Remarks :

Identification confirmed by Hsini Lin and Nathalie Yonow
    This species was known as Noumea simplex (Pease, 1871) [ Chromodoris ]. The discovery by Rüdiger Bieler that the generic name Noumea was first introduced by Fauvel (1874) for a beetle means that the subsequent introduction by Risbec (1928) for a nudibranch is invalid. Therefore the next available generic name has to be used for the genus of nudibranchs, and that is Verconia   Pruvot-Fol, 1931.
    Synonymous : (according Worms)
            - Chromodoris simplex Pease, 1871 (original combinaison)
            - Noumea simplex (Pease, 1871)
