Subspecies

There are three subspecies recognized:^[2]

• Partula navigatoria levilineata H. E. Crampton, 1956
• Partula navigatoria navigatoria (L. Pfeiffer, 1849)
• Partula navigatoria radiata Pease, 1864

Distribution

This species was endemic to Raʻiātea, French Polynesia, but is now considered extinct in the wild due to predation by introduced rosy wolf snails (Euglandina rosea). It may now be impossible to reestablish this species in its native range, due to the presence of the predatory flatworm Platydemus manokwari which ground-dwelling species such as Partula navigatoria are susceptible to.^[1]
