Brunckhorst, (1993) did not have access to photos of the living colour and pattern of this species.
He notes: "It is probably black and pink (as observed for other Phyllidiopsis species with bicoloured rhinophores)". He also incorrectly describes the rhinophores as pink apically and black basally. Yonow (1988) described this species as having white tubercles on a black background, bicoloured rhinophores and lacking markings on the foot sole, but did not dissect the specimen. The anatomy of the holotype clearly places it in the genus Phyllidiopsis.
Principal distinguishing characters of P. sinaiensis include the tuberculate central ridge, large and multicompound, broad based, pink tubercles (the low tubercles of the holotype are artifacts), and bicoloured rhinophores, black apically and pink basally, with a black band running to the base in the posterior midline. In some specimens, the bases of the tubercles may fuse, leading to a predominately pink dorsum with only a few black lines.
