Anthophagini
Guides
Acidota
A genus of rove beetles (Staphylinidae: Omaliinae: Anthophagini) established in 1829. Species occur across the Holarctic region, with documented presence in Eurasia and North America. The genus includes at least 10 described species, with recent taxonomic work clarifying species boundaries and geographic distributions in Russia and China.
Amphichroum
Amphichroum is a genus of rove beetles (Staphylinidae) in the subfamily Omaliinae and tribe Anthophagini, established by Kraatz in 1857. The genus comprises approximately 32 described species distributed across montane regions of Asia, with significant diversity in the Himalayan region, Tibet, and southwestern China. Recent taxonomic revisions have added numerous species from China, particularly from Yunnan and Sichuan provinces. Species are primarily known from high-elevation mountain localities.
Amphichroum maculatum
Amphichroum maculatum is a species of rove beetle in the family Staphylinidae, subfamily Omaliinae. It is a small beetle found in western North America, with records from British Columbia south through Washington, Oregon, and California, and east to Nevada. The specific epithet "maculatum" (spotted) suggests a patterned appearance, though detailed morphological descriptions are limited in available sources. As a member of the Omaliinae, it likely inhabits moist terrestrial environments where these beetles are commonly encountered.
Arpedium
Arpedium is a Holarctic genus of rove beetles (Staphylinidae: Omaliinae: Anthophagini) first described by Erichson in 1839. The genus comprises approximately 14 species distributed across the Nearctic and Palaearctic regions, including Europe, Japan, North America, and Central Asia. At least one species, A. cribratum, has been identified as a subnivium specialist—active beneath winter snowpack and rare or inactive during summer. The genus has undergone taxonomic revision, with five new species described recently and several synonymies resolved.
Arpedium schwarzi
Arpedium schwarzi is a rove beetle (Staphylinidae: Omaliinae: Anthophagini) belonging to the Schwarzi species group within the genus Arpedium. It is an eastern North American species with a distribution spanning the eastern United States and southeastern Canada. The species was described by Fauvel in 1878 and has been subject to taxonomic revision, with lectotype designation and redescription in recent studies.
Artochia
Artochia is a genus of rove beetles (Staphylinidae) in the subfamily Omaliinae, tribe Anthophagini. The genus contains two described species: Artochia californica (California) and Artochia productifrons (distributed across British Columbia, Alaska, California, Oregon, Utah, and Washington). It is a small, rarely encountered genus with limited documented observations.
Brathinus varicornis
Brathinus varicornis is a species of rove beetle in the family Staphylinidae, subfamily Omaliinae. It was described by John Lawrence LeConte in 1852. The species occurs in northeastern North America, with records from Canada and the northeastern United States. Very few observations of this species have been documented, with only two records in iNaturalist as of the data cutoff.
Deinopteroloma
Deinopteroloma is a genus of rove beetles (Staphylinidae: Omaliinae: Anthophagini) established by Jansson in 1946. The genus was transferred from Silphidae to Staphylinidae based on morphological evidence and is now classified within the Anthobium group of genera. Species occur in the Pacific Northwest of North America, the Nepal Himalayas, northeastern Burma, China (Sichuan, Yunnan), and northern Vietnam. The genus includes at least nine described species, with several new species described from China and Vietnam in 2016.
Geodromicus plagiatus
Geodromicus plagiatus is a rove beetle (Staphylinidae: Omaliinae) first described by Fabricius in 1798. It belongs to the plagiatus species group, one of several species groups within the genus defined by male genitalia morphology. The species has a broad Palaearctic distribution and has been recently recorded from previously unreported regions including Albania, Cataluña (Spain), Moldova, Georgia, Uzbekistan, and extensive areas of Russia.
Microedus
Microedus is a genus of small rove beetles in the family Staphylinidae, subfamily Omaliinae, tribe Anthophagini. The genus was historically known only from North America but was expanded to the Palaearctic Region following taxonomic revision in 2022, which synonymized two Palaearctic genera (Altaiodromicus and Liophilydrodes) with Microedus. The genus currently contains 16 species: seven in the Nearctic Region and nine in the Palaearctic Region. Members of this genus belong to the Hygrogeus group of omaliine rove beetles.
Microedus austinianus
Nearctic rove beetle and type species of the genus Microedus. First illustration of mouthparts and aedeagus provided in 2022 taxonomic revision. One of seven Nearctic species in a genus now recognized as transcontinental.
Omalorphanus aenigma
Omalorphanus aenigma is a species of rove beetle in the family Staphylinidae, described by Campbell and Chandler in 1987. It belongs to the subfamily Omaliinae and tribe Anthophagini. The species is known from the Pacific Northwest region of the United States, with records from Oregon.
Orochares
Orochares is a genus of rove beetles (Staphylinidae: Omaliinae) established by Kraatz in 1857. The genus is classified within the tribe Anthophagini. One species, Orochares debilis Sharp, has been the subject of specific ecological study. Records indicate presence in northern Europe and northeastern North America.
Pelecomalium
Pelecomalium is a genus of ocellate rove beetles (family Staphylinidae) established by Casey in 1886. The genus belongs to the subfamily Omaliinae and tribe Anthophagini. At least three species have been described: P. laevicolle, P. puberulum, and P. testaceum. Members of this genus possess ocelli, a characteristic feature distinguishing them within the rove beetles.
Trigonodemus
Trigonodemus is a genus of rove beetles (Staphylinidae) in the subfamily Omaliinae, tribe Anthophagini. It was established by John Lawrence LeConte in 1863. The genus is rarely encountered, with minimal published documentation and few observational records.
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.
