Remarks.
This is a new record for Penang Hill. The shell spire is highly raised, with a height more than half of the last whorl height. This species has the most convex shell compared to other Microcystina species from Penang Hill. On the upper shell, the apical whorls have elevated spiral ribs that continue onto subsequent whorls, which are crossed by radial ribs forming granule-like sculptures. Below the shell, there are spaced grooves with spiral lines at the periphery, which reduce towards the umbilicus.
