There are many problematical yellow-spotted species of Chelidonura which still need to be sorted out. One I have not mentioned before is Chelidonura castanea Yonow 1994, which was described from the Maldives as brownish with yellow spots and with white edging to the parapodia and the head shield. It is possiblya synonym of C. punctata, but Yonow specifically says the background is not black..
Chelidonura tsurugensis has 2 white marks on the head but it differs in having no yellow spots ventrally. Other possiblilties are Chelidonura sp. 2, but as I discuss under Chelidonura sp. 6 we still need to know a lot more about colour variation within individual species.Authorship details
