Arthrolips fasciata
Arthrolips fasciata is a minute beetle species in the family Corylophidae, originally described by Erichson in 1842. Records indicate presence in Belgium with some uncertainty, and the species has been observed 18 times on iNaturalist. Like other members of this family, it is among the smallest beetles, typically associated with decaying organic matter and fungal habitats. The genus Arthrolips is part of the diverse microbeetle fauna that remains understudied due to its diminutive size.
Cephennodes
Cephennodes is a genus of minute rove beetles in the subfamily Scydmaeninae, tribe Cephenniini. First recorded in South Africa in 2013 with four new species described from KwaZulu-Natal Province. The genus has a broader distribution across the continental Afrotropical region. Members of this genus are small, compact beetles adapted to microhabitats such as leaf litter and soil.
Cylindroselloides
Cylindroselloides is a genus of featherwing beetles (family Ptiliidae) established by Hall in 1999. It belongs to the tribe Nanosellini within the subfamily Ptiliinae. The genus is part of one of the most diverse families of Staphylinoidea, characterized by extremely small body size. As a recently described genus, it remains poorly known with limited published information available.
Gloeosoma hesperum
Gloeosoma hesperum is a minute beetle species in the family Corylophidae, a group commonly known as minute fungus beetles. First described by Casey in 1900, this species belongs to a genus characterized by extremely small body size and association with fungal substrates. The family Corylophidae is among the smallest beetles in North America, with most species measuring less than 2 mm in length. Records indicate presence in Nova Scotia, Canada, though detailed biological information remains sparse due to the cryptic habits and diminutive size of these insects.
Pedilophorini
Pedilophorini is a tribe of minute moss beetles (family Byrrhidae) established by Casey in 1912. Members are classified within the subfamily Byrrhinae and are characterized by small body size and association with mossy microhabitats. The tribe contains multiple genera distributed primarily in the Holarctic region. These beetles are part of the diverse Byrrhoidea superfamily within the Elateriformia infraorder.
Scydmaeninae
Ant-like Stone Beetles, Scydmaenines
Scydmaeninae is a subfamily of minute rove beetles (family Staphylinidae) containing approximately 4,500 species in about 80 genera. Formerly treated as a distinct family, they were reclassified as a subfamily in 2009. Members are commonly known as ant-like stone beetles due to their constricted body shape resembling ants. The subfamily has a worldwide distribution and is divided into four extant supertribes: Cephenniitae, Mastigitae, Scydmaenitae, and the extinct fossil supertribe Hapsomelitae.
