Notes compiled from Brunckhorst, 1993:
Phyllidiopsis dautzenbergi is the only member of its genus with large, white semicircles around the margin and a median, longitudinal white area (which may be interrupted). Notal tubercles are small and rounded. Notal spicules are long. Other characteristic features include the white pointed rhinophores, white ventral coloration and pale (white) viscera.
Three other Phyllidiopsis species have black and white coloration. Phyllidiopsis striata differs in having three, low, white dorsal ridges, a white mantle rim and lemon yellow rhinophores. Phyllidiopsis phiphiensis has two, low, white ridges, black spots on the white margin, white rhinophores and black spots on the side of the foot. Phyllidiopsis loricata (Bergh) has a white notum with many small tubercles and dark brown to black spots.
