Subspecies

A number of subspecies were recognised; Placostylus bollonsi arbutus and P. b. bollonsi are classified by the New Zealand Department of Conservation as being Nationally Endangered, while Placostylus bollonsi caperatus is classified as Nationally Critical.[3]

Buckley et al. (2011)[4] found based on molecular phylogeny research and shell morphology research, that there are no subspecies of Placostylus bollonsi.[4]
