Aleocharinae
Guides
Tachyusa
Tachyusa is a genus of rove beetles in the family Staphylinidae, tribe Tachyusini. The genus was established by Erichson in 1837 and contains more than 20 described species. Members of this genus are small beetles with the characteristic short elytra of rove beetles. The genus is recorded from parts of northern Europe.
Tarphiota fucicola
Tarphiota fucicola is a small rove beetle (Staphylinidae) in the subfamily Aleocharinae. The species is restricted to coastal marine environments in the North Pacific. It was originally described as Tachyusa fucicola by Mäklin in 1852. The specific epithet 'fucicola' refers to association with Fucus, a genus of brown algae.
Thamiaraea
Thamiaraea is a genus of rove beetles (Staphylinidae) established by Carl Gustaf Thomson in 1858. It belongs to the subfamily Aleocharinae, one of the largest and most diverse groups within the family. The genus has a cosmopolitan distribution, with records from Europe including Denmark, Norway, and Sweden. Two species are documented: Thamiaraea hospita (Märkel, 1844) and Thamiaraea tsitsilasi Pace.
Thecturota
Thecturota is a genus of rove beetles in the family Staphylinidae, subfamily Aleocharinae, and tribe Homalotini. The genus was established by Casey in 1893. Species are recorded from Europe and North America, with specific documentation from Denmark, Norway, and Sweden. The genus includes at least two described species: Thecturota capito Casey, 1893 (the type species) and Thecturota antillarum Pace, 1987.
Thecturota capito
Thecturota capito is a species of rove beetle in the family Staphylinidae, subfamily Aleocharinae. It was described by Casey in 1893. This small beetle belongs to the tribe Homalotini, a group characterized by compact body forms and association with decaying organic matter. The species has been recorded in limited numbers across parts of North America.
Thiasophila
Thiasophila is a genus of myrmecophilous rove beetles (Staphylinidae: Aleocharinae) that inhabit ant colonies, primarily those of the Formica rufa species group. Species in this genus have evolved specialized adaptations for living among ants, including defensive secretions and morphological plasticity in immature stages. The genus contains at least three European species: T. angulata, T. lohsei, and T. szujeckii, with T. szujeckii being a recently described cryptic species from Poland.
Thinusa
Thinusa is a genus of small rove beetles (family Staphylinidae) inhabiting intertidal marine environments. The genus contains at least two described species: Thinusa fletcheri and T. maritima. Based on morphological characters including maxillary structure and abdominal tergite shape, Thinusa is classified in the tribe Athetini rather than Phytosini.
Trichiusa
Trichiusa is a genus of small rove beetles (Staphylinidae: Aleocharinae) comprising approximately 15 described species distributed across North America and Europe. The genus was revised taxonomically in 2015, with several species synonymized under Trichiusa pilosa. Canadian records document presence across multiple provinces and territories from Nova Scotia to Yukon Territory.
Trichiusa hirsuta
Trichiusa hirsuta is a species of rove beetle in the family Staphylinidae, subfamily Aleocharinae, described by Casey in 1906. The genus Trichiusa belongs to the tribe Athetini, a diverse group of small to minute rove beetles. Like other aleocharines, this species likely inhabits leaf litter, soil, or decaying organic matter in forested environments. The specific epithet 'hirsuta' refers to a hairy or bristly appearance, a characteristic feature of this species.
Trichopsenius
Trichopsenius is a genus of termitophilous rove beetles (Staphylinidae: Aleocharinae) first described by Horn in 1877. All known species are obligate symbionts of termites in the genus Reticulitermes (Rhinotermitidae). The genus was recently recorded from China for the first time with the description of Trichopsenius huaxiensis from Guizhou Province. These beetles exhibit specialized behavioral adaptations for integration into termite colonies.
Trichopsenius depressus
Trichopsenius depressus is a species of rove beetle (family Staphylinidae) in the tribe Trichopseniini, first described by John Lawrence LeConte in 1863. The species epithet "depressus" refers to its flattened body form. It belongs to a group of beetles known to be associated with termites, though specific biological details for this species remain poorly documented in published literature. The species is recorded from the southeastern United States.
Xenodusa montana
Xenodusa montana is a rove beetle in the family Staphylinidae, subfamily Aleocharinae. It is a myrmecophilous species, meaning it lives in association with ants. The species is known from western North America.
Xesturida
Xesturida is a genus of rove beetles established by Casey in 1906, placed in the family Staphylinidae. The genus contains at least one described species, X. laevis. Members belong to the tribe Lomechusini within the subfamily Aleocharinae, a group known for diverse ecological associations including myrmecophily.
