Notes compiled from Brunckhorst, 1993:
Diagnostic external features of Phyllidiopsis sphingis are: the low white ridges and intervening black stripes mid dorsally; a U-shaped black band around the perimeter of the median area; black rays extending to the mantle edge; iridescent blue coloration on the broad mantle margin; cream to pale yellow rhinophores; cream coloration ventrally; dark grey gills.

This species is superficially similar to Phyllidiopsis annae and Phyllidiopsis striata. However, P. striata has a white mantle skirt without black rays, lemon yellow rhinophores and grey ventral coloration. Phyllidiopsis annae has granular blue, median ridges and mantle margin (white median ridges in P. sphingis) but has neither white coloration, nor black rays on the margin, and possesses black rhinophores with 14-17 lamellae on their clavus (rhinophores cream with 7-10 lamellae on each rhinophoral clavus in the present species). Phyllidiopsis annae has dark grey oral tentacles whereas those of the present species are pale cream.
