Albinaria evelynae spec. nov. is described from the Peloponnese and classified next to A. grayana as its sister species on the basis of autapomorphies in shell shape and sculpture. Doing so, one more example is given of two conchologically very similar species, with a G-type and an Ntype clausilial apparatus, respectively. Obviously, the clausilial apparatus cannot be used to distinguish the genera Isabellaria and Albinaria. In the former genus only the G-type occurs, whereas in the latter, both G- (rarely) and N-types are found. This has nomenclatorial consequences, which are summarized.
