Type locality.
"SGR 01 Batu Caves, Selangor (3°14'17"N, 101°41'02"E)".
Remarks.
This taxon differs from S. kapayanensis in the larger shell, more expanded body whorl, thicker operculum, and the formation of the upper palatal section of the peristome. These differences seem to justify differentiation at the subspecific level only.
