Although seemingly quite different from Chromodoris striatella I have seen animals in New Caledonia, both lined and spotted living together, and occasionally with an intermediate pattern in which some of the rows of spots are joined to form partial black and orange lines. If you look at the photo of an almost 'unlined' colour form, the same two pale patches, one in front of the gills, the other behind the rhinophores, can be seen. No major anatomical differences have been found.

It is probable that the recently described Chromodoris mandapamensis is a dark example of this same colour form. See also a photo of an intermediate with lines and spots.
