| RESUMEN Se redescribe e ilustra a Saccocoelioides octavus <A HREF="#szidat70">Szidat 1970</A> y S. bacilliformis <A HREF="#szidat73">Szidat, 1973</A> (Digenea, Haploporidae) en base a material tipo depositado en la Colección Helmintológica del Museo Bernardino Rivadavia, Buenos Aires, Argentina. La descripción original de ambas especies es breve, imprecisa y los datos morfométricos de cada una están referidos a un solo espécimen. El estudio detallado de cinco especímenes tipo de S. octavus, colectados en los ciegos pilóricos de Astyanax fasciatus (Cuv.), del holotipo y siete paratipos de S. bacilliformis, colectados en los ciegos pilóricos de Astyanax bipunctatus, revela que ambas son morfológicamente y morfométricamente similares;... |

| Over a 7-year period, parasites have been collected from 28 species of groupers (Serranidae, Epinephelinae) in the waters off New Caledonia Host-parasite and parasite-host lists are provided, with a total of 337 host-parasite combinations, including 146 parasite identifications at the species level Results are included for isopods (5 species), copepods (19) monogeneans (56), digeneans (28), cestodes (12) and nematodes (12) When results are restricted to those 14 fish species for which more than five specimens were examined and to parasites identified at the species level, 109 host-parasite combinations were recorded, with 63 different species, of which monogeneans account for half (32 species), and an average of 4 5 parasite species per fish species... |

| The aim of this study was to evaluate the morphology of the species Sticholecitha serpentis Prudhoe, 1949 by means of histological procedures. Helminths were previously fixed in Railliet & Henry solution, uncompressed and were included in 2-hydroxyethyl-methacrylate. Longitudinal and transverse serial sections with a 4-mum thickness were performed in a microtome (Leica RM 2165), stained with haematoxylin-eosin and then analyzed in a computerized image analysis system (Qwin Lite 2.5, Leica). Structures of systematic value, such as oral sucker, acetabulum, prepharynx, pharynx, esophagus, intestinal caeca, vitelline glands, ovary, uterus, cirrus pouch and testicles were described. Structures that were poorly visible in total preparations were also... |

| ABSTRACT During a survey of helminth parasites of the brown ground snake, Atractus major Boulenger, 1894 (Serpentes: Dipsadidae) from Moyobamba, region of San Martin (northeastern Peru), a new species of Glossidiella Travassos, 1927 (Plagiorchiida: Plagiorchiidae) was found and is described herein based on morphological and ultrastructural data. The digeneans found in the lung were measured and drawings were made with a drawing tube. The ultrastructure was studied using scanning electron microscope. Glossidiella peruensis sp. nov. is easily distinguished from the type- and only species of the genus, Glossidiella ornata Travassos, 1927, by having an oblong cirrus sac (claviform in G. ornata), distinctly ovate testes (rounded testes in G. ornata) and... |

| Micropogonias furnieri (Desmarest, 1823) from the coast of Rio Grande do Sul State were examined and six trematodes species were recovered: Aponurus laguncula Looss, 1907, A. pyriformis (Linton, 1910), Monascus filiformis (Rudolphi, 1819), Opecoeloides catarinensis Amato, 1983, O. stenosomae Amato, 1983, and Pachycreadium gastrocotylum (Manter, 1940). All species are registered for the first time in Rio Grande do Sul State and M. furnieri represents a new host record for A. laguncula, A. pyriformis and M. filiformis. |

| ABSTRACT In the Amazon, the growing demand for fish has been boosting the expansion of fish farms. However, the intensification of cultivation can generate disequilibrium in the parasite-host environment, predisposing fish to parasitic infections. The objective of this study was to evaluate the community structure of metazoan parasites in cultivation systems of piauçu, Leporinus macrocephalus, in the state of Acre, Brazil. We examined 100 specimens from a semi-intensive cultivation system (earth tanks) and 100 from an extensive system (dams). Overall 66.5% of the hosts were parasitized. We collected 1,240 parasite specimens, classified in 15 metazoan taxa (10 monogenoidean, one digenean and four nematodes). The parasite prevalence was higher by... |

