The genus Multidentula is known from the Caucasus, Armenia, Georgia, Azerbaijan, northwestern Iran and the northern half of Turkey; its presence in Cyprus is questionable ( Bank & Neubert, 2015: 73). The following species belong to the genus: lamellifera (Ross- mässler, 1858), nachicevanjensis ( Hudec, 1972) , ovularis (Olivier, 1802) , pupoides (Krynicki, 1833) , ridens (Nägele, 1906) and squalina (L. Pfeiffer, 1848) . The latter species is polytypic and is almost endemic for Turkey. Forcart (1940: 197-199, pl. 3 figs 64-65) mentioned M. s. squalina and M. s. eudoxina (Nägele,1894) for Turkey. Based on a single shell, Lindholm (1922b: 358-359) described Chondrula acutior from Georgia; this shell (holotype) has been figured by Sysoev & Schileyko (2009: fig. 38E) under the name Euchondrus acutior . It has never been found again after the de- scription from Lindholm. Our revision revealed that this taxon is also distributed in the northeastern part of Turkey, and that it is a subspecies of M. squalina . We here characterize this virtually unknown subspecies, and also describe a new species from Turkey.
