Possible colour variants are Chelidonura sp. 01, Chelidonura sp. 02, and Chelidonura sp. 03.
I received on 02 August 2012 an email telling that a PhD student from Mexico (Andrea Zamora) and Manuel Malaquias are working in Bergen on a worldwide revision of the genus Chelidonura, hopefully some of the problems (colour variant or not) will be solved.
More information on Chelidonura sandrana are on Bill Rudman's Sea Slug Forum
Many pictures of colour variants are at NUDIPIXEL!
Pretty similar are:
Chelidonura alexisi which lacks the white marking on the head, and differs by minute white spots,
Chelidonura fulvipunctata which differs by white "W"-shaped mark on the head and
Mariaglaja inornata which differs by a broad white band across the front of the head-shield with a yellow or orange edge to the antero-lateral lobes, and
has the minute white spots only over the outer surface of the parapodia.
