Treatment

Diplommatina crosseana Godwin-Austen & Nevill, 1879 Figure 9D View Figure 9

Materials examined.

Prk 47 Kanthan: BOR/MOL 9087. mykarst-184 Bat Cave: BOR/MOL 9850. mykarst-027: BOR/MOL 9021.

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.
