Treatment

Bythinella magdalenae View in CoL n. sp. ( Figs. 20-24 View Figures 20-24 )

Type material: Holotype ( ZMH 140045 View Materials ): Shell height 2.7 mm, shell width 1.7 mm . Paratypes: from type locality Argiroúpoli ( ZMH 140046 View Materials , 3 in ethanol), coll. Glöer (2 in ethanol), coll. Hirschfelder (8 in ethanol, 8 dried); from sampling site 2 Ano Méros ZMH (140047, 1 dried, 2 in ethanol), coll. Hirschfelder (6 in ethanol, 1 dried); from sampling site 3 Axós ( ZMH 140048 View Materials , 1 View Materials penis, 1 dry), coll. Hirschfelder (4 in ethanol, 2 dried), coll. Kittel (11 dried) .

Type locality: Crete, Nómos Réthymnon, Argiroúpoli (14 km SW of Réthymnon), captured spring below the “Church of the Holy Five Virgins”, 35°17’35.2” N, 24°20’33.0” E, alt. 195 m asl., 12.10.2014 Andrea and Hans-Jürgen Hirschfelder, Klaus Kittel leg. ( Fig. 32 View Figs ); B. sitiensis n. sp. feeds on fallen leaves of Platanus orientalis .

Etymology: The new species is named in honour of Magdalena Szarowska (Kraków, Poland). She was the first who recognized a greater diversity in the genus Bythinella on Crete.

S ampling site 2 (Paratypes): Crete, Nómos Réthymnon, Ano Méros (25 km SW of Réthymnon), captured spring 2, 9 km NW of Ano Méros along the road to Gerakári , 19.04.2016 Andrea and Hans-Jürgen Hirschfelder. B. magdalenae lives only in a small outflow beside the main source ( Fig. 33 View Figs ) .

S ampling site 3 (Paratypes): Crete, Nómos Réthymnon, Axós (33 km E of Réthymno), spring 500 m W of the village along the road to Enagron Ecotourism Village , 35°18’37.4” N, 24°50’14.0” E, alt. 430 m asl., 03.05.2016 Hans-Jürgen Hirschfelder, Theresia Kittel leg. ( Fig. 34 View Figs ); together with Melanopsis buccinoidea GoogleMaps .

Description:

Shell: The shell is cylindrical with a small apex. The 4-4.5 whorls are slightly convex with a deep suture. The aperture is ovate, narrowed at the top, with a sharp peristome. The umbilicus is slit-like. The shell is 2.7-2.9 mm high, 1.7-1.8 mm broad.

Animal: The penis is as long as the penial appendix. The tubular gland has the same width over the full length.

Additional material: B. magdalenae n. sp. probably also lives in the spring of Spíli (see above under Pseudamnicola occulta n. sp.). The collected specimens correspond with the type series but are not treated as paratypes because only dry material could be collected and no anatomical investigation was made.

Distribution: Central part of Crete.

Remarks: For discussion see under Bythinella sitiensis n. sp.
