Cratera aureomaculata is a medium-sized land planarian with an elongate body with parallel margins and slightly convex dorsal surface.

The dorsum has a yellow background that is covered by brown pigmentation in the anterior region.

There are blackish pigmentation forming irregular flecks over the dorsal surface, being larger laterally and becoming more concentrates towards the posterior tip.

[1] Aside from coloration, C. aureomaculata is distinguished from other members of the genus Cratera by having clear halos of its eyes, a cylindrical pharynx, a T-shaped, ventrally displaced prostatic vesicle, and a conical penis papilla that is symmetrical with the ventral insertion.

[1] Cratera aureomaculata is known only from the Três Barras National Forest, Santa Catarina, Brazil.
