Rivularia is a genus of freshwater snails with a gill and an operculum, aquatic gastropod mollusks in the family Viviparidae. [1] Species in this genus is distributed only along the Xiang River region of Hunan province, People's Republic of China.
This genus was originally placed under the subfamily Bellamyinae of Viviparidae. In 2017, a reference moved the genus to Viviparinae according to anatomical and genetic data. [1] [2]
As of 3 September 2021 [update] , WoRMS only recognize one species in this genus, namely Rivularia auriculata (E. von Martens, 1875), the type species of this genus. [1] The original combinatiion is this species was Paludina auriculata Martens, 1875. [1]
Helix is a genus of large, air-breathing land snails native to Europe and the Mediterranean region. They are the type genus of the family Helicidae, and are among the first animal genera described by Carl Linnaeus. Members of the genus first appeared during the Oligocene. Like most land snails, Helix species are hermaphroditic, and like other helicids, a courting pair will impale each other with hormone-rich love darts prior to exchanging sperm. Well-known species include Helix pomatia and Helix lucorum. Cornu aspersum – another well-known helicid – was originally described as a member of Helix, but the prevailing classification places it as the sole member of the sister genus Cornu.
