Partulina virgulata[3] is a species of tropical air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Achatinellidae. This species is endemic to Hawaii in the United States.[4]

Description

The shell of Partulina virgulata is of a light tan color with dark brown bands and a lighter whorl that goes from plum-colored to a white shade.[5] Malacologist Dilev D. Thaanum has recorded 1,067 organisms of this species.[5] He has found that 1,053 of those mollusks have a sinistral shell, which indicates that the majority of the species are configured with the opening of the shell to the left[5] which is rare for most gastropod species.[6] The species is also less likely to reproduce often.[2]

Distribution and habitat

Partulina virgulata is endemic to the island of Moloka’i[4], from the northern side near Pelekunu or valleys near Kamalo to the eastern side of the island.[5] It is mostly found on native plants and shrubs.[5]
