This animal coexists with Ercolania boodleae in high intertidal rock pools. The species is pigmented black. One of the key characters is that the sole of the foot is yellowish white with two longitudinal black bands extending the length of the foot; another species (Aplysiopsis toyamana) has two longitudinal black bands that extend from tail to center of foot (Baba 1959). We found 6 specimens on 16 May 2000 on the Miura Peninsula, Japan; our specimens were up to 13 mm long. Gonor (1961) distinguished Aplysiopsis enteromorphae (as Hermaeina smithi) from A. minor and other congeners.
