In order to clarify the systematic position of some opecoeline digeneans parasitic in scorpaenid and gadid fishes from the northern North Atlantic, a study of the genera Anomalotrema Zhukov, 1957, Pellamyzon Montgomery, 1957, and Opecoelina Manter, 1934, was carried out. Anomalotrema is retained in the subfamily Opecoelinae and A. koiae sp. nov. is described for the worms from scorpaenids and gadids which prompted the investigation. This species is distinguished from the Pacific species, A. putjatini Zhukov, 1957, on morphological and biological grounds. Pellamyzon is transferred to the Plagioporinae. A new subfamily, the Opecoelininae subfam. nov., is erected for Opecoelina, which is considered to contain only two or three valid species, O. scorpaenae Manter, 1934, O. helicoleni Manter, 1934 (possibly a synonym of O. scorpaenae) and O. pacifica Manter, 1940. Both O. theragrae Lloyd, 1938, and O. radifistuli (Acena, 1941) are transferred to the genus Podocotyle Dujardin, 1845, as P. theragrae comb. nov. and P. radifistuli comb. nov. O. pharynmagna Annereaux, 1943, is judged to be a synonym of P. radifistuli, and both O. vixiintestina Oshmarin, 1965, and O. vixigastera Oshmarin, 1965, are considered unrecognizable. The possible evolutionary relationships of the subfamilies within the Opecoelidae are commented on.
