Descriptions of new and little-known land snail taxa from Turkey, and establishment of a new genus (Gastropoda, Pulmonata: Lauriidae, Enidae and Vitrinidae) Author Ruud, A. Bank Author Henk P. M.

Lowe, 1852 : 276 . Type species (by subsequent designation of Pilsbry, 1922: 67): Pupa [ Leiostyla ] vincta R.T. Lowe, 1852 . The genus Leiostyla has a disjunct distribution pattern (Manganelli, Giusti & Delle Cave, 1990 ) and has been split into two genera by Schileyko (1998a) , namely Leiostyla and Euxinolauria Lindholm, 1924 . In addition, Schileyko divided both genera into several subgenera. However, the split between Leiostyla and Euxinolauria is already problematic, as has been discussed by Gittenberger & Pieper (1988) , Hausdorf (1990) , Pokryszko & Waldén (1992) and Walther & Hausdorf (2015) . Therefore, we do not follow the system that was proposed by Schileyko, and continue to use Leiostyla in its classical sense. A considerable number of Leiostyla species live in Turkey, especially in the northeastern part of the country (Caucasian region). Some species have been described west of this region: L. schweigeri Götting, 1963 ; L. superba Hausdorf, 1990 ; the polytypic L. paphlagonica Hausdorf, 1990 ; L. crassilabris Hausdorf, 1990 ; and L. zilchi Subai, 1993 . Because of the marked differences between L . superba and L. zilchi and the large geographical disjunction, we consider the latter a separate species, and not a subspecies of L. superba as was originally proposed by Subai (1993) . Here we describe another subspecies of L. paphlagonica , and describe a new species that is morphologically related to L. superba and L. zilchi .
