Genus Alvania Risso, 1826 View in CoL
Type species. Alvania europea Risso, 1826 , subsequent designation by Nevill, 1885 (5 Alvania cimex (Linne´, 1758)).
The genus Alvania is here taken in a very broad sense, as a catchall genus for species of Rissoidae having both spiral and axial sculpture on the shell, until some phylogeny is unravelled. This is a difficult task in this speciose group, and requires a broader geographic scope. Most characters currently considered for species definition are highly liable to convergence.
