edit

This genus was originally placed under the subfamily Bellamyinae of Viviparidae. In 2017, it was moved to Viviparinae based on anatomical and genetic data.[2][3]

Species

edit

As of May 2024, WoRMS only recognize one species in this genus, namely Rivularia auriculata (E. von Martens, 1875), the type species of this genus.[2] The original combination is this species was Paludina auriculata Martens, 1875.[2]

A number of species inquirenda have been assigned to this genus, but none have so far been accepted:

  • Rivularia bicarinata[4]
  • Rivularia calcarata[4]
  • Rivularia glandina Heude, 1890
  • Rivularia globosa Heude, 1890
  • Rivularia ovum Heude, 1890
  • Rivularia subelliptica Heude, 1890
