Some Diclidophorid Monogenea (Trematoda), including Two New Species, from Marine Fishes of the Eastern Pacific Ocean off California, U.S.A. and Baja California, Mexico

Cyclocotyloides bergstadi n. sp. (Monogenoidea: Diclidophoridae: Diclidophoropsinae) from the Gills of Grenadier, Coryphaenoides brevibarbis (Teleostei: Macrouridae), in the Northeast Atlantic Ocean

“…McCauley and Smoker (1969) also recognized Cyclocotyloides but proposed the monotypic Cyclocotyloidinae McCauley and Smoker, 1969 within the Diclidophoridae for the genus. Subsequent revisions by Mamaev and Lyadov (1975) and Mamaev (1976) place the genus in the Diclidophoropsinae of the Diclidophoridae, with Payne (1987) adopting these latter assignments. Campbell et al (1980), who reported Cyclocotyloides sp.…”

“…In a revision of the Diclidophoridae, Price (1943) transferred D. pinguis to Cyclocotyloides Price, 1943 as Cyclocotyloides pinguis (Linton, 1940) Price, 1943 based on the absence of clamp-like haptoral suckers, presence of a muscular genital atrium, and absence of an armed cirrus in the type specimens of the species. Although C. pinguis has been subsequently reported from A. pectoralis and other macrourid fishes (Mamaev and Lyadov, 1975;Payne, 1987;Zubchenko, 1975Zubchenko, , 1981McCauley and Smoker, 1969), Cyclocotyloides has remained monotypic. During investigations of the parasites of deep-sea fishes of the North Atlantic Ocean, a species of Cyclocotyloides was recovered from the gills of the deepsea macrourid, Coryphaenoides brevibarbis (Goode and Bean).…”

A new monogenean species parasitic on gills of bigmouth sole, Hippoglossina stomata Steindachner, 1876 from Southern California

“…Mamaev 1987;Ogawa 1999) and also family Synodontidae ( cf. Payne 1987). The type species is N. affine (Linton, 1898) Price, 1943, found on the palate of Paralichthys dentatus (family Paralichthyidae) from the Atlantic and P. lethosto mus (lethostigmus?)…”

“…( family Paralichthyidae) in the Gulf of Mexico. Fourth species, N. mcdonaldi Payne, 1987, was recovered from the gills of Synodus lucioceps (Ayres) (family Synodontidae) collected in the Gulf of California. The fifth spcies is N insularis Oliva et Luque, 1995, was found on the gills of Paralichthys sp.…”
