Feeding Porites compressa infected with a digenean metacercaria to the coral-feeding butterflyfish, Chaetodon multicinctus, established that the metacercaria was Podocotyloides stenometra. Those and field examinations finding a prevalence of 100% and an average intensity of infection of 6.5 worms/fish in 28 C. multicinctus off Kaneohe Bay, Oahu, Hawaii, established this fish as a definitive host. Plagioporus sp. of Cheng and Wong, 1974 is a synonym of P. stenometra.
