Distribution.

Known from upper Kinta Valley and Perak River valley, Perak only ( Maassen 2001).

Remarks.

Shell dextral. Smallest shell of all congeners. Also differ from congeners by the peristome that is reflected and thickened multiple times, sharply angular at the base of the columella and slightly angular at the upper outer lip ( Laidlaw 1949). Davison (1991) considers D. crosseana as possibly related to Diplommatina maduana Laidlaw, 1949.
