Abdiunguis
Abdiunguis is a genus of minute rove beetles (family Staphylinidae, subfamily Pselaphinae) established in 1962. As a member of the tribe Trichonychini, it belongs to a diverse group of small beetles that inhabit leaf litter and soil microhabitats. The genus contains species with reduced elytra and compact body forms characteristic of pselaphine beetles.
Allotrimium
Allotrimium is a genus of minute rove beetles in the family Staphylinidae, subfamily Pselaphinae, described by Orlando Park in 1943. It belongs to the tribe Trichonychini within the diverse and speciose Pselaphinae, a group characterized by reduced elytra and complex antennal structures. Members of this genus are small, cryptic beetles associated with leaf litter and soil habitats. No observations or species-level documentation are currently available in major biodiversity databases.
Byrrhinae
pill beetles
Byrrhinae is a subfamily of pill beetles within the family Byrrhidae, established by Latreille in 1804. The subfamily comprises approximately 25 genera and at least 160 described species. Members are small, compact beetles with a characteristic rounded, pill-like body form that enables conglobation—rolling into a ball when disturbed. Byrrhinae represents the more species-rich of the two subfamilies in Byrrhidae.
