Three opisthomonorchiinae species are described from fishes obtained at the Fish Market in Nouméa, New Caledonia. Opisthomonorchis dinema n. sp. from Carangoides dinema Bleeker differs from the other recognised species in the genus by the long recurved genital atrium, arcing anteriorly. Also described are Opisthomonorchis carangis Yamaguti, 1952 from Carangoides sp. and Pseudopisthomonorchis thapari (Varma & Singh, 1979) n. comb. for Opisthomonorchis thapari Varma & Singh, 1979 from Carangoides chrysophrys (Cuvier).
