Remarks.

This is a new record for Penang Hill. The shell spire is moderately raised. Teleoconch with densely spirally arranged pits above periphery, transitioning to densely placed spiral grooves on the subsequent whorls, which become more densely placed towards the periphery. Below periphery with densely placed spiral grooves that continue from the upper shell and fade away towards the umbilicus. The shell sculptures of this species are similar to Microcystina Penang sp. 6 , but it differs by having a smaller shell size, only half the size of Microcystina Penang sp. 6 .
