Staphylinidae
Guides
Xantholinini
Xantholinini is a tribe of rove beetles (Coleoptera: Staphylinidae: Staphylininae) comprising approximately 141 genera with a cosmopolitan distribution across all zoogeographical regions. Members are small to medium-sized (2–20 mm), slender, short-winged beetles with elongated bodies and relatively short legs adapted for moving through narrow spaces. The tribe has been the subject of extensive taxonomic revision, particularly in the Eastern Mediterranean, Turkey, China, and the Neotropics, with numerous new species described in recent decades.
Xantholinus linearis
Linear Rove Beetle
Xantholinus linearis is a rove beetle in the family Staphylinidae, characterized by an elongated, slender body form typical of the genus. The species was described by Blatchley in 1910. As a member of the tribe Xantholinini, it belongs to a group of rove beetles often associated with decaying organic matter and soil habitats. The specific epithet 'linearis' refers to the linear, slender body shape.
Xantholinus longiventris
Long-bellied Rove Beetle
Xantholinus longiventris is a species of rove beetle in the family Staphylinidae, first described by Heer in 1839. It is known from the Azores archipelago, with records from five islands: Faial, Flores, Graciosa, Pico, and São Jorge. The species is recognized by iNaturalist as the Long-bellied Rove Beetle and has accumulated over 200 observations, suggesting it is relatively well-documented for an island endemic. Its taxonomic status shows some discrepancy between sources, with Catalogue of Life listing it as a synonym while GBIF treats it as accepted.
Xanthopygina
Xanthopygina is a subtribe of rove beetles (Staphylinidae) containing approximately 334 species distributed across the Neotropical region from the southern United States to Argentina. Species within this subtribe are frequently encountered in tropical forests and can be abundant in various microhabitats. The subtribe has been the subject of extensive taxonomic revision due to historically poorly defined genera, particularly the genus Gastrisus, which accumulated morphologically disparate species without clear diagnostic boundaries. Recent phylogenomic studies have resolved relationships within Xanthopygina, identifying nine major lineages and clarifying generic limits.
Xanthopygus
Xanthopygus is a genus of rove beetles (Staphylinidae: Staphylininae) established by Kraatz in 1857. The genus belongs to the subtribe Xanthopygina and is distributed across Mexico, Central America, the West Indies, and South America. A 2022 taxonomic revision by Chatzimanolis updated distributional records, resolved nomenclatural issues including synonymies and type designations, and provided an illustrated identification key for all species. The genus is characterized by distinctive morphological features typical of the Xanthopygina, though specific diagnostic traits vary among species.
Xanthopygus xanthopygus
Xanthopygus xanthopygus is a species of rove beetle (Staphylinidae) in the tribe Xanthopygina. Originally described as Staphylinus xanthopygus by Nordmann in 1837, the species has undergone taxonomic revision with a lectotype designated in 2021. The species occurs in the Americas from the southwestern United States through Central America to South America. As a member of the large rove beetle family, it belongs to a group characterized by shortened elytra and flexible abdomens.
Xenicopoda
Xenicopoda is a genus of rove beetles (family Staphylinidae) in the tribe Anthophagini. It is monotypic, containing only the single species Xenicopoda helenae, which is known from California. The genus was established by Moore and Legner in 1971.
Xenicopoda helenae
Xenicopoda helenae is a species of rove beetle (Staphylinidae) described from California in 1971. It belongs to the subfamily Omaliinae, a group of rove beetles often associated with decaying plant matter and fungal habitats. The species is known from limited collection records in California.
Xestolinus abdominalis
Xestolinus abdominalis is a rove beetle species in the family Staphylinidae, described by Thomas L. Casey in 1906. It belongs to the tribe Xantholinini within the subfamily Staphylininae. The species has a broad transcontinental distribution across northern North America, with records spanning from Alaska and western Canada to the northeastern United States and south to Arizona and Colorado. As with most rove beetles, it is likely associated with soil and decaying organic matter habitats, though specific ecological details remain poorly documented.
Zyras obliquus
Zyras obliquus is a species of rove beetle in the family Staphylinidae. It measures 4.0–6.5 mm in length and is distributed transcontinentally across North America from the northern United States to the southern half of Canada. Adults have been collected in both coniferous and deciduous forests. The species has been confused with the closely related Palearctic species Zyras haworthi.
