Bythinella taygetensis n. sp. [ fig. 2.3 ]

Type locality: Greece, Laconia , eastern slope of Taygetos Mountains, Anavriti, spring at the southern edge of the village, N 37°01'48.1" / E 22°22'10.8", 890 m a.s.l., 15.04.2018, leg. Hans-Jürgen Hirschfelder.

Type Material: Holotype ( ZMH 140680 ): Shell height 2.8 mm, shell width 1.6 mm . Paratypes from type locality: ZMH (140681/1), coll. Hirschfelder (5 adult, 1 subadult) .

Etymology: The new species is named after the Taygetos Mountains.

Description:

Shell: The shell is elongated cylindrical. The 4.5-5 whorls are slightly convex with a clear suture. The body whorl takes about 0.7 of shell height. The aperture is ovate, angled at the top, with a sharp peristome which has a brown border. The umbilicus is closed. The shell is 2.4-2.9 mm high and 1.4-1.6 mm broad.
