Oahu Tree Snail (Achatinella pupukanioe)

This species was described in 1914.

The shells reach sizes of about 1,6 cm in height; they are glossy white or ivory yellow with a white sutural line, or either of these tints with a burnt sienna band immediately above a wider and darker band. [1]

The species was last found in 1980 in the forest along the Aiea Ridge Trail in the Ko’olau Mountains; it is now most likely extinct. [1]
