Noteridae
Guides
Hydrocanthus oblongus
Hydrocanthus oblongus is a small burrowing water beetle in the family Noteridae. The species inhabits aquatic environments in the Caribbean and North America. Like other noterids, it has been observed in shallow, muddy substrates where it burrows. The species was described by David Sharp in 1882.
Hydrocanthus regius
Hydrocanthus regius is a species of burrowing water beetle in the family Noteridae, described by Young in 1953. The genus Hydrocanthus comprises small aquatic beetles adapted to burrowing in muddy substrates. Species in this genus are found across North America. Very few observations of H. regius exist in public databases, suggesting it is either genuinely rare, under-recorded, or restricted to specific habitats.
Mesonoterus addendus
Mesonoterus addendus is a small diving beetle species in the family Noteridae, first described by Blatchley in 1920. The species belongs to a genus of burrowing water beetles adapted to aquatic habitats. Based on the limited available records, this species has been documented from the Caribbean and North America. The genus Mesonoterus contains species typically associated with shallow, often temporary aquatic habitats where they burrow in muddy or sandy substrates.
Notomicrus
Notomicrus is a genus of small water beetles in the family Noteridae, first described by Sharp in 1882. Species occur in freshwater habitats across the New World, from North America through Central America to South America and the Caribbean. The genus includes at least 13 described species, with several recent descriptions from Guadeloupe and Suriname. Some species exhibit unusual reproductive traits, including suspected obligate parthenogenesis.
Notomicrus sharpi
Notomicrus sharpi is a small water beetle in the family Noteridae, originally described by Balfour-Browne in 1939. The species is one of four Notomicrus species recorded from Guadeloupe, where it occurs alongside three endemic congeneric species. It is distinguished from these and other New World Notomicrus species primarily by features of the external male genitalia. The species has been documented across the Caribbean, Middle America, and North America.
Suphis
Suphis is a genus of small aquatic beetles in the family Noteridae, first described by Aubé in 1836. The genus contains approximately eleven described species distributed primarily in the Americas, with records from North, Central, and South America. Members of this genus are associated with freshwater habitats, particularly wetlands and slow-moving waters. As part of the Noteridae family, they represent one of several genera within the diverse group of predaceous diving beetles.
Suphisellus gibbulus
Suphisellus gibbulus is a species of burrowing water beetle first described by Aubé in 1838. It belongs to the family Noteridae, a group of small aquatic beetles adapted to burrowing in muddy substrates. The species is known from the United States, though specific details about its biology remain poorly documented.
Suphisellus semipunctatus
Suphisellus semipunctatus is a small burrowing water beetle in the family Noteridae, measuring 2.3–2.6 mm in length. The species was originally described as Suphis semipunctatus by LeConte in 1878 and has also been placed in the genus Pronoterus. It occurs in the eastern United States, ranging west to Texas and Michigan.
