Abstract
Holorchis castex n. sp. is described from the haemulid fish Diagramma pictum off New Caledonia. It is easily distinguished from all other species in the genus in that the vitellarium reaches well into the forebody. Its relationships with members of the genera Pseudaephnidiogenes and Aephnidiogenes are also discussed. The monorchiid Lasiotocus plectorhynchi is reported from the same host.
