Ochthebius is a genus of minute moss beetles in the family Hydraenidae. There are at least 460 described species in Ochthebius. [1] [2] [3]
Hydraenidae is a family of very small aquatic beetles, sometimes called "Minute moss beetles", with a worldwide distribution. They are around 0.8 to 3.3 mm in length. The adults store air on the underside of the body as well as beneath the elytra which allows them to crawl underwater, often on the underside of the water surface tension, though they cannot swim. Some species have gills that effectively allow them to stay underwater indefinitely. Larvae vary from being fully terrestrial, to being aquatic at least in their earliest instars. The diet of hydraenid larvae and adults is thought to consist of algae, spores and other plant matter. At least some hydraenid adults use stridulation to communicate. There are around 1,300 species in 42 genera.
Hygrobia is a genus of aquatic beetles native to Europe, North Africa, China and Australia. It is the only genus in the family Hygrobiidae, also known as the Paelobiidae. These are known commonly as squeak beetles or screech-beetles.
Ancyronyx, commonly known as spider water beetles or spider riffle beetles, is a genus of aquatic riffle beetles from North America, South Asia, China, and Southeast Asia. They are small beetles with extremely long legs ending in strong claws. Both the adults and the larvae are found underwater in the shallow riffles of streams and rivers, clinging to rocks or submerged wood. They feed on algae and decaying wood tissue. The genus contains twenty-one species, eleven of which are endemic to the Philippines.
Neochthebius vandykei is a species of minute moss beetle in the family Hydraenidae. It is found in North America.
Neochthebius is a genus of minute moss beetles in the family Hydraenidae. There are at least two described species in Neochthebius.
Ochthebiinae is a subfamily of minute moss beetles in the family Hydraenidae. There are about 14 genera and more than 650 described species in Ochthebiinae.
Hydraena is a genus of minute moss beetles in the family Hydraenidae. There are more than 990 described species in Hydraena.
Ochthebius puncticollis is a species of minute moss beetle in the family Hydraenidae. It is found in Central America and North America.
Gymnochthebius fossatus is a species of minute moss beetle in the family Hydraenidae. It is found in the Caribbean Sea, Central America, North America, and South America.
Gymnochthebius is a genus of minute moss beetles in the family Hydraenidae. There are more than 60 described species in Gymnochthebius.
Ochthebius lineatus is a species of minute moss beetle in the family Hydraenidae. It is found in Central America, North America, and South America.
Limnebius alutaceus is a species of minute moss beetle in the family Hydraenidae. It is found in North America.

Hydraena circulata is a species of minute moss beetle in the family Hydraenidae. It is found in Central America and North America.
Ochthebius marinus, the marine moss beetle, is a species of minute moss beetle in the family Hydraenidae. It is found in Europe and Northern Asia, North America, and Southern Asia.
Epimetopidae is a family of semi-aquatic beetles belonging to the Hydrophiloidea. They are found in sand and gravel at the edges of streams, rivers and shallow freshwater ponds. These beetles are shorter than half a centimeter long and have a pronotum with a central projection forming a shelf above the head. On the underside of the abdomen only four sternites are visible. There are approximately 72 described species in three genera, Epimetopus which is restricted to the New World, mostly Neotropical, Eupotemus with two Afrotropical species and Eumetopus with some Oriental species. Females carry their eggcases on the underside of the abdomen. The larvae are probably carnivorous based on their mouthparts and likely live in the same habitats as the adults.
Aspidytidae is a family of aquatic beetles of the suborder Adephaga, described in 2002 from specimens in South Africa and China. There are only two known species in the family and these were originally described in the genus Aspidytes, but later the new genus Sinaspidytes was erected for the species found in China. The family can also be referred to by its trivial name cliff water beetles.
Ignacio “Nacho” Ribera Galán was a Spanish entomologist who authored 104 species, 16 genera, 3 subgenera, and 1 family of beetles, along with two species of worms (Nematomorpha).
Gymnochthebius seminole is a species of tiny beetle in the family Hydraenidae. It is known only from a single adult male specimen collected in a "sawgrass-mangrove area" along the Snake Bight Trail north of Flamingo in Everglades National Park, Florida on 27 August 1965.
Hydrovatus rufoniger, is a species of predaceous diving beetle found in India, Bangladesh, Myanmar, Sri Lanka, China, Sumatra, Malaysia, Singapore, Thailand, Vietnam and Australian region.
