Description
Mantle elongate with a wide overlap. Ground colour white, with an irregular-width purple marginal border (sometimes broken or reduced to spots). Inside this is a broad white region scattered with bright yellow spots and larger dark purple spots. A large translucent reddish to orange-brown patch occupies the central dorsum from in front of the rhinophores to behind the gills, sprinkled with fine white specks. Rhinophore stalk translucent, club dark reddish-brown with a white tip and white-specked lamellae. Gills sub-quadrangular, translucent with a dark brown to almost black line running down each edge. Foot white with a row of bright yellow spots all around the edge. Reaches 80 mm in body length.Distribution
Type locality is La Perouse, Botany Bay, Sydney, NSW, Australia (sublittoral, December 1976). The original description (Rudman, 1987) records the species from southern Queensland, NSW (Sydney Harbour, Botany Bay), the Solomon Islands (Guadalcanal), and Hong Kong. Subsequent records extend to New Caledonia, Papua New Guinea, Indonesia, Malaysia, China, and Japan.Etymology
The specific epithet collingwoodi honours Cuthbert Collingwood (1826-1908), the English naturalist who collected nudibranchs in the South China Sea in the latter half of the 19th century. Rudman remarks in the original description that, although Collingwood's 1881 descriptions are based solely on external features, they are accurate and exemplary even by modern standards, and far surpass the work of more prolific contemporaries.Remarks
Material previously identified as Chromodoris aureopurpurea by Thompson 1972 and Willan & Coleman 1984 belongs to this species, which Rudman 1987 separated from the true Chromodoris aureopurpurea Collingwood, 1881. Closest in pattern to Goniobranchus tennentanus, but Goniobranchus tennentanus has each purple spot ringed in white and the purple spots restricted to the central orange-brown patch.References
