Mandarina is a genus of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Camaenidae, subfamily Bradybaeninae.

Mandarina have been traditionally placed within Camaenidae. Phylogenic study by Chiba (1999) have found, that Mandarina is closely related to Euhadra (family Bradybaenidae) and that Mandarina have probably evolved from Euhadra.

Distribution

The genus Mandarina is endemic to Ogasawara Islands.

Description

The shell is solid. The width of the shell is 15–80 mm.
