Pommerhelix stanisici n. sp. is currently known from a single small rock outcrop, just off the side of the road. The actual size of the population is unknown but it is probably not large. There are other rock outcrops in the surrounding area which have not as yet been surveyed for snails, and it is likely that other populations await discovery. Pommerhelix stanisici is most similar to P. exocarpi in shell shape, but can be distinguished by its generally larger size and more rounded body whorl. It can be differentiated from most other members of the genus by is low spire and open umbilicus.

Pommerhelix stanisici n. sp. is only known from the type locality, where it was found amongst rocks. Type material. Pommerhelix stanisici n. sp., Holotype, QM M072371, paratypes QM M044726. Type locatity. 3.6 km W. along Hill End Rd, from junction of Hill End & Peel Rds, W. of Sofala, New South Wales, Australia
