Maui and Oahu.
Taxonomic notes: Kay, 1979 lists Pilsbry's Odostomia seconda as a synonym of Nesiodostomia montforti Corgan, 1972. However, Severns, 2011, illustrates the latter species as Eulimella secunda while including a shell that is probably an Odostomia cf. oxia under the name Odostomia montforti Corgan, 1971. Corgan proposed the name N. montforti as a replacement for Odostomia secunda. The shell labelled Nesiodostomia montforti in Kay, 1979 is probably a worn specimen of that species.
