Chromodoris aureopurpurea Collingwood, 1881
Chromodoris aureopurpurea was originally described from the coast of China. It's distribution is now documented throughout the tropical western Pacific, to New Caledonia, Australia and Indonesia.
The species which grows to a little over 40 mm in length, is white with small diffuse brown patches and yellow spots over the central dorsum. The margin is distinct, bearing a band of diffuse purple, broken by larger deep purple spots. In some specimens there are yellow spots on the inside edge of the large purple spots. The rhinophores and gills are purple to red-brown with white edge.
When identifying this species, it should not be confused with other species
having purple marginal spots - Chromodoris rufomaculata (the photo in
Nudibranchs and Sea Snails. Indo-Pacific Field Guide by Debelius is actually a C. aureopurpurea) and C. alius, both of which
have purple marginal spots. In these two species, the spots are right on
the edge of the mantle however. A handsome photo of C. alius can be found
on Bill Rudman's Sea Slug Forum . Also similar,are Chromodoris collingwoodi (the center of the dorsum in this species is
deep reddish brown, with white specks), and C. tennentana from the Indian
Ocean. In the latter, the central portion of the dorsum is brown with large
