Arianops neglecta
Arianops neglecta is a species of rove beetle in the family Staphylinidae, subfamily Pselaphinae. It was described by Barr in 1974. The genus Arianops belongs to the tribe Amauropini within the diverse and species-rich pselaphine lineage. Members of this genus are small, cryptic beetles typically found in leaf litter and soil habitats. The specific epithet 'neglecta' suggests the species may have been overlooked or confused with related taxa prior to its formal description.
Batrisodes frontalis
Batrisodes frontalis is a species of ant-loving beetle in the family Staphylinidae, first described by LeConte in 1849. It is distributed across northern North America, with records from Canada and the northern United States. Like other members of its genus, it is associated with ant colonies, though specific ecological details remain poorly documented. The species is one of several in the genus Batrisodes found in North America.
Caccoplectus
Caccoplectus is a genus of myrmecophilous (ant-loving) rove beetles in the family Staphylinidae, subfamily Pselaphinae. The genus was established by Sharp in 1887 and contains approximately nine described species. These beetles are associated with ant colonies, a common ecological strategy among pselaphine beetles. Most species have been described from the Neotropical region, particularly Central America.

Ctenisis raffrayi is a species of rove beetle in the subfamily Pselaphinae, a group of small, often ant-associated beetles characterized by reduced elytra and compact bodies. The species was described by Casey in 1893 and belongs to the tribe Ctenistini. It occurs in southwestern North America and Central America. Like other pselaphines, it is likely associated with leaf litter and soil habitats, though specific ecological details remain poorly documented.
Euplectus confluens
Euplectus confluens is a small rove beetle (family Staphylinidae, subfamily Pselaphinae) described by John Lawrence LeConte in 1849. It belongs to the tribe Euplectini, a group of minute beetles typically found in leaf litter and soil habitats. The species has a broad distribution across eastern and central North America, with records extending from Canada to the southern United States. Like other pselaphine rove beetles, it is presumed to be a predator or scavenger in decomposing organic matter, though specific ecological details remain poorly documented.
Euplectus duryi
ant-loving beetle
Euplectus duryi is a small rove beetle in the family Staphylinidae, specifically within the subfamily Pselaphinae—a group commonly known as ant-loving beetles. The species was described by Thomas L. Casey in 1908. It occurs across much of North America, with records spanning from Canada (British Columbia to Quebec and the Maritimes) throughout the United States from the Atlantic seaboard west to Arizona and Colorado. Like other pselaphines, it is typically found in leaf litter and soil habitats where it associates with ant colonies.
Mipseltyrus nicolayi
Mipseltyrus nicolayi is a species of ant-loving beetle in the family Staphylinidae, described by Orlando Park in 1953. It belongs to the subfamily Pselaphinae, a group of small rove beetles commonly associated with ant colonies. The species is known from North America, with records from North Carolina and Tennessee.
Pselaptus
Pselaptus is a genus of minute rove beetles in the subfamily Pselaphinae, family Staphylinidae. Members of this genus are characterized by their small size and the compact body form typical of pselaphine beetles. The genus was established by John Lawrence LeConte in 1880. Like other pselaphines, species in this genus are presumed to inhabit leaf litter and soil microhabitats, though specific ecological details remain poorly documented.
Reichenbachia appendiculata
Reichenbachia appendiculata is a species of ant-loving beetle (myrmecophile) in the rove beetle family Staphylinidae. It is known from a limited number of observations across Central America and southern North America. The species belongs to the subfamily Pselaphinae, a group characterized by small size and complex ecological associations with ants and soil habitats. A nominotypical subspecies, R. appendiculata appendiculata, was described by Raffray in 1904.
Tychobythinus
Tychobythinus is a genus of small rove beetles in the subfamily Pselaphinae (Staphylinidae). The genus is widely distributed across the Palearctic region, including North Africa, southern and Central Europe, the Caucasus, Japan, far eastern Russia, and southeastern China. Several species exhibit troglobitic adaptations, including reduced pigmentation, microphthalmia, winglessness, and elongated appendages. The genus contains at least 44 species and subspecies in Italy alone, with ongoing taxonomic revisions clarifying species boundaries and synonymies.
