Holotype

(NMB 11517a): shell height 7.5 mm, width 5.6 mm.

Paratypes.

Mazandaran Province, Tschalekuti (NMB 11517a, 26 ex.), Geniste d. Babul (NMB 11517b, 1 ex., NMB 11571c, 10 ex.)

Etymology.

Named after Lothar Forcart in appreciation on his studies of Iranian freshwater snails.

Description.

The whitish shell is conical with 5.5 whorls, which are convex with a deep suture and a small and acute apex. The convex whorls are flattened at the suture. The umbilicus is open. The aperture is ovate, angled at the top. The margin of the aperture is, from lateral view, slightly sinuated. The surface is smooth with fine growth lines. Shell height 5.5 - 7.5 mm, width 5.0 - 5.6 mm.

Differentiating features.

Due to theshape of the aperture (angled at the top), Bithynia forcarti sp. n. resembles Bithynia mazandaranensis sp. n. (see below). However, from the latter species it can be easily distinguished by the stepped whorls.

Remarks.

Formerly ( Forcart 1935) this species has been confused with Bithynia tentaculata .
