Caerosternus americanus
Caerosternus americanus is a small clown beetle (family Histeridae) originally described by LeConte in 1844. It is distributed across eastern and central North America, with records from Canada (Ontario, Quebec) and numerous U.S. states. The species belongs to the subfamily Tribalinae within the diverse Histeridae, a family commonly known as clown beetles or hister beetles. Like other members of its family, it is likely associated with decaying organic matter, though specific natural history details remain poorly documented.
Epierus
clown beetles
Epierus is a genus of clown beetles in the family Histeridae, established by Erichson in 1834. The genus contains more than 50 described species. Members of this genus are classified within the subfamily Tribalinae. Like other histerid beetles, they are likely associated with decomposing organic matter, though specific ecological details for the genus remain poorly documented.
Idolia
clown beetles
Idolia is a genus of clown beetles (family Histeridae) comprising six described species, all described by Lewis between 1885 and 1888 except I. laevissima, which was described by LeConte in 1852. The genus belongs to the subfamily Tribalinae and is characterized by features typical of histerid beetles, though specific diagnostic traits for the genus are not well documented in available sources. Species are distributed across North America.
Pseudepierus gentilis
clown beetle
Pseudepierus gentilis is a species of clown beetle in the family Histeridae, first described by Horn in 1883. It belongs to the subfamily Tribalinae and is known from scattered records across the central and southern United States. Like other histerid beetles, it is likely associated with decaying organic matter and wood-boring insect habitats, though specific ecological details remain poorly documented.
Stictostix
Stictostix is a genus of clown beetles (family Histeridae) established by Marseul in 1870. It belongs to the subfamily Tribalinae within the diverse beetle superfamily Histeroidea. The genus contains relatively few documented species and remains poorly studied compared to more speciose histerid genera. Species in this genus are associated with forest floor and decaying wood habitats, where they function as predators of other small invertebrates.
