Trichophyinae
Thomson, C. G., 1858
Genus Guides
1Trichophyinae is a of rove beetles (Staphylinidae) containing only the Trichophya. Established by Thomson in 1858, this subfamily represents one of the most -poor lineages within the hyperdiverse rove beetle . The genus Trichophya contains multiple described species, though the exact number remains uncertain due to taxonomic revisions. These beetles are rarely encountered and poorly represented in collections.

Identification
Members of Trichophyinae can be distinguished from other staphylinid by their placement within the Trichophya. Diagnostic features for the genus include: short exposing most of the (as in all Staphylinidae), , and a characteristic body form with the narrower than the pronotum. The subfamily lacks the specialized morphological adaptations seen in many other staphylinid lineages such as the heavily modified mouthparts of Steninae or the compact form of Pselaphinae.

Distribution
of Trichophya have been recorded from the Holarctic region, with occurrences in Europe and North America. Records are sparse and scattered, reflecting both genuine rarity and undercollecting.

Taxonomic Status
The Trichophyinae has been historically unstable in classification. Some treatments have synonymized it with other subfamilies or treated Trichophya as incertae sedis within Staphylinidae. Current molecular and morphological evidence supports its recognition as a distinct subfamily, though its phylogenetic position within the remains poorly resolved.
Collection Rarity
With only 10 observations on iNaturalist and sparse museum records, Trichophyinae is among the least documented staphylinid . This rarity may reflect genuine low abundance, cryptic habits, or association with under-sampled microhabitats.
