Liadytiscus is an extinct genus of predaceous diving beetles in the family Dytiscidae. There are at least three described species in Liadytiscus. [1] [2] [3] [4] [5]
These three species belong to the genus Liadytiscus:
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.
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.
Catiniidae is an extinct family of beetles in the order Coleoptera.
Coptotomus is a genus of predaceous diving beetles in the family Dytiscidae, the only genus of the subfamily Coptotominae. There are about six described species in Coptotomus, found in North America and the Neotropics.
Hydrodytes is a genus of predaceous diving beetles in the family Dytiscidae. There are at least three described species in Hydrodytes. It is found in North America and the Neotropics.
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.
Nartus sinuatus Black with dark rufous legs; posterior margin of pronotum arched just before hind angles(3) 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.
Hydroporus pervicinus is a species of predaceous diving beetle in the family Dytiscidae. It is found in North America.
Liadytidae is an extinct family of adephagan beetles. There are at least two genera and about seven described species in Liadytidae. They are known from the Early Jurassic to Early Cretaceous of Asia. They are members of the clade Dytiscoidea, and like other members of that group were adapted for aquatic life.
Liadytiscinae is a subfamily of extinct predaceous diving beetles in the family Dytiscidae. There are about 5 genera and 10 described species in Liadytiscinae. All currently known members of the subfamily are known from the Early Cretaceous Jehol Biota of China.
Ereboporus is a genus of predaceous diving beetles in the family Dytiscidae. There is one described species in Ereboporus, E. naturaconservatus, found in North America.
Neobidessodes is a genus of predaceous diving beetles in the family Dytiscidae. There are about 10 described species in Neobidessodes. They are found in Australasia. The genus was first described in 2009, and the type species is N. denticulatus.
Sinoporus is an extinct genus of predaceous diving beetles in the family Dytiscidae. There is one described species in Sinoporus, S. lineatus.
Liadroporus is an extinct genus of predaceous diving beetles in the family Dytiscidae. There is one described species in Liadroporus, L. elegans.
Mesoderus is an extinct genus of predaceous diving beetles in the family Dytiscidae. There are at least four described species in Mesoderus.
Liadyxianus is an extinct genus of predaceous diving beetles in the family Dytiscidae. There is one described species in Liadyxianus, L. kirejtshuki.
Mesodytes is an extinct genus of predaceous diving beetles in the family Dytiscidae. There is one described species in Mesodytes, M. rhantoides.
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.
