MANTER: Journal of Parasite Biodiversity

Steganoderma eamiqtrema n. sp. and a single unidentified specimen of Steganoderma Stafford, 1904 (Zoogonidae: Lepidophyllinae) obtained from the intestine of the greenstriped rockfish, Sebastes elongatus Ayres, 1859, and the flag rockfish, Sebastes rubrivinctus (Jordan and Gilbert, 1880) (Scorpaeniformes: Sebastidae), collected from 190–200 m depths off Oregon, USA, are described. The new species is distinguished from its seven other congeners by a diagnostic combination of morphological features including an elongate oval to spindle-shaped body, a clavate to comma-shaped cirrus pouch located in the forebody and hindbody, a bipartite seminal vesicle, a bifurcal or just post-bifurcal genital pore, a larger ventral than …


Gaharitrema Droneni N. Gen., N. Sp. (Digenea: Zoogonidae: Lepidophyllinae) From The Pudgy Cuskeel, Spectrunculus Grandis (Ophidiiformes: Ophidiidae), From Deep Waters Off Oregon, With Updates Keys To Zoogonid Subfamilies And Genera, Charles K. Blend, Gábor R. Rácz, Scott Gardner Mar 2020

Gaharitrema Droneni N. Gen., N. Sp. (Digenea: Zoogonidae: Lepidophyllinae) From The Pudgy Cuskeel, Spectrunculus Grandis (Ophidiiformes: Ophidiidae), From Deep Waters Off Oregon, With Updates Keys To Zoogonid Subfamilies And Genera, Charles K. Blend, Gábor R. Rácz, Scott Gardner

Scott L. Gardner Publications

Gaharitrema droneni n. gen., n. sp. (Digenea: Zoogonidae: Lepidophyllinae) is described from the intestine of the pudgy cuskeel, Spectrunculus grandis (Gu¨ nther, 1877) (Ophidiiformes: Ophidiidae), collected at 2,800 m depth from the northeastern Pacific Ocean off Oregon. The new genus is distinguished from Brachyenteron Manter, 1934 and Steganoderma Stafford, 1904, the 2 closest lepidophylline genera, and from 4 other zoogonid genera erected since 2007, the last major revision of the family, by a combination of diagnostic features including a pyriform or spindle-shaped body, smooth testes and ovary, narrow ceca that reach with the vitellarium into the hindbody, an unspecialized ventral …


Pseudopecoelus Mccauleyi N. Sp. And Podocotyle Sp. (Digenea: Opecoelidae) From The Deep Waters Off Oregon And British Columbia With An Updated Key To The Species Of Pseudopecoelus Von Wicklen, 1946 And Checklist Of Parasites From Lycodes Cortezianus (Perciformes: Zoarcidae), Charles K. Blend, Norman O. Dronen, Gábor R. Rácz, Scott Lyell Gardner Jan 2017

Scott L. Gardner Publications

Pseudopecoelus mccauleyi n. sp. (Opecoelidae: Opecoelinae) is described from the intestine of the bigfin eelpout, Lycodes cortezianus (Gilbert, 1890) (Perciformes: Zoarcidae), collected at 200–800 m depths in the northeastern Pacific Ocean off Oregon and Vancouver Island, British Columbia. The new species is distinguished by possessing a unique combination of the following diagnostic characters: vitelline fields that extend to the posterior margin of the ventral sucker; a slender, tubular and sinuous seminal vesicle that extends some distance into the hindbody; an unspecialized, protuberant ventral sucker; a genital pore at pharynx level; lobed to deeply multilobed testes; a lobed ovary; and an …


Lists Of Larval Worms From Marine Invertebrates Of The Pacific Coast Of North America, Hilda Lei Ching Jan 1991

Lists Of Larval Worms From Marine Invertebrates Of The Pacific Coast Of North America, Hilda Lei Ching

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Immature stages of seventy-three digenetic trematodes are listed by their families, marine invertebrate hosts, and localities and then cross listed according to their molluscan hosts. The list contains many new host records, and larval stages of fifteen digenetic trematodes were newly recorded from gastropods from British Columbia and California. A list of immature stages of fourteen cestodes, acanthocephaIans, and nematodes is also included.
