sp. n.

Acroloxus pseudolacustris   ZBK   sp. n. Fig. 15a-b View Figure 15

Type locality.

Gilan Province, IR82-05, Bandar Anzali Lagoon, 49°27'E, 37°26'N, 16 June 2008.


(ZMH 79378): Shell length 4.0 mm, width 2.0 mm, height 0.9 mm.


2 ex., NMB 11516a " Acroloxus lacustris   " zwischen Nika und Aschref, 10 m ü. M., Drs. A. Erni & R. Buxtorf leg. 22.X.1931.


Named for its resemblance with Acroloxus lacustris   .


The oval limpet shell is transparent. The apex is blunt and bent to the left side ( Figs 15a-b View Figure 15 ).

Differentiating features.

The new species resembles Acroloxus lacustris   , which can be easily distinguished by the shape of apex, which is always acute and not blunt ( Figs 15c-d View Figure 15 ) like in the new species. From Russia, no Acroloxus   sp. with a blunt apex is known (Vinarski, pers. comm.).


An analysis of the two specimens from Forcart’s collection (NMB 11516a) identified as Acroloxus lacustris   from Mazandaran Province shows that these specimens belong to Acroloxus pseudolacustris   sp. n.

Associated species.

Haitia acuta   .


Iran: Gilan and Mazandaran Provinces.
