This rather featureless species resembles the native Obtusella intersecta (Wood, 1857), which differs in being still more pupoid with blunt top, in being more umbilicate and brownish in color; Obtusella species are found rather deep on the shelf. Other native species belonging to the genus Setia are smooth, usually translucent with a color pattern of brown blotches.
