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 …
Taxonomy And Systematics Of Plagioporus (Trematoda), With Descriptions Of 10 New Species From Freshwater Fishes Of The Nearctic, Thomas John Fayton
Taxonomy And Systematics Of Plagioporus (Trematoda), With Descriptions Of 10 New Species From Freshwater Fishes Of The Nearctic, Thomas John Fayton
Dissertations
The Opecoelidae Ozaki, 1925 is one of the largest families of digenetic trematodes of fishes. While the family is mostly marine/estuarine, invasion of freshwater hosts has occurred at least two times. The only representative freshwater plagioporine sequenced to date is Plagiocirrus loboides Curran, Overstreet, & Tkach, 2007, which previous phylogenetic analyses resolved as being related to deep water marine opecoelids. The taxonomy of the freshwater plagioporines, particularly Plagioporus, has long been confused; homoplasy is rife within the family and has complicated the delineation of species and genera, and the freshwater species from marine forms. Here, I hypothesize that the …

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
The generic diagnosis of Nagmia Nagaty, 1930, is emended to include species having some vitelline follicles extending into the extracecal space. Two new species belonging in the genus are described from the Gulf of California: Nagmia rodmani n. sp. from the body cavity of the giant electric ray, Narcine entemedor Jordan and Starks, 1895, and Nagmia cisloi n. sp. from the body cavity of the smoothtail mobula, Mobula thurstoni (Lloyd, 1908). Both species are distinguished from each other and the 13 other known congeners by the number of testicular follicles, ratio of widths of oral sucker to ventral sucker, and …

Redescription Of Cryptocotyle Thapari Mcintosh, 1953 (Trematoda: Heterophyidae), In The River Otter Lutra Longicaudis From Bolivia, Scott Lyell Gardner, Peter T. Thew
Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
Cryptocotyle thapari McIntosh, 1953 (Digenea: Heterophyidae), collected originally from a South American otter that died at the U.S. National Zoo in Washington, D.C., is redescribed from specimens obtained from a river otter, Lutra longicaudis, collected from the Rı´o Matos in the Departamento de Beni, Bolivia. These individuals of C. thapari are slightly smaller than the type specimens, but they have similar features, including testes arranged in tandem and a well-defined ventrogenital sac. We redescribe this species because the original description was based on only 3 individuals, and the figures lacked detail. This is the first record of Cryptocotyle from …
Psettarium Anthicum Sp. N. (Digenea: Sanguinicolidae) From The Heart Of Cobia Rachycentron Canadum (Rachycentridae) In The Northern Gulf Of Mexico, Stephen A. Bullard, Robin M. Overstreet
Psettarium Anthicum Sp. N. (Digenea: Sanguinicolidae) From The Heart Of Cobia Rachycentron Canadum (Rachycentridae) In The Northern Gulf Of Mexico, Stephen A. Bullard, Robin M. Overstreet
