Partula navigatoria is a species of air-breathing, ground-dwelling ^[1] tropical land snail in the family Partulidae. ^[2] This species has been extinct in the wild since the year 1992. ^[1]

Subspecies

There are three subspecies recognized: ^[2]

• Partula navigatoria levilineataH. E. Crampton, 1956
• Partula navigatoria navigatoria(L. Pfeiffer, 1849)
• Partula navigatoria radiataPease, 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]
