Remarks.

This is a new record for Penang Hill. This species differs from L. trochoides by having more, less prominent spiral ribs, and from L. striolatus by having more spiral ribs. It also differs from L. garelli ( Souleyet, 1852) , which was previously recorded and described from Penang, by having more rapidly expanding whorl size.
