title: New hemiurid trematodes from deep-sea benthic fishes in the western North Atlantic.
abstract: Eight species of hemiurid trematodes, 6 of which are new, are reported from deep-sea fishes in the Hudson Canyon area of the western North Atlantic. New species include Dinosoma triangulata, D. sulca, Gonocerca haedrichi, G. minuta, Glomericirrus ulmeri, and Pseudolecithaster antimorae. The new genus, Pseudolecithaster, differs from Lecithaster Lühe 1901 by the presence of a sinus organ in Glomericirrus ulmeri sp. n., and G. amadai Yamaguti 1937, the type species, allows emendation of the description of that genus and supression of Glomericirrinae Yamaguti 1958. Gonocerca phycidis Manter 1925 and Lecithophyllum anteroporum Margolis 1958 are reported from new hosts and localities.
