Remarks.

Only dry shells were found during the surveys. This species is similar to Amphidromus thalassochromus Vermeulen & Junau, 2007 and Amphidromus coeruleus Clench & Archer, 1932 in terms of shell shape and colour pattern on the shell surface. However, it differs from A. thalassochromus by having a rounded last whorl at the periphery and it differs from A. coeruleus in having a somewhat obese shell with a short spire.
