Bythinella kambosensis n. sp. [ fig. 2.4 ]

Type locality: Greece, Messenia , western slope of the Taygetos Mountains, spring along the road between Akrogiali and Kambos, about 2.5 km from the turnoff from the coastal road, N 36°56'56.0" / E 22°10'00.8", 222 m a.s.l., 18.04.2018, leg. Hans-Jürgen & Andrea Hirschfelder.

Type Material: Holotype ( ZMH 140682 ): Shell height 2.95 mm, shell width 1.8 mm . Paratypes from type locality: ZMH (140683/2), coll. Hirschfelder (7 adult, 7 subadult) .

Etymology: The new species is named after Kambos Gorge, into which the source drains.

Description:

Shell: The shell is slightly concial ovate with a small apex. The surface is silky. The 4.5-5 whorls are slightly convex with a clear suture. The body whorl takes about 0.75 of shell height. The aperture is ovate, slightly angled at the top, with a sharp peristome. The umbilicus is closed. The shell is 2.7-3.0 mm high and 1.7-1.8 mm broad.

Differentiating characters: The new species differs from the neighbouring B. taygetensis n. sp. by the stout and more conical shell (length to width ratio of 1.7, which is about 1.8 in B. taygetensis n. sp.) and from most of the Greek species by a charcteristically silky sheen.

Associated species: Pseudamnicola exilis (Frauenfeld, 1863) .

Distribution: Only known from type locality on the western slope of the Taygetos Mountains.
