First Data on the Parasites of the Pacific Kingcroaker Menticirrhus elongatus (Perciformes: Sciaenidae): Description of a New Species of Rhamnocercoides (Dactylogyridea: Diplectanidae)

Acta Parasitologica, 2021
A new monogenean, Rhamnocercoides lambayequensis n. sp. (Dactylogyridea: Diplectanidae), is described based on the specimens collected from the gills of the Pacific kingcroaker Menticirrhus elongatus (Günther 1864) (Perciformes: Sciaenidae), a demersal fish endemic to Eastern Pacific, captured off the South American Pacific coast, Lambayeque Region ...

Muscular Arrangement and Sclerite Morphology in the Haptor of Tetraonchus monenteron (Monogenea, Dactylogyridea)

Acta Parasitologica, 2019
BACKGROUND : Tetraonchidae is a small and relatively monomorphic family of dactylogyroid monogeneans. Since the morphology of sclerites of the attachment organ (haptor) is one of the primary criteria in tetraonchid taxonomy, the confocal study of sclerites and associated musculature may provide valuable taxonomic information.

Phylogenetic Position of Sundanonchidae (Platyhelminthes: Monogenoidea: Dactylogyridea), with Report of Two Species of Sundanonchus from Toman, Channa micropeltes (Channiformes: Channidae), in Malaysia

Invertebrate Biology, 1995
Phylogenetic analysis of morphological characters provided a hypothesis for the origin of the Sundanonchidae within the Tetraonchinea (Dactylogyridea) as sister group to the Tetraonchidae. Sundanonchus tomanorum n. sp. is described and S. micropeltis is reported from the gills of toman, Channa micropeltes, from Tapah, Perak, Malaysia.

Phylogenetic relationships of the Dactylogyridae Bychowsky, 1933 (Monogenea: Dactylogyridea): the need for the systematic revision of the Ancyrocephalinae Bychowsky, 1937

Systematic Parasitology, 2003
Phylogenetic analyses based on partial 18S rDNA sequences of polyonchoinean monogeneans were conducted in order to investigate the relationships between selected families and subfamilies of the Dactylogyrinea, mainly within the Dactylogyridae. We tested the status of the Ancyrocephalidae sensu Bychowsky & Nagibina (1978) and the Ancyrocephalinae sensu ...

Evolution post-larvaire de l'appareil sensoriel chez les Dactylogyridea (Monogenea)

Zeitschrift Für Parasitenkunde (Berlin, Germany), 1979
L'evolution de la chetotaxie est suivie au cours du developpement post-larvaire chezDactylogyrus extensus Mueller et Van Cleave, 1932 (Dactylogyridae) et chezActinocleidus recurvatus Mizelle Donahue, 1944 (Ancyrocephalidae). Elle est caracterisee par la disparition rapide de sensilles dorsales des la fixation de l'oncomiracidium sur l'hote, puis par l ...

Morphological and molecular characterization of Chauhanellus peruvianus sp. nov. (Dactylogyridea, Dactylogyridae) from Galeichthys peruvianus (Siluriformes, Ariidae) in the Southern Pacific Ocean

Zootaxa
A new species of Chauhanellus Bychowsky & Nagibina, 1969 is described from the gills of the Peruvian sea catfish, Galeichthys peruvianus Lütken (Siluriformes, Ariidae), collected from the Southern Pacific Ocean off the coast of Peru. The description of the new species is based on an integrative taxonomic approach, incorporating morphological data ...

Insights into the phylogenetic position of genus Synodontella (Monopisthocotylea) among some other Dactylogyridea gill parasites of African catfishes and the importance of haptoral elements

African Journal of Aquatic Science
This work provides new molecular data on seven species representing three genera (Protoancylodiscoides, Schilbetrema and Synodontella)  in the order Dactylogyridea. The results help to explain the origin of Synodontella spp. and to elucidate the phylogenetic position of   Synodontella in relation to the other genera.

[Certain problems of the taxonomy of monogeneans of the order Dactylogyridea (Platyhelminthes: Monogenea)].

Parazitologiia, 2002
Different taxonomic problems of the Dactylogyridea Bychowsky, 1937 are discussed. From the recent point of view, all old genera need a careful revision. Taxa of higher ranks should be analysed taking into account their host phylogeny and zoogeography.

Two new Neotetraonchus species (Dactylogyridea, Dactylogyridae) parasitising the Peruvian sea catfish Galeichthys peruvianus (Siluriformes, Ariidae), including molecular data

Journal of Helminthology
Abstract As part of a parasitological survey, several specimens of two new monopisthocotylean species, Neotetraonchus celsomanueli sp. nov. and N.peruvianus sp. nov. (Dactylogyridea, Dactylogyridae), were collected from the gill filaments of the Peruvian sea catfish Galeichthys peruvianus (Siluriformes, Ariidae) off Puerto Pizarro, Tumbes region ...
