A new subspecies of Amphidromus palaceus (Mousson, 1849) from Sukabumi Regency, West Java, Indonesia

Abstract

This paper describes a new subspecies of Amphidromus palaceus (Mousson 1849b) from Nyalindung, West Java, Indonesia. Both subspecies have a similar animal coloration andproduce dextral or sinistral shells. The shell of the new subspecies differs from nominotypical A. palaceus by having pale-colored stripes marking resting stages, lack of brown subsutural spots or blotches and the presence of a smoother sculpture, less recurved lip margin and thicker white parietal callus.
