Chaetarthriinae
Guides
Chaetarthria
Chaetarthria is a genus of water scavenger beetles in the family Hydrophilidae, first described by Stephens in 1835. The genus contains at least 27 described species. These beetles are placed in the subfamily Chaetarthriinae and tribe Chaetarthriini. They are small aquatic beetles associated with freshwater habitats.
Chaetarthria nigrella
Chaetarthria nigrella is a minute water scavenger beetle in the family Hydrophilidae. It is one of the smallest members of its family, typically measuring only 1-2 millimeters in length. The species belongs to the subfamily Chaetarthriinae, a group of tiny beetles often associated with moist or aquatic microhabitats. Very few observations exist for this species, with only three records documented on iNaturalist, suggesting it is either genuinely rare, undercollected, or difficult to detect due to its minute size.
Chaetarthria ochra
Chaetarthria ochra is a species of water scavenger beetle in the family Hydrophilidae. It was described by D.C. Miller in 1974. The species is known from Central America and North America, with records from the southwestern United States (Arizona and California) and Mexico. As a member of the Chaetarthriinae subfamily, it belongs to a group of small hydrophilid beetles often associated with aquatic or semi-aquatic habitats.
Crenitis
Crenitis is a genus of water scavenger beetles in the family Hydrophilidae, containing approximately 19 described species. The genus was established by Bedel in 1881. These beetles belong to the subfamily Chaetarthriinae and tribe Anacaenini. They are aquatic or semi-aquatic insects found in freshwater environments.
Crenitulus suturalis
Crenitulus suturalis is a small water scavenger beetle (family Hydrophilidae) with a broad distribution across the Americas, ranging from the eastern and central United States through Central America to South America. The species was originally described by John Lawrence LeConte in 1866 and has been historically confused with or included in discussions of darkling beetles due to taxonomic name similarities with unrelated species. As a member of the subfamily Chaetarthriinae, it occupies moist or aquatic microhabitats distinct from the arid-adapted darkling beetles with which it shares no close relationship.
