“…Fischthal and Allison (1941), Kohn (1990) and Bilong Bilong, Birgi, & Euzet (1994) recorded these parasites in urinary bladder. Kearn (1987), in a study about stingrays internal monogeneans, proposed that swimmers parasite larvae can have direct access to sewer and, from there, they can go for their sites of infection such as rectal glands.…”

ABSTRACT. Floodplains systems present complex biodiversity and upper Paraná river floodplain retains a wide variety of terrestrial and aquatic species. Serrasalmus marginatus (nonindigenous species) and Serrasalmus maculatus (native species) are part of this biodiversity component and can be infected by trophic transmission. In order to understand the ecological processes within the upper Paraná river floodplain, endoparasite fauna of those two hosts species were analyzed, considering prevalence, abundance, intensity and richness variables to determine this relationship. So, abundance of acantocephalan Echinorhynchus sp. was positively correlated to S. marginatus length, while Kritskyia annakohnae (Monogenea) prevalence and S. marginatus length presented a negative correlation. S. marginatus relative condition factor (Kn) was negatively and significantly associated to the abundance of K. annakohnae, and Kn of infected fish by that species is lower compared with the non-infected fish. Since hosts are in the context of the introducing of species, the research of endoparasites ecological variables allows to understansd infracommunity and component community as a way of analyzing the consequence of these parasites distribution in the native and non-native species.Keywords: neotropical floodplain, parasite ecology, invasive species, piranha.Fauna endoparasitária de Serrasalmus spp. (Characidae: Serrasalminae) de uma planície de inundação neotropical RESUMO. Sistemas de inundação possuem uma complexa biodiversidade. Por causa desta característica, a planície de inundação do alto rio Paraná abriga uma gama muito grande de espécies aquáticas e terrestres. Serrasalmus marginatus (espécie introduzida) e Serrasalmus maculatus (espécie nativa) compõem a ictiofauna desta área, e estes hospedeiros podem ser infectados por endoparasitos pela transmissão trófica. A fauna endoparasitária das duas espécies de peixes foi analisada por meio da prevalência, abundância, intensidade e riqueza para averiguar a relação destas com as variáveis dos hospedeiros. Observou-se que a abundância do acantocéfalo Echinorhynchus sp. está positivamente correlacionada com o comprimento de S. marginatus, enquanto existe uma correlação negativa e significativa entre a prevalência de Kritskyia annakohnae (Monogenea) e o comprimento de S. marginatus. O fator de condição relativo (Kn) de S. marginatus está relacionado negativa e significativamente com a abundância de K. annakohnae, e o Kn dos peixes parasitados por esta mesma espécie é mais baixo se comparado com os peixes não parasitados. Como os hospedeiros estão no contexto de introdução de espécies, as investigações das variáveis ecológicas dos endoparasitos possibilitam o conhecimento de cada infracomunidade e comunidade componente, como forma de delimitar a atuação dos parasitos na mediação da relação ecológica entre a espécie nativa e não nativa.Palavras-chave: planície de inundação neotropical, ecologia parasitária, espécie invasora, piranha.

ABSTRACT. This paper describes a new species of Kritskyia, K. eirasi n. sp., from the urinary bladder and ureters of Leporinus lacustris, "corró", an anostomid fish collected in the Upper Paraná River floodplain, Brazil. The new species was included in this genus because of the infection site, the absence of anchor, bar and 4A hooks and the sinistral vaginal aperture. It differs from the type species, K. moraveci and from the other known species of the genus, mainly by the shape of the copulatory complex. The accessory piece is distally complex, serving as a cirrus guide. The base of male copulatory organ, like in congeneric species, is adorned with a sclerotized fringe; however K. eirasi n. sp. presents an elongate projection of this fringe. It also differs from K. boegeri because of the lacking of sclerotized disk in vaginal aperture; and from K. annakohnae due to the absence of keel-like projection in the body's left margin.

A new species of Kritskyia Kohn, 1990 (Monogenea, Dactylogyridae, Ancyrocephalinae) is described from the urinary bladder of Salminus brasiliensis (Cuvier, 1816) (Characiformes, Characidae) from the Cuiabá River, the Pantanal wetlands, Brazil. The male copulatory apparatus of the new species differs from those of other species of the genus by the presence of a bipartite accessory piece (distally and proximally linked), one part grooved, serving as guide for distal portion of the MCO. Moreover, the vagina of the new species differs from those of congeners by possessing distal digitiform processes.
