, this should definitely be checked by an expert.

here are some good pictures of lutea

I see nothing to suggest it would not be Lonchoptera lutea

I can no longer send private messages (and maybe not receive?), even though my inbox and outbox are not yet full. I write, click "send" and they disappear and never show up in the outbox.
