Mandarina is a genus of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Camaenidae, subfamily Bradybaeninae. ^[3]

Mandarina have been traditionally placed within Camaenidae. ^[2] Phylogenic study by Chiba (1999) ^[4] have found, that Mandarina is closely related to Euhadra (family Bradybaenidae) and that Mandarina have probably evolved from Euhadra. ^[2]

Distribution

The genus Mandarina is endemic to Ogasawara Islands. ^[2]

Description

The shell is solid. ^[2] The width of the shell is 15–80 mm. ^[2]

Species within the genus Mandarina include:

• Mandarina anijimana ^[2]
• Mandarina aureola ^[2]
• Mandarina chichijimana ^[2]

• Mandarina luhuana
• Mandarina mandarina ^[2]
• Mandarina polita ^[2]
• Mandarina ponderosa ^[2]

Ecology

Mandarina live in various habitats including arboreal, semi-arboreal, ground habitats, wet habitats and dry habitats. ^[2]
