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.
This paper describes a new subspecies of Asperitas bimaensis (Mousson, 1849) from Alas District, western Sumbawa in West Nusa Tenggara, Indonesia. Shell coloration, pattern, sculpture, shape and periostracum separate it from the other subspsecies of A. bimaensis, and a similar looking relative from western Sumbawa.
The following are corrections to the gender assignment of recently published names of two snails from Indonesia. The names as originally published by Parsons (2019a, b) are Asperitas bimaensis abbasianus Parsons, 2019 from western Sumbawa and Papuina abbasianus Parsons, 2019 from Nabire, Papua. The corrected names are Asperitas bimaensis abbasiana and Papuina abbasiana.
