Phyllidiella sp. 01 is characterized by its black background colour and numerous grayish tubercles, some of them with whitish apices. The rhinophores are black.
This species was misidentified and posted on 11 July 2003 at these websites as Phyllidiella nigra (van Hasselt, 1824) [Phyllidia], which is an intertidal species and differs by the colour and the size of the tubercles: let me quote Brunckhorst (1993): "The notal tubercles are most commonly single and isolated (although occasionally two or three coalesce), have black bases and, their sides and apices are dark pink to red. Thery are evenly distributed over the dorsum. Individual tubercles are quite tall (up to 3 mm high) with relatively straight sides and a rounded summit. Tubercles around the mantle margin are smaller."
Dr. Richard C. Willan writes (pers. comment) on this species: "It is probably best to call this one simply Phyllidiella sp. It is none of P. nigra, nor P. burni, nor P. pustulosa, nor P. cooraburrama. Sometimes with phyllidiids, like this one, it is impossible to reach an arbitrary identification without morphology or genetics to rely on."
