There are many similar coloured chromodorids which Bill Rudman calls the "Chromodoris quadricolor colour group" of species characterized by black longitudinal lines, bluish backgrounds and orange borders.
Chromodoris sp. 06 is a large Chromodorid, the above specimen was 6.5 cm long. It has a white body, a broad median longitudinal black band and a broad black submarginal band encircles the rhinophores and gills. Both bands are outlined by diffuse dark gray (looking like a shadow). It has an orange marginal band. The rhinophores and gills are orange.
The photographer Gordon Tillen writes:"The overall opinion at the workshop was Chromodoris sp."
Very similar is Chromodoris magnifica (Quoy & Gaimard, 1832) which is usually 'smaller' and differs by a thin white marginal band, and has no black submarginal band on the head, the band is broken in front of the rhinophores.
This species might be a dark colour form of Chromodoris sp. 05  Genus: Alder & Hancock, 1855, I keep them seperate for now.
