Quoting a key by Saether:
* Mid and hind tibia each with 2 spurs; tarsal claws with small, simple basal tooth; katepisternum III with numerous setae ...
Cryophila lapponica
* Tibia without spurs, tarsal claws with large median spine and serrated basal tooth, katepisternum with 0-8 setae ...
Mochlonyx
I think you have a
Mochlonyx. The third genus in your area,
Chaoborus, has longer first tarsomeres.
