Pretty similar are:
Chelidonura alexisi which lacks the white marking on the head,
Chelidonura sandrana which lacks the white "W"-shaped mark on the head and has usually white and orange spots,
Chelidonura 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.
