This species is based on a single specimen. Oval shaped dorid with mantle covered with rounded tubercles. The cenetral part of the mantle is orange-brown, while towards the edge it becomes a palre whitish-orange. There are scattered orange-brown patches on the mantle amongst the rounded tubercles. The larger tubercles have an opaque white basal ring and the tip of each tubercle is pale-orange. The rhinophores are orange, with a pale-cream tip, There are six tripinnate gills. In the description the anterior gills are described as yellowish-cream and the two posterior ones orange, but it is more likely that the gills are like some of the Indo-West Pacific species in which the outside of the gills are whitish and the inside is orange. The mantle underside is whitish, with several brown orange spots on each side of foot. Living animal measured 27 mm in length. This species is named after Hans Bertsch, and his wife Rosa.
