Notes compiled from Brunckhorst, 1993:
Phyllidiella cooraburrama is a particularly striking nudibranch. It is distinguished by its extremely large, isolated, notal tubercles which have a very broad pink base, are steep sided, tall and multicompound with flattish (sometimes rounded) apices. P. cooraburrama is easily separated from its pink congeners by the form of its large tubercles. Phyllidiella pustulosa has grouped clusters of low tubercles. Phyllidiella annulata has rings of pink with low angular tubercles. Phyllidiella nigra has single rounded red-pink tubercles. Phyllidiella rosans has low, rounded, smooth, straight ridges. Phyllidiella zeylanica has highly tuberculate ridges which join together anteriorly and posteriorly. Phyllidiella granulata is superficially similar to P. cooraburrama, but differs in having smaller conical or acute white tubercles on a granular grey background.
