Enochrus, a genus of water scavenger beetles, is the third-largest genus of hydrophilids with 229 species in six subgenera worldwide. [1] [2] [3] [4]
These 67 species belong to the genus Enochrus:

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.
Zopheridae is a family of beetles belonging to Tenebrionoidea. It has grown considerably in recent years as the members of two other families have been included within its circumscription; these former families are the Monommatidae and the Colydiidae, which are now both included in the Zopheridae as subfamilies or even as tribe of subfamily Zopherinae. Some authors accept up to six subfamilies here, while others merge all except the Colydiinae into the Zopherinae.
Agabus is a large genus of predatory aquatic beetles in the family Dytiscidae, proposed in 1817 by William Elford Leach and named after Agabus, an early follower of Christianity. The adult beetles are moderate-sized, 5 to 14 mm long. The genus is primarily Holarctic in distribution, with only a few species known from the Afrotropical and Neotropical realms. Three species of Agabus, namely A. clypealis, A. discicollis and A. hozgargantae are endangered according to the IUCN Red List. The division into subgenera is not widely accepted. However, a number of species groups are recognized after the works of David J. Larson and Anders N. Nilsson. The genus is probably polyphyletic or paraphyletic. In a recent study of mitochondrial DNA, Agabus was found paraphyletic with respect to several of the species groups of Platambus, a closely related genus in the tribe Agabini. Lately the taxonomy of the genus has been revised, and some groups of species were transferred from Agabussensu stricto to other genera in the tribe Agabini.
Gyrinus is a genus of small aquatic whirligig beetles in the family Gyrinidae native to the Palearctic, the Near East, the Nearctic, North Africa, Asia and Australia.
Hydrochus is the only living genus of beetle in the family Hydrochidae, which belongs to the superfamily Hydrophiloidea, and was formerly treated as a subfamily of Hydrophilidae. Hydrochus includes about 180 species, which are found worldwide. The name "Hydrochus" has also been used for a fly genus in the family Dolichopodidae, but this is a junior subjective synonym of the genus Rhaphium.
Haliplus is a genus of crawling water beetles in the family Haliplidae. There are at least 180 described species in Haliplus. They are found worldwide, except for Antarctica, living among algae and aquatic vegetation at edges of ponds, lakes, and streams. They range in size from 1.75 to 5 mm.
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.
Berosus is a genus of beetles in the family Hydrophilidae, the water scavenger beetles. The genus contains 273 species. It is distributed worldwide.
Tropisternus is a genus of hydrophilid beetles with 63 species in five subgenera in North and South America.
Helochares is a genus of water scavenger beetles in the family Hydrophilidae, represented by 161 described species. It is distributed across the Afrotropical, Australasian, Indo-Malayan, Nearctic, and Palearctic realms.
Acidocerinae is a subfamily in the family Hydrophilidae of aquatic beetles, and it contains over 500 species in 23 genera.
Anacaena is a genus of water scavenger beetles in the subfamily Hydrophilinae. It is an extant genus but there is at least one fossil species.
Cercyon is a genus of water scavenger beetles in the family Hydrophilidae. There are at least 50 described species in Cercyon.
Mycetophagus is a genus of hairy fungus beetles in the family Mycetophagidae. There are at least 20 described species in Mycetophagus.
Dactylosternum is a genus of water scavenger beetles in the family Hydrophilidae. There are more than 20 described species in Dactylosternum.
Cryptopleurum is a genus of water scavenger beetles in the family Hydrophilidae. There are about 11 described species in Cryptopleurum.
Coelostoma is a genus of beetles belonging to the family Hydrophilidae. The genus was first described by Brullé in 1835. The genus has cosmopolitan distribution, with 111 described species, representing one of the most diverse genera of Hydrophilidae.
Agraphydrus is a genus of water scavenger beetle in the family Hydrophilidae represented by 205 described species. It is distributed across the Afrotropical, Australasian, and Indomalayan realms.
Crephelochares is a genus of water scavenger beetle in the family Hydrophilidae represented by 29 described species. It is distributed across the Afrotropical, Australasian, Indo-Malayan, and Palaearctic realms.
Peltochares is a genus of water scavenger beetles in the family Hydrophilidae represented by eight described species. It is distributed across the Afrotropical, Australasian, Indo-Malayan, and Palaearctic realms.
