Trichophyinae C.G. Thomson 1858:

Trichophya pilicornis can be recognized by a combination of the characteristic antennae (Fig. 1.21.2), the heavily setose dorsal surface, body widest at elytra and the distinct neck (Fig. 1.22.1). This species resembles some Tachyporinae but possesses specialized antennae and strongly enlarged first and second antennomeres (Fig. 1.21.2).


This species also occurs in the Palearctic region and is suspected of being introduced into northeastern North America via human activity (Ashe and Newton 1993). It was first recorded in 1895 from New York and was known from Canada (Ontario) by 1905 (Ashe and Newton 1993). Unlike most other non-native Staphylinidae, it is very common in the boreal forest (Paquin and Duperre 2001) and apparently less common south of this ecozone. Trichophya pilicornis can be collected by sifting leaf litter (Fig. 9.21.1) or by pitfall trapping. Species of Trichophya are mycophagous and facultatively predaceous (Ashe and Newton 1993).
