Pseudopycnadena tendu sp. nov. is described from the balistid Pseudobalistes fuscus from the waters off New Caledonia. It differs from the only other member of the genus P. fischthali Saad-Fares et Maillard, 1986, in its broad cirrus-sac, with the wide field of large gland-cells, its less nearly circular body shape, its dorsal excretory pore, its shorter post-testicular region, its relatively larger ventral sucker and its smaller eggs. The genus is re-defined to take these distinctions into account. Other opecoelid species reported from New Caledonia are Allopodocotyle epinepheli (Yamaguti, 1942) from Epinephelus cyanopodus, E. fasciatus and E. merra, Cainocreadium epinepheli (Yamaguti, 1934) from E. coeruleopunctatus, E. fasciatus and Variola louti, Hamacreadium mutabile (Linton, 1910) from Lutjanus fulviflamma and L. kasmira, Helicometra epinepheli Yamaguti, 1934 from E. fasciatus and E. merra, Orthodena tropica Durio et Manter, 1968 from Lethrinus lentjan, Pacificreadium serrani (Nagaty et Abdel-Aal, 1962) from Plectropomus leopardus and Pseudoplagioporus interruptus Durio et Manter, 1968 from Lethrinus rubrioperculatus.

Pseudopycnadena tendu sp. nov. est décrit du baliste Pseudobalistes fuscus pêché en Nouvelle-Calédonie. L’espèce diffère du seul autre membre du genre, P. fischthali Saad-Fares et Maillard, 1986, par son sac du cirre plus épais avec un champ large de cellules glandulaires, sa forme du corps presque circulaire, son pore excréteur dorsal, sa partie post-testiculaire plus courte, sa ventouse ventrale relativement plus grande et ses œufs plus petits. Le genre est redéfini pour prendre en compte ces distinctions. D’autres Opecoelidae sont mentionnés de Nouvelle-Calédonie: Allopodocotyle epinepheli (Yamaguti, 1942) de Epinephelus cyanopodus, E. fasciatus et E. merra, Cainocreadium epinepheli (Yamaguti, 1934) de E. coeruleopunctatus, E. fasciatus et Variola louti, Hamacreadium mutabile (Linton, 1910) de Lutjanus fulviflamma et L. kasmira, Helicometra epinepheli Yamaguti, 1934 de E. fasciatus et E. merra, Orthodena tropica Durio et Manter, 1968 de Lethrinus lentjan, Pacificreadium serrani (Nagaty et Abdel-Aal, 1962) de Plectropomus leopardus et Pseudoplagioporus interruptus Durio et Manter, 1968 de Lethrinus rubrioperculatus.
