Simnia

Simnia is a genus of sea snails, marine gastropod molluscs in the family Ovulidae.

==Taxonomy== Dolin & Ledon (2002) considered that the lectotype of Simnia nicaeensis Risso, 1826, type species of Simnia, is a juvenile specimen of Simnia spelta (Linnaeus, 1758) type species of Neosimnia Fischer, 1884. This makes Simnia an objective synonym of Neosimnia. Accordingly, all the species treated in Lorenz & Fehse (2009) under Neosimnia should thereby be accepted under Simnia. Likewise, all the species treated by Lorenz & Fehse (2009) under Simnia should thereby be accepted under Xandarovula Cate, 1973. The assumptions of Dolin (Dolin & Ledon, 2002) are based on interpretations but not on the examination of the type material. Fehse (2016) has confirmed the vaility of the genus Neosimnia because the lectotype of Simnia nicaeensis Risso, 1826, type species of Simnia, is never a juvenile specimen of Simnia spelta (Linnaeus, 1758) type species of Neosimnia Fischer, 1884.
