Species
There are two species:
- Marisa cornuarietis (Linnaeus, 1758)[2]
- Marisa planogyra Pilsbry, 1933[2]
Phylogeny
Based on analysis of mitochondrial 12S ribosomal RNA, 16S ribosomal RNA, and the cytochrome-c oxidase I (COI) gene, M. cornuarietis is a sister clade to M. planogyra and Asolene spixii, indicating that genus Marisa is not monophyletic.[2]
