Haptoral neuromusculature in two species of Dactylogyrus Diesing, 1850 (Monogenea: Dactylogyridae)
Systematic Parasitology, 2016The taxonomy of Dactylogyrus Diesing, 1850 (Monogenea: Dactylogyridae), like that of most monopisthocotyleans, relies heavily on the morphology of sclerites of the posterior attachment organ (haptor). However, the associated neuromusculature is essentially unknown and, therefore, the aim of this study was to use confocal microscopy to examine the ...

New Dactylogyridae (Trematoda: Monogenea) from Mississippi
American Midland Naturalist, 1962TwO new monogenetic trematodes Urocleidus nigrofasciatus n. sp. and Urocleidus macropterus n. sp. (Dactylogyridae: Tetraonchinae) are described and a third, Urocleidus wadei Seamster, 1948, is redescribed from freshwater fishes of Mississippi. The present paper is the first report of Tetraonchinae (Dactylogyridae) from freshwater fishes of southern ...

Studies on Monogenetic Trematodes XII. Dactylogyridae from Wisconsin Fishes
American Midland Naturalist, 1945The 17 species of Monogenea treated herein were collected from Wisconsin waters in 1947 by Dr. R. V. Bangham of Wooster College, Wooster, Ohio, to whom the authors express a debt of gratitude. The host material was first frozen and then preserved in formalin.

Experimental Parasitology, 2022
The development of dactylogyrids is dependent on water temperature, and their eggs fail to hatch below 5 °C. In the field, however, mean abundance of Dactylogyrus species increases and reaches a high level in winter, which suggests that infective oncomiracidia hatch from eggs in winter.

Comparative Parasitology, 2003
Abstract The results of a systematic survey of species of monogeneans (Dactylogyridae) collected from the gills of pimelodid, poeciliid, cichlid, and characid fishes from the Atlantic coast of Nicaragua in 1999 are presented. The following species were recovered: Ameloblastella chavarriai and Aphanoblastella travassosi occurred on the gills of Rhamdia ...

Studies on Monogenetic Trematodes. XVI. Rhamnocercinae, a New Subfamily of Dactylogyridae
American Midland Naturalist, 1954Examination of the gills of Umbrina roncador Jordan and Gilbert, collected in the Pacific Ocean off the pier of the Scripps Institution of Oceanography, revealed the presence of three species of monogenetic trematodes. One of these represents a new subfamily, new genus, and new species, to which the present paper is devoted. The authors are grateful to

Parasitology International, 2014
Within ectoparasitic fish monogeneans, the genus Ligophorus contains a high number of species from which several were recently described. The precise determination of their taxonomic status requires robust diagnostic morphologic features that rely predominantly on a restricted set of sclerotized structures.

Some Species of the Genus Tetrancistrum Goto and Kikuchi, 1917 (Monogenoidea: Dactylogyridae)
The Journal of Parasitology, 1967Species of Tetrancistrum from New Caledonian and Australian fishes are studied. Three new species are described. T. nasonis sp. n. from Naso annulatus differs from other species in the genus by the presence of an ejaculatory bulb, muscular projections in the wall of the copulation canal, and a copulatory organ consisting of a curved penis stylet with a
