Paroster is a genus of beetles in the family Dytiscidae, containing the following species: [2]
together with these (listed as valid by the Australian Faunal Directory): [1]
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.
Hygrobia is a genus of aquatic beetles native to Europe, North Africa, China and Australia. It is the only genus in the family Hygrobiidae, also known as the Paelobiidae. These are known commonly as squeak beetles or screech-beetles.

Limbodessus leysi is a carnivorous subterranean water beetle, in the Bidessini tribe of the Dytiscidae family. It was first described in 2006, and the species epithet honours the entomologist, Remko Leys.
Neobidessodes flavosignatus is a carnivorous subterranean water beetle, in the Bidessini tribe of the Dytiscidae family. It was first described in 1922 by Albrecht Zimmermann as Bidessus flavosignatus. It was assigned to the genus Bidessodes by Watts in 1978, and to the new genus of Neobidessodes in 2009 by Hendrich and others.

Neobidessodes grossus is a carnivorous subterranean water beetle, in the Bidessini tribe of the Dytiscidae family. It was first described in 1922 by Albrecht Zimmermann as Bidessus grossus. It was assigned to the genus Bidessodes by Watts in 1978, and to the new genus of Neobidessodes in 2009 by Hendrich and others.
Neobidessodes bilita is a carnivorous subterranean water beetle, in the Bidessini tribe of the Dytiscidae family. It was first described in 1978 by Chris H.S. Watts as Bidessodes bilita, and reassigned to the genus of Neobidessodes in 2009 by Hendrich and others.
Paroster caecus is blind beetle in the Hydroporini tribe of the subfamily Hydroporinae in the Dytiscidae family. It was first described by Chris Watts in 1982 as Terradessus caecus. It was transferred to the genus, Paroster, in 2016 by Toussaint, Hendrich and others.