| ABSTRACT This study investigated the metazoan parasite fauna in Peckoltia braueri and Pterygoplichthys pardalis from a tributary of the Amazon River system, in northern Brazil. In P. braueri, 630 parasites were collected, belonging to Unilatus unilatus, Nothogyrodactylus sp., Genarchella genarchella, Proteocephalus sp., Gorytocephalus elongorchis, Dolops longicauda and Hirudinea gen. sp., with a dominance of monogenean species. In P. pardalis, 120 parasites were collected, belonging to U. unilatus, Acanthostomum gnerii and Gorytocephalus elongorchis, and this acanthocephalan was the dominant species. In both hosts, the parasites presented clumped distribution, high prevalence, low abundance, low Shannon diversity, and low species richness, with a... |

| ABSTRACT Austrodiplostomum compactum is a digenetic trematode whith metacercariae that occur in the eyes of a wide variety of fish species. In Brazil, A. compactum metacercariae have been reported in many fish species, but there are only a few studies in the Amazon region. Due to the lack of information in the Amazon, the aim of this study was to report the occurrence of A. compactum metacercariae in the eyes of 15 specimens of Plagioscion squamosissimus from the Lake Catalão, in Amazonas, Brazil. Fishes were collected using gill nets placed randomly in the lake, euthanized in a field laboratory, and had their eyes dissected and examined under a stereomicroscope. A total of 801 metacercariae were registered infecting the eyes of the hosts with a parasitic... |

| Descreve-se a histopatologia da parasitose de Loricariichthys platymetopon (Osteichthyes, Loricariidae) por Clinostomum marginatum (Digenea, Loricariidae). Os parasitas foram observados encistados na base das nadadeiras, músculo, face interna do opérculo, lábios, arcos branquiais, palato, placas ósseas e olhos, formando pequenos nódulos branco-amarelados. Em todos os locais, os parasitas estavam circundados por uma cápsula de tecido conjuntivo denso seguida, na maior parte dos casos, por uma outra de tecido conjuntivo frouxo. A espessura desta cápsula variou com a localização dos parasitas e, em alguns casos, observava-se a presença de linfócitos e macrófagos. Quando os parasitas encistavam junto do tegumento, verificava-se uma redução da altura do... |

| Uma nova espécie de Cladorchiidae (Trematoda, Digenea) foi encontrada no trato intestinal do peixe de água-doce “pacu peva”, Metynnis maculatus (Kner, 1858) na planície de inundação do Alto Rio Paraná, Brasil. A nova espécie foi classificada no gênero Dadayius Fukui, 1929 por apresentar testículos não lobados e acetábulo ventro-terminal com um “entalhe” postero-mediano na margem interior, características do gênero que possui apenas duas espécies conhecidas. Algumas características que diferem a espécie nova de D. marenzelleri (Daday, 1907) e D. pacuensis Thatcher, 1996 são cecos não alcançando o acetábulo, vitelária de extensão limitada e não atingindo o nível do testículo posterior e a presença de dois tamanhos diferentes de ovos em dois estágios de... |

| The specimens of surubim, Pseudoplatystoma corruscans (Spix and Agassiz, 1829), an important food fish with high commercial value in the Upper São Francisco River, were collected downstream from the Três Marias Dam, in the municipality of Três Marias, State of Minas Gerais, Brazil. Thirty-six individuals were examined and among the parasites, four species of Digenea were found: Witenbergia witenbergi Vaz, 1932 and Tylodelphys sp. (metacercarie), both with prevalence above 10%, followed by Acanthostomum gnerii (Szidat, 1958) and Acanthostomum sp.. The total length of the hosts did not influence the parasite prevalence. Witenbergia witenbergi occurred only in female hosts and the abundance of Tylodelphys sp. was higher in the males. These Digenea were... |
