The Confusable Partulina is one of three species from the genus (the other two are Horner's Partulina (Partulina horneri (Baldwin)) as well as the Hawaii Partulina (Partulina physa (Newcomb))), that are resp. were distributed on the island of Hawai'i.

The last sighting of this species (together with Horner's Partulina was in the year 1992, when both species were already mostly restricted to the districts of Hamkua and Kohala.

Subsequent searches were unsuccessful, and the Hawaii Partulina is the only of the three species, that obviously still exists, even if extremely endangered and close to extinction.
