Urocleidus aculeatus (Van Cleave and Mueller, 1932) (Monogenea: Ancyrocephalinae) from Stizostedion vitreum (Mitchill) (Pisces: Percidae) in eastern North America: anatomy and systematic position

The Journal of Parasitology, 1981
Urocleidus adspectus Mueller, 1936 (Monogenea: Ancyrocephalinae), on the gills of yellow perch (Perca flavescens) in North America, is redescribed. Contrary to previous belief, the accessory piece articulates with the cirrus base and the vas deferens loops around the left intestinal crus.

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 ...

Population dynamics of Enterogyrus cichlidarum (Monogenea: Ancyrocephalinae) from the stomach of Tilapia spp. in Egypt

International Journal for Parasitology, 1990
In a 1-year seasonal study of the numbers of the stomach-inhabiting monogenean Enterogyrus cichlidarum in Tilapia nilotica in the River Nile, Egypt, prevalence and intensity reached a height in spring and infection levels were surprisingly high in winter. T. zillii harboured fewer parasites but seasonal changes were similar.

Additional Species of Ancyrocephalinae (Trematoda: Monogenea) from Darters of Southern Mississippi

American Midland Naturalist, 1970
Four new species of Ancyrocephalinae are described from darters (Percidae: Etheostomatinae) from Mississippi: Urocleidus ammocryptus from Ammocrypta beani Jordan, and Etheostoma parvipinne Gilbert and Swain; U. chlorosomus and U. lottensis from Etheostoma chlorosomum (Hay); and U. stigmaeus and U. chlorosomus from Etheostoma stigmaeum 'Jordan).

The evaluation for generic-level monophyly of Ancyrocephalinae (Monogenea, Dactylogyridae) using ribosomal DNA sequence data

Molecular Phylogenetics and Evolution, 2007
To overcome the limited regional and taxonomic coverage in previous studies of the Ancyrocephalinae (Monogenea, Dactylogyridae), we present further findings on the molecular systematics and phylogeny of a broader selection of specimens, aiming to build a molecular phylogeny of the Ancyrocephalinae, and to assess the monophyly of each available genus ...

DUPLACCESSORIUS ANDINUS N. GEN., N. SP. (DACTYLOGYRIDAE: ANCYROCEPHALINAE) FROM THE GILLS OF PERCICHTHYS TRUCHA (PERCIFORMES: PERCICHTHYIDAE) IN PATAGONIA, ARGENTINA

Journal of Parasitology, 2004
During a parasitological survey of Patagonian freshwater fishes, specimens of a new species of Monogenea were collected from the gills of Percichthys trucha (Perciformes: Percichthyidae). This species is described as the only member of a newly proposed genus of Ancyrocephalinae. Duplaccessorius n. gen.

Studies on Monogenetic Trematodes. XXV. Six New Species of Ancyrocephalinae from the Gills of Zanclus canescens (Linnaeus) with a Key to the Genera of Ancyrocephalinae

The Journal of Parasitology, 1964
Six new species of Ancyrocephalinae, namely, Hamatopeduncularia heraldi, Parahaliotrema dempsteri, P. parahaliotrema, Pseudohaliotrema brevis, P. canescens, and P. zanclus are described from the gills of the Moorish Idol, Zanclus canescens (Linnaeus). Parahaliotrema is proposed as a new genus.

PHYLOGENY OF SPECIES OF SCIADICLEITHRUM (MONOGENOIDEA: ANCYROCEPHALINAE), AND THEIR HISTORICAL BIOGEOGRAPHY IN THE NEOTROPICS

Journal of Parasitology, 2005
The phylogenetic relationships and historical biogeography of species of Sciadicleithrum parasitizing Neotropical cichlid fishes were studied. Hypotheses were: Did the presence of Sciadicleithrum species in southeast Mexico (SM) and Central America (CA) result from early dispersal of cichlid species from South America (SA) to the north via the Antilles

CICHLIDOGYRUS SCLEROSUS (MONOGENEA: ANCYROCEPHALINAE) AND ITS HOST, THE NILE TILAPIA (OREOCHROMIS NILOTICUS), AS BIOINDICATORS OF CHEMICAL POLLUTION

Journal of Parasitology, 2007
Experimental results showed that the gill monogenean Cichlidogyrus sclerosus and its host, the Nile tilapia Oreochromis niloticus, exhibited significant numerical and physiological responses after exposure to sediments polluted with polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls, and heavy metals in comparison with control fishes ...
