Effects of different regimes of low temperature on egg hatching of Dactylogyrus vastator (Monogenea: Dactylogyridae)

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.

Studies on Monogenetic Trematodes XII. Dactylogyridae from Wisconsin Fishes

American Midland Naturalist, 1945
The 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.

Monogeneans (Dactylogyridae: Ancyrocephalinae) of Freshwater Fishes from the Caribbean Coast of Nicaragua

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, 1954
Examination 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

Some Species of the Genus Tetrancistrum Goto and Kikuchi, 1917 (Monogenoidea: Dactylogyridae)

The Journal of Parasitology, 1967
Species 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

Phylogeny of the Atlantic and Pacific species of Ligophorus (Monogenea: Dactylogyridae): Morphology vs. molecules

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.

Ultrastructure of the protonephridial system of Dactylogyrus sp. and an unidentified ancyrocephaline (Monogenea: Dactylogyridae)

International Journal for Parasitology, 1989
The ultrastructure of the flame bulbs and capillaries of the protonephridia of Dactylogyrus (probably anchoratus) from Carassius auratus in southeastern Australia, and of an unidentified ancyrocephaline from the marine teleost Priacanthus macracanthus in southern Queensland is described. The cilia of the flame are anchored in the terminal cell by means
