Galea, Horia R., Maggioni, Davide (2020): Plumularioid hydroids (Cnidaria: Hydrozoa) from off New Caledonia collected during KANACONO and KANADEEP expeditions of the French Tropical Deep-Sea Benthos Program. European Journal of Taxonomy 708: 1-58, DOI: 10.5852/ejt.2020.708
Remarks The specimens at hand conform strictly to the original description by Vervoort & Watson (2003). However, no mention was made by these authors as to the occurrence of pseudophylactocarps, as noted in the present specimens (Fig. 2 F – H). These ca 5 mm long, curled structures replace some hydrocladia either on the proximal parts of side branches or on the main stem before it branches; like the cladia, the pseudophylactocarps are borne on the same apophyses, and are composed of a succession of short internodes that possibly represent vestigial hydrothecae, together with their corresponding mesial nematothecae.
