Originally described from Indonesia, and occurring from East Africa to the Great Barrier Reef (personal observations) Gosliner's photograph of a specimen from South Africa (as P. nigropunctatus) is the only other published record of this species. Externally it is easily recognised by the regularly arranged triangular white marks on the inside of dark brown tubercles. The tip of the white triangles point towards the mantle edge. This shading gives the spots the appearance of raised white pointed papillae.
See Pleurobranchus atlanticus which is possibly an Atlantic 'form' or 'sibling species'.
