Phyllidiopsis burni is characterized by black rhinophores, the tapering of the body anteriorly and posteriorly, a black background coloration of the mantle, deep pink multicompound tubercles and a pale pink mantle edge.
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): "Good try at identifying them, but only those from very shallow water (0 - 3 m) are true Phyllidiella nigra. That species has few, large, very rounded (usually solitary) pustules. All the ones you posted from deeper water (greater than 10 m) are Phyllidiella burni - it has more numerous, smaller, usually multicompound and angled pustules.
