Sclerodoris rubicunda (Baba, 1949)

Dr. Kikutaro Baba originally described this species as a Halgerda, because to the ridges on the notum. It has since been moved to Sclerodoris because tubercles have caryophyllidia, which are microscopic organs composed of spicules surrounding a central knob covered with cilia.

Sclerodoris rubicunda is redish-orange with a large, irregular opaque band across the dorsum and on the head between the rhinophores. The series of notal depressions gives this species a sponge-like appearance, which makes it quite cryptic on the red sponge it feeds on.
