Mandarina Explained

Mandarina is a genus of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Camaenidae, subfamily Bradybaeninae.^[1]

Mandarina have been traditionally placed within Camaenidae.^[2] Phylogenic study by Chiba (1999)^[3] 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]
