Differential diagnosis Chersaecia nagaensis differs from C. leiophis in the following traits: shell smaller, spire higher, umbilicus narrower, body whorl rounded (shouldered in leiophis ), periostracum denser, intermediate plica absent, or small and separated from the lamella. Chersaecia goniobathmos is similar to C. nagaensis in shell shape and sculpture, but differs from that species by possessing two lamellae, a long lower plica, and a well-developed intermediate plica, which is in contact with the anterior lamella.
