( Figs. 2 A-C)

Holotype (ZMH 79803): shell height 4.5 mm, 3.4 mm width.

Paratypes: 3 specimens (juv.) from type locality ( ZMH 79804 ) ; 3 specimens (1 adult, 2 juv.), 4 specimens. from Göksun suyu, 38 ° 1 ’ 56.26'' N, 36 ° 34 ’ 19.32'' E ( Turkey, Kahramanmaraş Province, Göksun city) (3

specimens destroyed by dissection) in coll. Glöer, 5 specimens (juv.) from type locality ( KSUZM 2014-101 ), 10 specimens (adult) from type locality, 4 specimens (adult) from Göksun suyu in coll. Gürlek.

Locus typicus: Turkey, Kahramanmaraş Province, Göksun city, Törbüzek stream, 38 ° 5'39.41'' N, 36 ° 28 ’ 17.56'' E .

Etymology: Named after the town (Göksun) where the new species was collected.

Description

Shell. The horn-colored solid shell is conical with 4.5 whorls which are slightly convex with a deep suture ( Figs. 2A, C). The whorls are regularly fast growing with a prominent body whorl. The umbilicus is open to slit-like. The aperture is oval with an angle at the top and a thick periostome, flanged at the columella. Juveniles are spherical. The shells are 4.5 mm in height and 3.4 mm broad.

Body. The mantel is black with a whitish border, eye spots are visible. The operculum is yellowish transparent. The penis is triangular without any outgrowth, very broad at the base and acute at the distal end ( Fig. 2B).

Differentiating features: The new species can be easily be distinguished from P. vinarskii Glöer & Georgiev, 2012 by the shell shape (conical in P. goksunensis vs. elongated-conical in P. vinarskii ). Furthermore, additional differences are found in the shell’s size of the compared species (2 mm in P. vinarskii vs. 4.5 mm in P. goksunensis ).

Habitat: The type locality of Pseudamnicola goksunensis n. sp. is a fast flowing stream (with associated canals and pools), with a poorly developed vegetation and a stony bottom. The new species was collected from a small canal. The second locality, Göksunsuyu stream is a big and fast flowing stream ( Fig. 1C). It is worth to note that both localities are not typical habitats for pseudamnicolid snails.
