Proteinus basalis
Proteinus basalis is a species of rove beetle in the family Staphylinidae, first described by Mäklin in 1852. It belongs to the subfamily Proteininae, a group of small staphylinids often associated with decaying organic matter. The species has been recorded across western North America from Alaska to California, with additional records in western Canada. Like other members of its genus, it is likely associated with moist, decaying substrates where it feeds on fungal spores and small invertebrates.
Quedius marginalis
Quedius marginalis is a species of rove beetle in the family Staphylinidae, first described by Mäklin in 1852. It is currently classified as an ambiguous synonym in the Catalogue of Life, placed within the subgenus Quedius (Distichalius). The species belongs to the diverse genus Quedius, one of the largest genera in Staphylinidae, whose members are predominantly predatory and commonly found in soil, leaf litter, and decaying organic matter.
Sonoma parviceps
Sonoma parviceps is a small rove beetle in the family Staphylinidae, specifically within the ant-loving beetle subfamily Pselaphinae. The species was first described by Mäklin in 1852 under the name Euplectus parviceps. It is distributed across western North America, with records from Alaska through British Columbia and south to California. As a member of Pselaphinae, it is presumed to be associated with ant colonies, though specific ecological details remain poorly documented.
