Deep-sea trawling is concentrated on assessing fisheries, or in fishing; a combination of long hauls and a large mesh size results in a rather poor collection of soft-bodied invertebrates. In this contribution, we report upon the finding of the French-New Zealand Halipro 2 expedition, along the Norfolk and Loyalty Ridges, especially regarding the proposal of a new genus and description of a new species of polynoid polychaetes, Jimipolyeunoa richeri gen. n., sp. n. Jimipolyeunoa has over 50 body segments, with 21 pairs of elytra; it resembles Parapolyeunoa Barnich, Gambi and Fiege (2012), but they differ because in Jimipolyeunoa the prostomium lacks cephalic peaks (present in Parapolyeunoa), and its neurochaetae are unidentate or finely bidentate (clearly bidentate in Parapolyeunoa). Further, a parasitic copepod was found in one of the specimens, and it is described as Herpyllobius pleurotumoris sp. n., being unique by having the right side of ectosoma with single bulging tumour-like process on posterior third, adjacent to genital swellings.
