This undescribed species of flatworm is found under rocks and has a relatively robust body. The animal is cream, with varying degrees of greyish-brown to black patches and spots. It has marginal pseudo-tentacles, with a central circular eye cluster as well as eye clusters around the front margin and tentacles. It is similar in appearance to Thysanozoon brocchii, but is easily distinguished by its lack of dorsal papillae.
