). The oral tentacles are white and have four yellow tips each. The dorsum has, on each lateral margin, ten short papillae with yellow pigmentation on the apex. All over the dorsum there is a network of spicules. The rhinophores are white, non-retractile, and ringed with 18 lamellae. There are 11 unipinnate (the largest one is bipinnate) branchial leaves white in colour, having the rachis yellow (in the distal region edged with two red lines). The tail has a yellow line in the centre with few red spots.

, as being a white animal with three crimson lines on the dorsum, which joined together in the anterior part, and a crimson patch on the anal area. The dorsal papillae were reddish and yellow, the branchial leaves had a crimson colour, and the rhinophores were yellow. Our specimen, as well as Bergh’s, has a white background colour, red and yellow pigmentation on the lateral papillae, and the branchial leaves are also reddish (with two red lines). However, our specimen shows a few differences in colour pattern from Bergh’s material (white rhinophores instead of yellow, white branchial leaves instead of crimson), and with that described by
