Bythinella ellinikae n. sp. [ fig. 2.6 ]

Type locality: Greece, Laconia , Neapoli Peninsula , spring along the road from Xifias to Elliniko, 400 m east of Elliniko , N 36°36'35.0" / E 22°59'15.3", 500 m a.s.l., 17.04.2018, leg. Hans-Jürgen & Andrea Hirschfelder.

Type Material: Holotype ( ZMH 140686 ): Shell height 2.9 mm, shell width 1.7 mm . Paratypes from type locality: ZMH (140687/2), coll. Hirschfelder (8 adult) .

Etymology: The new species is named after the village Elliniko.

Description:

Shell: The shell is cylindrical with a small apex. The 4.5-5 whorls are convex with a deep suture. The body whorl takes about 0.6 of shell height. The aperture is ovate, slightly angled at the top with a sharp peristome which has a dark yellowish border. The umbilicus is closed. The shell is 2.7-2.9 mm high and 1.6- 1.7 mm broad.

Differentiating characters: The new species is more cylindrically shaped and exhibits a greater length to width ratio (> 1.8) than B. kwanti and B. alexpeteri n. sp. (1.6). B. liandinaensis and B. taygetensis n. sp. show the same ratio of about 1.8, but the apex is smaller and not that flat.

Distribution: Only known from type locality in southern Neapoli Pensinsula.
