Opeas brevispira Pilsbry & Y. Hirase, 1904 (original combination) Allopeas brevispira is a species of small, tropical, air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Achatinidae.

(Original description) The shell is openly perforate and oblong, notably short for the genus.

It has a corneous, translucent, and glossy surface, finely striated with wrinkles.

The aperture is elongated and rhombic-convex, with the outer lip arched forward in the middle.

The columellar lip is reflexed, only adhering at the point of insertion, while the columella remains straight.
