Posterior portion of the body has alternating bands of light and dark pigment, while the middle and anterior of the body is characterized by discrete light and dark patches of pigment. Rhinophores are thick, club-shaped with about eight lamellae and a pointed tip. The small gill has a central, branching stalk flanked by two smaller branches. The extra-branchial and extra-rhinophoral appendages are thick, stocky and have a slight bulge near the base. The anterior margins of the foot extend laterally as elongate appendages. Oral tentacles are short. Posterior foot is bluntly rounded and less pointed than typical of Trapania.
