Lamiopsis tephrodes	*Lamiopsis temminckii*
Upper teeth triangular in shape, both margins symmetrical. Distal and mesial shoulders mildly pronounced	Upper teeth more cordiform in shape, tapering just below basal ledge. Distal mesial shoulders very pronounced
Posterior molariform teeth in upper jaw relatively few. Generally 3–5 rows	Posterior molariform teeth in upper jaw more numerous in count. Generally 5–7 rows
Upper lateral and posterior teeth noticeably oblique with convex mesial margins	Upper lateral and posterior teeth relatively straight with mesial margins slightly angular but rarely convex
Serrations on upper teeth usually coarser basally on shoulders, descending to much finer serrations towards apex.	Serrations more evenly distributed, and not noticeably coarser basally
Serrations generally coarse in upper teeth of adults	Serrations generally finer in upper teeth of adults
Lower teeth sometimes with very finely serrated cutting edges in adults	Lower teeth with entirely smooth cutting edge
