Taxonomy

This and other Western American species were attributed to Alvinia Monterosato, 1884, following Keen (1971); nevertheless it is not proved to be more related to the Mediterranean type species Alvania weinkauffi Weinkauff, 1868 than to other Alvania s.l. and is therefore retained in Alvania.

Description

The length of the shell varies between 1 mm and 2 mm.

Distribution

This species occurs off the Monserate Island, Gulf of California; also off the Galapagos Islands
