Some trypanorhynch cestodes from Hawaiian fishes, with descriptions of four new species.

Examination of teleost and elasmobranch fishes for cestodes from the Pacific Ocean off the Hawaiian Islands resulted in the recovery of 7 species of trypanorhynchs, 4 of which are new. The new species are Pseudogrillotia basipunctata, Pterobothrium hawaiiensis, Prochristianella micracantha, and Nybelinia basimegacantha. Tentacularia coryphaena Bosc 1797, Dasyrhynchus giganteus (Diesing 1859), and Parachristianella monomegacantha Kruse 1959 represent new host and distribution records. The family Pseudogrillotidae Dollfus 1969 is emended.
