Popis: Pseudamnicola thawintae sp. n. (Figs 2–8) Type material: holotype: 2.75 mm high and 1.8 mm broad, ZMH 140882. Paratypes: 30 specimens from type locality: 3 sp. ZMH 140883, 14 in coll. Glöer, 13 in coll. Sadouk. Type locality: Tizi-Ouzou region (North-central part of Algeria), 36°30’21” N 4°02’28”E, at an altitude of 720 m. Habitat: a marshy environment, rich in vegetation and shady (Fig. 1). Etymology: Named after the locality where the species lives. Description: The ovate shell has 3.5–4.0 slightly convex whorls separated by a deep suture. The aperture is ovate with a sharp peristome. The umbilicus is closed. The outer lip is straight from lateral view. The juveniles are more globular than the adults. The shell is 2.4–2.8 mm high and 1.7–1.8 mm broad. The mantle is black pigmented. The penis is triangular with a broad blunt penis tip. The females have not been investigated. Differentiating features: The shells of Pseudamnicola spp. from Algeria which are of similar size as P. thawintae sp. n. are more globular than P. dupotetiana (Forbes, 1838) or their apertures are triangular like P. meluzzi (Boeters, 1976) and P. chabii (Glöer, Bouzid et Boeters 2010). Other species have stepped whorls like P. gerhardfalkneri (Glöer, Bouzid et Boeters 2010) or P. calamensis (Glöer, Bouzid et Boeters 2010), or P. linae (Glöer, Bouzid et Boeters 2010), or P. letourneuxiana (Bourguignat, 1862) (see fig. 30 in GLÖER et al. 2010), as well the other species are markedly larger, P. luteola (Küster, 1852) 4.5–5 mm, P. constantinae (Letourneux, 1870) up to 4.1 mm, P. fineti Glöer, Bouzid et Boeters 2010 between 3.5 and 3.9 mm. Ecology: The marsh is located in a scrubland of the Ait Bouadou region (Kabylia, Algeria). The marsh is narrow, approximately 1–1.5 meters deep and 2 meters wide. The sample site is near a stream characterized by a very dense herbaceous and shrub layer and very wet soil. The species is found on the edges of this marsh. Distribution: Only known from the type locality.
