Hydrobiusini is a tribe in the subfamily Hydrophilinae of aquatic beetles, and containing 47 species in 9 genera. [1] [2]
Spercheus is a genus of aquatic beetles which are placed in a family of their own, Spercheidae within the Hydrophiloidea. About 20 species are known from around the world except the Nearctic with the majority being from the Oriental and Afrotropical Realms.
Sphaerius is a genus of beetles in the family Sphaeriusidae, comprising 18 species. It is one of the two extant genera in the family, the other being Bezesporum. They are typically found along the edges of streams and rivers, where they feed on algae; they occur on all continents except Antarctica. Three species occur in the United States.
The Hydroscaphidae are a small family of water beetles known commonly as skiff beetles. As of 2010, there are 23 species in the family. Several are recently described.
Hydrophilidae, also known colloquially as water scavenger beetles, is a family of beetles. Aquatic hydrophilids are notable for their long maxillary palps, which are longer than their antennae. Several of the former subfamilies of Hydrophilidae have recently been removed and elevated to family rank; Epimetopidae, Georissidae, Helophoridae, Hydrochidae, and Spercheidae. While the majority of hydrophilids are aquatic, around a third of described species are terrestrial, mostly belonging to the subfamily Sphaeridiinae.
Myxophaga is the second-smallest suborder of the Coleoptera after Archostemata, consisting of roughly 65 species of small to minute beetles in four families. The members of this suborder are aquatic and semiaquatic, and feed on algae.
Hydrophiloidea, known as water scavenger beetles, is a superfamily of beetles. Until recently it included only a single family, the Hydrophilidae, but several of the subfamilies have been removed and raised to family rank. Hydrophiliidae remains by far the largest member of the group, with nearly 3,000 described species. The other families have no more than 400 species. The Histeroidea are closely related and sometimes considered part of a sensu lato Hydrophiloidea. The majority of the clade is aquatic, which is thought to be the ancestral ecology of the group, with some lineages like Sphaeridiinae becoming secondarily terrestrial. Modern representatives of the group first appeared during the Late Jurassic.
Hydrophilus is a genus of beetles in the family Hydrophilidae, the water scavenger beetles. There are 53 species in three subgenera in the genus: Hydrophilus, Dibolocelus, and Temnopterus.
Satonius is a genus of beetles in the family Torridincolidae. It is native to East Asia. The type species, S. kurosawai, was originally described as a species of Delevea. Several other species have been described since.
Hydrophilinae is a subfamily of Hydrophilidae that contains five tribes in 33 genera after the classification was revised by Short and Fikáček in 2013.
Hydrophilini is a tribe in the subfamily Hydrophilinae of aquatic beetles that contains 204 species in 7 genera.
Anacaenini is a tribe in the subfamily Hydrophilinae of aquatic beetles, and it contains 256 species in 6 genera.
Chaetarthriinae is a subfamily in the family Hydrophilidae of aquatic beetles, and it contains 92 species in 8 genera.
Laccobiini is a tribe in the subfamily Hydrophilinae of aquatic beetles, and it contains 367 species in 8 genera.
Sperchopsini is a tribe in the subfamily Hydrophilinae of aquatic beetles, and it contains 24 species in 5 genera.
Hydrobiomorpha is a genus of water scavenger beetles in the family Hydrophilidae. There are 56 extant described species in Hydrobiomorpha, along with several fossil species.
Horelophus walkeri is a small water scavenger beetle that is endemic to New Zealand. It is found in the South Island in the West Coast, Nelson, Buller and Marlborough regions. The preferred habitat of this species are the moss and crevices within the splash zone of waterfalls sourced from fast flowing, clear, cool waterways. The larvae of this species are carnivorous while the adults are herbivores or scavengers. In 2012 the Department of Conservation classified this beetle as Nationally Endangered.
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.
Coelostoma (Holocoelostoma) stultum, is a species of water scavenger beetle widely distributed in Palearctic and Oriental realms from West Pacific towards Indian Ocean, such as China, Taiwan, Andaman Islands, Myanmar, India, Indonesia, Japan, Korea, Malaysia, Mascarene Islands, Nicobar Islands, Oman, Philippines, Saudi Arabia, South Korea, Sri Lanka, Thailand, United Arab Emirates, Oman, and Vietnam.
Coelostoma (Coelostoma) vitalisi, is a species of water scavenger beetle found in China, Taiwan, Japan, India, Indonesia, Japan, Malaysia, Nepal, Singapore, Sri Lanka, Cambodia, Thailand and Vietnam.
Amphiopini is a tribe in the subfamily Hydrophilinae of aquatic beetles, which was first described in 1890 by August Ferdinand Kuwert, and which has been synonymised with Chaetarthriini.
