Camallanus carangis Olsen, 1954 (Nematoda: Camallanidae) reported from French Polynesia and Hawai'i with a redescription of the species.

The marine fish parasite Camallanus carangis Olsen, 1954 (Nematoda: Camallanidae) is redescribed from the honeycomb grouper Epinephelus merra (Serranidae) in the Tuamotu Islands of French Polynesia and the glasseye Heteropriacanthus cruentatus (Priacanthidae) in Hawai'i, both coral reef fishes. Camallanus carangis is reported for the first time from French Polynesia and Hawai'i. Camallanus marinus Schmidt and Kuntz, 1969 is designated a synonym of C. carangis and Camallanus paracarangis Velasquez, 1980 is regarded as a species inquirenda. Additionally, the genus Oncophora may need to be redefined to accommodate Camallanus aotea Slankis and Korotaeva, 1974, which bears more resemblance to Oncophora than Camallanus.
