Bythinella kithiraensis View in CoL n. sp. [ fig. 2.8 View Figure 2 ]

Type locality: Greece, Attica, Kithira Island, Mylopotamos , “Valley of the Mills”, tiny spring beside the big waterfall, N 36°14'38.8" / E 22°56'42.0", 275 m a.s.l., 19.10.2019, leg. Hans-Jürgen Hirschfelder. GoogleMaps

Type Material: Holotype ( ZMH 140690 View Materials ): Shell height 2.4 mm, shell width 1.4 mm . Paratypes from type locality: ZMH (140691/1), coll. Hirschfelder (2 adult, 6 subadult) .

Etymology: The new species is named after Kithira Island.

Description:

Shell: The shell is cylindrical with a small and broad flat 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, with a sharp peristome. The umbilicus is closed. The shell is 2.2-2.5 mm high and 1.3-1.4 mm broad.

Differentiating characters: Both Kithiran species are smaller than the species of southern Peloponnese except B. beckmanni . The shell of B. amira n. sp. is in average higher, more conical with a smaller apex than B. kithiraensis n. sp. and the length to width ratio is about 1,9 whereas the latter shows a ratio of about 1.75.

Associated species: Pseudamnicola magdalenae , Gyraulus sp.

Distribution: Only known from type locality in western Kithira Island.

Remarks: This species was not found in the big spring in the center of Mylopotamos.
