Regimbartia is a small genus of beetles belonging to the family Hydrophilidae comprising ten species distributed throughout Africa, South Asia, South East Asia and Australia. [1] [2] [3]
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.
The Dytiscidae – based on the Greek dytikos (δυτικός), "able to dive" – are the predaceous diving beetles, a family of water beetles. They occur in virtually any freshwater habitat around the world, but a few species live among leaf litter. The adults of most are between 1 and 2.5 cm (0.4–1.0 in) long, though much variation is seen between species. The European Dytiscus latissimus and Brazilian Megadytes ducalis are the largest, reaching up to 4.5 cm (1.8 in) and 4.75 cm (1.9 in) respectively. In contrast, the smallest is likely the Australian Limbodessus atypicali of subterranean waters, which only is about 0.9 mm (0.035 in) long. Most are dark brown, blackish, or dark olive in color with golden highlights in some subfamilies. The larvae are commonly known as water tigers due to their voracious appetite. They have short, but sharp mandibles and immediately upon biting, they deliver digestive enzymes into prey to suck their liquefied remains. The family includes more than 4,000 described species in numerous genera.
Copelatus is a large genus of small diving beetles. There are some 470 described species in the genus, found worldwide, but they are most diverse in tropical South America, Africa and South-East Asia. Copelatus are often black or brown in color, many species of Copelatus possessing visible longitudinal furrows down the dorsal side of the wings of both sexes.
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.

Orectogyrus is a genus of beetles in the family Gyrinidae, containing the following species:
Hydrochara is a genus of hydrophilid beetles with 23 species in North America, Europe, Asia, and Africa.
Sphaeridium is a genus of beetles in the family Hydrophilidae, the water scavenger beetles. They occur in Europe, and some species have been introduced to North America.
Laccobius is a genus of water scavenger beetles in the family Hydrophilidae. There are more than 80 described species in Laccobius.
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.
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.
Pelthydrus is a genus of beetles belonging to the family Hydrophilidae. The genus has primarily Oriental origin and consists with 65 described species.
Regimbartia attenuata, commonly known as Japanese water scavenger beetle, is a species of water scavenger beetle widely distributed in the Old World, from northern Australia and Japan westward to the countries of Arabian Peninsula, including Oman and Yemen. It is the only species of the genus occurring in the Arabian Peninsula.
Hyphoporus nilghiricus, is a species of predaceous diving beetle found in India, Pakistan, and Sri Lanka. Sometimes, the species is included into the genus Hygrotus by some authors.
Hydrovatus lyratus, is a species of predaceous diving beetle widespread in South Asia, South East Asia and Australian region.
Laccophilus anticatus, is a species of predaceous diving beetle found in South and South East Asia.
Amphiops is a genus of aquatic beetles in the tribe Amphiopini of the family Hydrophilidae, first described by Wilhelm Ferdinand Erichson in 1843.
Allocotocerus is a genus of water beetles in the family Hydrophilidae, first described by Ernst Gustav Kraatz in 1883. The decision for synonymy is based on Hansen (1999).
