Remarks.
According to MolluscaBase, this is a "Taxon inquirendum". This species was placed as junior synonym of Dyakia regalis (Benson, 1850) by Laidlaw (1963). However, the shells from Bau are different from Dyakia regalis (Benson, 1850) in having a straw-yellow to light brown shell with a shiny surface below the periphery.
