Meridiorhantus orbignyi is an extinct species of predaceous diving beetle in the family Dytiscidae. This species was formerly a member of the genus Rhantus . [1] [2]
Dytiscus latissimus is a species of beetle in family Dytiscidae.
Megadytes ducalis is a species of water beetle in the family Dytiscidae. With a length of 4.75 cm (1.9 in), it is the largest species in the family. Until recently, the species was only known from a single specimen that was collected in the 1800s from an unknown locality in Brazil, although rumors indicate it was found in the bottom of a canoe in the Amazon. In 2019, a study reported 10 additional specimens, all collected from the end of the 19th century, discovered incidentally in various historical collections. While the original holotype lacked any location data, the new specimens all indicate that they were collected in Santo Antonio da Barra in the southern part of Bahia, Brazil. Villagers in the region were involved in insect trade, capturing the much sought after specimens of Hypocephalus armatus found around the region. As a consequence of the lack of recent records, the IUCN lists it as extinct. Considering the absence of information about the species and the limited studies conducted on water beetles in Brazil, it might still survive.
Carabdytes alutaceus is an endangered species of beetle in the family Dytiscidae. It is endemic to New Caledonia, in the southwest Pacific Ocean.
Rhantus is a genus of beetle in family Dytiscidae. There are about 100 species distributed worldwide. They often live in pools and marshy habitat types. Several species have colonized oceanic islands and become endemics.
Acilius is a holarctic genus of diving beetles in the family Dytiscidae and typically has a life cycle that is univoltine.
Carabdytes is a genus of predaceous diving beetles in the family Dytiscidae. Carabdytes upin was formerly the sole species of this genus, but nine species in the genus Rhantus were transferred to Carabdytes as a result of research published by Balke et al. in 2017.
Sandracottus is a genus of beetles in the family Dytiscidae. These aquatic beetles are found in ponds and slow streams from South Asia east to southern Japan, and south to Australia. They are generally about 1–1.5 cm (0.4–0.6 in) long and often have distinctive markings.
Meridiorhantus calidus is a species of predaceous diving beetle in the family Dytiscidae. It is found in North America and the Neotropics. This species was formerly a member of the genus Rhantus.
Carabdytes plantaris is a naturally uncommon species of diving beetle in the family Dytiscidae. It is endemic to New Zealand. For over a century, it was known from just a single specimen collected in 1880 "near Dunedin", and doubts were cast on whether it was actually a New Zealand species at all. In 1986, it was rediscovered when several were collected from a roadside pond near Lake Ellesmere. Carabdytes plantaris is now classed as "naturally uncommon" by the Department of Conservation.
Nartus grapii is a species of beetle in family Dytiscidae, found in the Palearctic. This species was formerly a member of the genus Rhantus.
Nartus sinuatus is a species of predaceous diving beetle in the family Dytiscidae, found in North America. This species was formerly a member of the genus Rhantus.
Colymbetini is a tribe of predaceous diving beetles in the family Dytiscidae. There are about 11 genera and more than 160 described species in Colymbetini.

Rhantus suturellus is a species of predaceous diving beetle in the family Dytiscidae. It is found in North America and the Palearctic.
Rhantus wallisi is a species of predaceous diving beetle in the family Dytiscidae. It is found in North America.
Rhantus gutticollis is a species of predaceous diving beetle in the family Dytiscidae. It is found in North America and the Neotropics.
Rhantus atricolor is a species of predaceous diving beetle in the family Dytiscidae. It is found in North America and the Neotropics.
Meridiorhantus is a genus of predaceous diving beetles in the family Dytiscidae. There are about five described species in Meridiorhantus, found in the Neotropics and North America. These species were formerly members of the genus Rhantus, but were moved to Meridiorhantus when it was created by Balke et al. in 2017.
Caperhantus is a genus of predaceous diving beetles in the family Dytiscidae. There is one described species in Caperhantus, C. cicurius. This species was formerly a member of the genus Rhantus.
Nartus is a genus of predaceous diving beetles in the family Dytiscidae. There are at least two described species in Nartus. These species were formerly members of the genus Rhantus, but were moved to Nartus when it was reinstated by Balke et al. in 2017.
