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.[1]
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
