Bythinella alexpeteri View in CoL n. sp. [ fig. 2.5 View Figure 2 ]

Type locality: Greece, Arcadia , Mari, travertine spring at the northern end of the village, N 37°01'58.7" / E 22°49'33.5", 634 m a.s.l., 10.04.2018, leg. Hans-Jürgen Hirschfelder. GoogleMaps

Type Material: Holotype ( ZMH 140684 View Materials ): Shell height 2.9 mm, shell width 1.8 mm . Paratypes from type locality: ZMH (140685/5), coll. Hirschfelder (17 adult, 13 subadult) .

Etymology: The new species is named after Alexander and Peter Reischütz, who figured this species in 2008 for the first time without formal description and compared it with the syntopic Bythinella beckmanni .

Description:

Shell: The shell is ovate cylindrical with a small apex. The 4.5-5 whorls are slightly convex with a deep suture. The body whorl takes about 0.75 of shell height. The aperture is ovate, angled at the top with a sharp peristome, somewhat thickened at the columella. The umbilicus is closed. The shell is 2.6-2.9 mm high and 1.7-1.8 mm broad.

Differentiating characters: The syntopic Bythinella beckmanni Reischütz et al., 2008 , is much smaller (2 mm) and more slender with a less deep suture. B. kwanti is very similar, but the umbilicus is slit-like. The latter species occurs at a distance of 120 km in the Aroania Oros and therefore it seems unlikely that both species are conspecific.

Associated species: Bythinella beckmanni .

Distribution: Only known from type locality in Mari at the southern slope of the Parnon Mountains.

Remarks: The sympatrically occurring Bythinella beckmanni [ fig. 3.5 View Figure 3 ] was not found again in 2018. That species might be extinct as already suspected by Reischütz et al. (2008).
