Taxonomy
Over fifty species worldwide have been placed in (sub)genus ''Megastomia''
Monterosato, 1884 by a number of authors (e.g. Saurin, 1959, 1962; Peñas & Rolán, 1999; Giannuzzi-Savelli et al. (2014). On the basis of 16s mtDNA sequence data, Schander et al. (2003) distinguished, and placed in ''Megastomia'', two species (''M. conoidea''
(Brocchi, 1814) and ''M. corimbensis''
(Schander, 1994)), which clustered separately from other species placed in ''
Odostomia
''Odostomia'' is the most speciose genus of minute sea snails, pyramidellid gastropod mollusks. This genus is placed in the family Pyramidellidae in the subfamily Odostomiinae. There are several hundred species in this diverse genus (Schander et ...
''
Fleming, 1813. However Høisæter (2014: 34) correctly pointed out that the type species ''Odostomia conspicua''
Alder, 1850 "is a typical ''Odostomia s.s.'' and has few traits in common with ''O. conoidea''".
Considering the large number of species involved, and considering that for most of these species ''Odostomia'' is probably not more appropriate, the published combinations with ''Megastomia'' are nevertheless retained by the database
WoRMS as "accepted" until more data become available.
