Clausilioides Lindholm, 1925

Clausilioides Lindholm, 1925: 29 , 38. Type species (by monotypy): Buliminus (Brephulus) biplicatus Retowski, 1889 .

So far, only two species have been assigned to the genus Clausilioides , namely C. biplicatus (Retowski, 1889) (synonym: eplicatus Lindholm, 1913) and C. filifer ( Lindholm, 1913) . We here describe another two species. The genus seems to be endemic for the northeastern part of Turkey, although both biplicatus and filifer have originally been described from Georgia (but only found in deposition of the Çoruh river).

A characteristic feature of the genus is the presence of a well developed palatal fold in the last whorl. This is a rare character within the family Enidae . It has been reported in Pseudonapaeus entoptyx ( Lindholm, 1925) (the type species of Siraphorus Lindholm, 1925), Siraphoroides moltschanovi (Likharev & Rammelmeier, 1952) (a monotypic genus), and various species of the genus Pupopsis Gredler, 1898 . The first two species are known from Kirgizstan, whereas Puposis is distributed in the northwestern part of China (Xinjiang at the border of Kirgistan and Kazachstan) as well as in central China (SE Gansu and N Sichuan). For a review on Pupopsis see Wu & Gao (2010). Furthermore, a palatal fold is seen in Buliminus glabratus (Mousson, 1861) from the central part of Israel.
