Glöer, Peter, Stefanov, Tihomir & Georgiev, Dilian, 2018, A new Pseudamnicola (Gastropoda: Hydrobiidae) from the Island of Limnos (Greece), Ecologica Montenegrina 19, pp. 159-162 : 160-161

Pseudamnicola limnosensis n. sp.

Type materials: Holotype: shell height 3.0 mm, width 2.1 mm, spire height 0.6 mm ( ZMH 87634 ); paratypes: 2 adult specimens, 1 juv., 1 embryonic shell, 2 empty shells ( ZMH 87635 ), and 2 specimens in coll. Glöer.

Type locality: Limnos island , Greece, small well near Katalakko village, N39.962662 E25.139903, 89 m a.s.l. 01.- 10.09.2017, T. Stefanov leg.

Etymology: Named after the name of the island where the species was found.

Description: The corneous shell is silky, ovate conical to globular, with a prominent body whorl and a pointed apex. The 4 whorls are slightly convex with a deep suture. The lateral line is slightly convex. The aperture is ovate, the peristome is thickened, the umbilicus is slit-like. The shell is 2.5-3.0 mm high and 1.9- 2.2 mm broad, the spire height is 0.5-0.6 mm.

Differentiating characters: The only difference to the other Pseudamnicola spp. of the region lies in shell proportions: P. limnosensis n. sp. is broader than the other species and the spire compared to most of the other species is higher.

Anatomy: Penis broad and triangular, female sex tract unknown.

Habitat and Ecology: The specimens have been collected from a small well with flowing water in the NW part of the island, W of Katalakko village. The water was flowing first to a concrete hod and then to the ground. The snails were collected from the small waterbody formed around the well. This was the only flowing fresh water in this part of Limnos Island. The well was situated in sandy, dry, barren landscape with grass vegetation on a NW slope of a small hill (340 m a. s. l.). Valley of a small river was crossing the landscape in the area, which was dry in the time of sampling.

Distribution: Only known from type locality.
