Bibliographic data :

Rhinophores sheaths and gills bases are blue-purple marginally and yellow submarginally
    The anal papilla is blue

    It lays a bright yellow egg ribbon
    This species have similarity with N. purpureolineata and N. aurea but
            - It differs from N. purpureolineata in lacking the deep red lamellae and purple tips of the rhinophores and having just the edges of the gills red instead of the whole structure
            - It differs from N. aurea. The main colour difference between the two species is that N. aurea has two dorsal orange patches, one in front of the gills and one behind
    Gosliner, Behrens & Williams (1997) report it feeding on the ascidians Clavelina spp., Rhopalaea sp., & Oxycorynia fascicularis .
