"Nembrotha chamberlaini. According to Pola et al. (2008: 171) the only external difference between Nembrotha chamberlaini and Nembrotha purpureplineata is that Nembrotha chamberlaini has the same uniform red colour on the rhinophores and gills, so this individual has to be Nembrotha chamberlaini. However, given the extent of intraspecific variation in other external colours in Nembrotha purpureolineata, I do find this separation hard to substantiate."
