Piestinae
Guides
Hypotelus
Hypotelus is a genus of rove beetles in the family Staphylinidae, subfamily Piestinae. The genus was established by Erichson in 1839 and contains species characterized by their association with decaying organic matter. Members of this genus are part of the diverse staphylinid fauna that contribute to decomposition processes in forest ecosystems.
Piestus
flat rove beetles
Piestus is a genus of flat rove beetles established by Gravenhorst in 1806. The genus contains more than 30 described species and is classified within the subfamily Piestinae of the family Staphylinidae. Members of this genus are characterized by their dorsoventrally flattened body form, an adaptation associated with their habitat preferences. The genus is part of the diverse rove beetle fauna, though specific ecological details for most species remain poorly documented.
Piestus extimus
Piestus extimus is a species of flat rove beetle in the family Staphylinidae, described by Sharp in 1887. It belongs to the subfamily Piestinae, a group characterized by their dorsoventrally flattened body form. The species has been documented in limited observations, with records from the southwestern United States and Mexico. As with other members of Piestus, it likely inhabits moist microhabitats in forested or riparian environments.
Siagonium americanum
Siagonium americanum is a species of flat rove beetle in the family Staphylinidae. It occurs in North America with records from Canada (Ontario) and multiple U.S. states across the eastern and central regions. The species was first described by F.E. Melsheimer in 1844 under the basionym Prognatha americana. As a member of the subfamily Piestinae, it shares the characteristic flattened body form typical of this group.
Siagonium stacesmithi
Siagonium stacesmithi is a rove beetle in the subfamily Piestinae, described by Hatch in 1957. The species is known from scattered records across northern North America, including western Canada, the Yukon, and parts of the western and northeastern United States. Like other members of Siagonium, it is a small, elongate beetle associated with forest floor habitats. It remains poorly known biologically, with only a handful of documented observations.
