Gyrophaena keeni
Gyrophaena keeni is a species of rove beetle in the family Staphylinidae, described by Casey in 1911. It belongs to the subfamily Aleocharinae, a diverse group of small, often fungus-associated beetles. The species has a broad distribution across northern North America, with records spanning from Alaska and Yukon to the northeastern United States. Very few observations exist in citizen science databases, suggesting it may be genuinely uncommon or undercollected.
Gyrophaena nanoides
Gyrophaena nanoides is a small rove beetle described by Seevers in 1951. It belongs to the genus Gyrophaena, a group of aleocharine staphylinids characterized by their compact, often flattened bodies and association with fungal substrates. The species is documented from northeastern and north-central North America, with records spanning Canada and the eastern United States. Like other Gyrophaena species, it likely inhabits decaying fungi and organic matter, though specific ecological details remain limited.
