Cyprididae is "the most diverse group of freshwater ostracods".[2] It contains over 1000 species, which represents 50% of the known species of freshwaterostracods (other speciose families include Candonidae, with 25%, and Limnocytheridae, with 10%).[3] Around 60% of genera in the family are endemic to a single zoogeographic region.[3] The family contains 16 subfamilies, and is most diverse in the Afrotropical realm, with over 300 species in 45 genera.[3] Many Cyprididae occur in temporary water bodies and have drought-resistant eggs, mixed/parthenogenetic reproduction and ability to swim. These biological attributes pre-adapt them to form successful radiations in these habitats.[4]Bennelongia is an interesting of the family Cyprididae. It may be the last true descendant of the Mesozoic (and now extinct) lineage of Cypridea, which was a dominant lineage of ostracod in non-marine waters in the Cretaceous.[3]
