Diplectanum parvus sp. nov. is described from the coral reef fish Cephalopholis urodeta collected off New Caledonia, South Pacific, and is the first diplectanid described from this fish. The new species has a very small male copulatory organ (24 μm in length) and a minute body (246 μm in length) and is close to D. nanus Justine, 2007 from which it can be distinguished by the shape of dorsal bars and various measurements. These species belong to a group of diplectanids found in groupers (Serranidae, Epinephelinae), characterised by small funnel-shaped male copulatory organs and no sclerotized female organs. The attribution of these parasites to Diplectanum Diesing is provisional. Other parasites are briefly listed.


Diplectanum parvus sp. nov. est décrit du poisson de récif corallien Cephalopholis urodeta pLché en Nouvelle-Calédonie, et est le premier Diplectanidae décrit de ce poisson. La nouvelle espèce a une organe copulateur mâle (long de 24 μm) et un corps (long de 246 μm) très petits et est proche de D. nanus Justine, 2007 dont elle peut eêtre différenciée par la forme des barres dorsales et diverses mesures. Ces espèces appartiennent B un groupe de Diplectanidae parasites de mérous (Serranidae, Epinephelinae), caractérisés par des organes copulateurs mâles petits en forme d’entonnoir et l’absence d’organes sclérifiés femelles, qui sont attribués provisoirement B Diplectanum Diesing. Les autres parasites sont brièvement mentionnés.
