Ceradryops is a genus of long-toe water beetles in the family Dryopidae. There are three described species in this genus. [1] [2] [3]
A water beetle is a generalized name for any beetle that is adapted to living in water at any point in its life cycle. Most water beetles can only live in fresh water, with a few marine species that live in the intertidal zone or littoral zone. There are approximately 2000 species of true water beetles native to lands throughout the world.
Howard Everest Hinton was a British entomologist and Professor who studied beetles.
Byrrhoidea is a superfamily of beetles belonging to Elateriformia that includes several families which are either aquatic or associated with a semi-aquatic habitat. Other than the superfamily Hydrophiloidea, most of the remaining Polyphagan beetles which are aquatic are in this superfamily.
Syntelia is a genus of beetles. It is the only genus in the family Synteliidae. There are seven known species, which are native to high-elevation regions in southern North America from central Mexico to Guatemala, and in eastern Asia, from India to Japan and eastern Russia. They are generally associated with rotting logs, typically found under bark, though the Mexican species S. westwoodi has been found inside large decaying columnar cacti. Adults and larvae are predatory, feeding on insect larvae. A fossil species, Syntelia sunwukong, is known from the Late Cretaceous (Cenomanian) aged Burmese amber of Myanmar. Adults are around 1–3.5 centimetres (0.39–1.38 in) in length. The characteristics of the family and genus include geniculate antennae with 3-segmented club, elongate body, narrowly separated coxae and tarsi with bisetose empodia. Only one abdominal segment is exposed behind elytra. The genus described by John O. Westwood in 1864, while the family was erected by George Lewis in 1882. They are members of Histeroidea, which also includes clown beetles (Histeridae).
Pericoptus punctatus is a sand scarab beetle that is endemic to New Zealand. It is a smaller and similar New Zealand scarab beetle species to Pericoptus truncatus.
Beetles of the genus Helichus are found worldwide apart from in Australia and Antarctica. Adults reach 1–8 millimetres (0.04–0.31 in) long and live in aquatic or riparian environments. The larvae are land-dwelling which may be unique in water living insects.
Dryopidae is a family of beetles, commonly named long-toed water beetles, in the superfamily Byrrhoidea. It was described by Gustaf Johan Billberg in 1820.
Elminae is a subfamily of riffle beetles in the family Elmidae. There are at least 120 genera and more than 1,300 described species in Elminae.
Hexacylloepus is a genus of riffle beetles in the family Elmidae. There are about 19 described species in Hexacylloepus.
Grouvellinus is a genus of beetle in the family Elmidae. As of 2018, over forty species are recognized, including:
Macronychus is a genus of riffle beetles in the family Elmidae. There are about 11 described species in Macronychus.
Postelichus is a genus of long-toed water beetles in the family Dryopidae. There are at least four described species in Postelichus.
Hensel's snake is a species of snake in the subfamily Dipsadinae of the family Colubridae. The species is endemic to southern Brazil, and it is monotypic in the genus Ditaxodon.
Larainae is a subfamily of riffle beetles in the family Elmidae. There are more than 20 genera and 160 described species in Larainae.
Macronychini is a tribe of riffle beetles in the family Elmidae. There are more than 20 genera and 80 described species in Macronychini.
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.
Ilamelmis foveicollis, is a species of riffle beetle found in Sri Lanka.
Ceradryops punctatus, is a species of long-toed water beetle found in Sri Lanka.
