A new species of Bothriembryon (Mollusca Gastropoda Bothriembryontidae) from south-eastern Western Australia

摘要

Bothriembryon sophiarum >sp. n. is described, based on shell and anatomical morphology, from the coastal area of south-easternmost Western Australia. This is the first description of a new extant Australian bothriembryontid in 33 years. The shell of Bothriembryon sophiarum is slender with a unique teleoconch sculpture. It is found in low coastal scrub on cliff edges and escarpments and because of its restricted distribution, qualifies as a short range endemic.
