The sea slug Chromodoris kuniei is one of a group of similarly coloured species which Bill Rudman calls the "Risbecia tryoni colour group". They all have large purple or purple-brown spots or marks, usually ringed with white, an often reticulate brownish background, and a purple border:
Chromodoris geminus which has four colour bands around the mantle edge: an outermost white, then translucent greyish purple, then white, then yellow. It has a wide mantle overlap.
Chromodoris leopardus which has leopard-like multiple spots, or marks, forming a hollow squarea, distinct purple line at the border of the mantle and a wide mantle overlap.
Risbecia tryoni which has high shape of the body with a reduced mantle overlap.
Showing the characteristic mantle waving behaviour of this species, in which all the mantle edge is raised and lowered together.
