Amphidromus sinistralis, common name the sinistral bulimus, is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusc in the family Camaenidae.
The length of the shell attains 37.3 mm, its diameter 18.5 mm.
(Original description) The shell is somewhat acuminately oblong and rather thick, exhibiting a sinistral coiling and being scarcely umbilicated. It comprises seven whorls that appear somewhat rounded and obliquely striated. The columella is reflected, and the aperture is rather small with a reflected outer lip. The shell displays a yellow base color marbled with olive-green, while the interior of the aperture is a very dark brown, and the lip is white.
The type species was found in Java and Sulawesi, Indonesia.
