Arpedium
Arpedium is a Holarctic genus of rove beetles (Staphylinidae: Omaliinae: Anthophagini) first described by Erichson in 1839. The genus comprises approximately 14 species distributed across the Nearctic and Palaearctic regions, including Europe, Japan, North America, and Central Asia. At least one species, A. cribratum, has been identified as a subnivium specialist—active beneath winter snowpack and rare or inactive during summer. The genus has undergone taxonomic revision, with five new species described recently and several synonymies resolved.
