This taxon was described in 1941, as a subspecies of a species that is believed to inhabit the Philippine Islands.

The Palauan Coneuplectra Snail seems to have been restricted to the island of Peleliu in the Palau archipelago, Micronesia.

The snail has not been found alive since 1936; in recent years only some few empty shells have been found and this form very likely is extinct now.

This taxon almost certainly is a distinct species.
