A new species of Bythinella: B. walensae is described from Aria spring at Naxos Island, Greece. Cytochrome oxidase subunit I (COI) sequences of mtDNA, as well as internal transcribed spacer (ITS-1) of nuclear ribosomal DNA indicate distinctness of B. walensae. The shell, female reproductive organs and penis are described. The most characteristic of this species are: slender shell, narrow aperture, J-shaped bursa coupled with bulky and spherical receptaculum, and the length ratio of penis arms. Simple anatomy coupled with wide variation ranges overlapping between the species are emphasised.
