The global fauna of Didymozoidae infecting fishes is very diverse and includes 270 species. Integrative taxonomic studies in this group are rare, genetic data lacking for the molecular identification In study, a new genus species, Platodidymocystis yamagutii n. gen., sp., described based on morphological analyses. allocated to Didymozoinae but differs from all other genera subfamily, mainly by morphology testes ovary. analysis phylogeny using 28S rDNA ITS2 markers showed P. sp. unique...
Three new species of Urocleidoides Mizelle & Price, 1964 are described from the gills characiform fishes in Tocantins River and its tributaries. boulengerellae sp. nov. is Boulengerella cuvieri (Spix Agassiz, 1829) differs all congeners by dorsal bar with a long posteromedial projection; male copulatory organ 2–3 counterclockwise rings base flange; an accessory piece comprising robust Y-shaped unit sheath-like unit; highly sclerotized vaginal canal. paratriangulus nov., Psectrogaster...
Several studies have demonstrated parasitism by monogenoids in characiform fish the Neotropics. During on helminth fauna of curimatids from Tocantins River, specimens Psectrogaster amazonica Eigenmann & Eigenmann, 1889 were examined and species Curvianchoratus Hanek, Molnar Fernando, 1974 found. Species genus are characterized mainly complex shape haptoral anchors with a modified dorsal anchor, composed two subunits, dorsal-median dorsal. To date, known to parasitize curimatid fishes:...
During a study conducted on the helminth fauna of fishes in middle Munim River basin, State Maranhão, northeastern Brazil, three species (two new) Diaphorocleidus Jogunoori, Kritsky & Venkatanarasaiah, 2004 are reported from gills “piaba” Bryconops cf. affinis (Iguanodectidae): (Mizelle, Crane, 1968), D. forcipiformis n. sp. and munimensis New morphological data, drawings, geographic distribution were provided for affinis. is characterized by male copulatory organ with 2½ rings...
Abstract The aim of this study was to describe a new species Didymozoidae (Trematoda) found in the mesentery Euthynnus alletteratus (Rafinesque) off Cabo Frio, coastal area state Rio de Janeiro, Brazil. Thirty specimens E. were obtained between August 2023 and June 2024, directly from traders who sell fresh fish markets. parasites fixed AFA (93% ethanol 70%, 5% formaldehyde 2% glacial acetic acid) with or without compression, stained Langeron’s hydrochloric carmine, dehydrated an alcohol...
ABSTRACT Oreochromis niloticus (Linnaeus) (Perciformes: Cichlidae), commonly named “tilapia”, is the second most cultivated species in world. Among diseases that affect tilapia are parasitic caused by parasites of class Monogenoidea. The aim present study was to analyze parasitism rates among specimens O. farming systems, after dietary supplementation with ractopamine, a growth promoter used for fattening fish. action this substance on quantitative parameters infestation Monogenoidea...
Five new species of Cosmetocleithrum were described parasitizing the gill filaments neotropical doradid fishes. undulatum n. sp., brachylecis sp. and ludovicense are from Platydoras a market-place São Luís, State Maranhão, Brazil. sacciforme basicomplexum Oxydoras niger Juruá River, Acre, resemble falsunilatum Feronato, Razzolini, Morey & Boeger, 2022 mainly by unique male copulatory organ (MCO) morphology but differ these all congeneric MCO, accessory piece hooks pairs. is closer to...
