Colydiinae
Guides
Aulonium
Aulonium is a genus of cylindrical bark beetles in the family Zopheridae, subfamily Colydiinae. Members are predators of other bark beetles and have been studied for their potential role in biological control. The genus contains approximately 17 described species distributed across multiple continents. At least one species, Aulonium ruficorne, has been documented as a specialized predator within bark beetle galleries.
Coxelus
cylindrical bark beetles
Coxelus is a genus of cylindrical bark beetles in the family Zopheridae, established by Dejean in 1821. The genus comprises approximately 10 described species distributed across multiple continents. Members are classified within the subfamily Colydiinae and tribe Synchitini. The genus has been documented in Denmark and other regions, with 45 observations recorded on iNaturalist.
Eucicones marginalis
Eucicones marginalis is a species of cylindrical bark beetle in the family Zopheridae, described by Melsheimer in 1846. The genus Eucicones belongs to the subfamily Colydiinae, a group commonly known as cylindrical bark beetles due to their elongated, parallel-sided body form. Members of this family are primarily associated with dead and decaying wood, where they feed on fungi or are predatory on other wood-inhabiting insects. The species is documented from North America, with records from Ontario, Canada.
Monoedus
Monoedus is a genus of cylindrical bark beetles in the family Zopheridae. It contains approximately eight described species distributed primarily in the Neotropical region. The genus was established by G.H. Horn in 1882 and is currently classified within the tribe Adimerini, subfamily Colydiinae. Species in this genus are characterized by their elongated, cylindrical body form typical of many colydiine beetles.
Namunaria pacifica
Namunaria pacifica is a species of cylindrical bark beetle in the family Zopheridae, first described by Horn in 1878. It is one of approximately 20 species in the genus Namunaria, which belongs to the tribe Synchitini. The species is found in western North America, with records from British Columbia, Canada. Like other members of its genus, it is associated with dead wood habitats.
Pseudocorticus blairi
Pseudocorticus blairi is a species of cylindrical bark beetle in the family Zopheridae, subfamily Colydiinae. Described by Hinton in 1935, this species belongs to a genus of small, elongate beetles associated with dead wood habitats. The genus Pseudocorticus occurs in Middle America, with this species recorded from the region. As with many colydiine beetles, detailed biological information remains limited.
Rhagodera
cylindrical bark beetles
Rhagodera is a genus of cylindrical bark beetles in the family Zopheridae, established by Mannerheim in 1843. The genus comprises at least four described species distributed in North America. Members of this genus are classified within the tribe Rhagoderini and subfamily Colydiinae. These beetles are associated with bark habitats, though specific ecological details remain poorly documented.
Synchitini
cylindrical bark beetles
Synchitini is a tribe of cylindrical bark beetles in the family Zopheridae, established by Redtenbacher in 1845. The tribe contains approximately 19 genera and at least 40 described species. Members of this group are characterized by their elongated, cylindrical body form adapted for living under bark. A fossil genus, †Paleoendeitoma, has been described from Burmese amber dating to the Cenomanian period.
