“…These characters are commonly used in taxonomy and phylogeny of the genus Apareiodon by Pavanelli (2006). We also included an additional measure, following Pavanelli and Britski (2003): the distance between the isthmus origin and pectoral-fin origin. Table 1.…”

“…Species of this genus shows trophic and habitat plasticity and are found dwelling in streams, rivers, and reservoirs (Bialetzki et al 1998). This genus has been recorded in the Paraná, São Francisco, and Tocantins river basins and in small coastal rivers from northeast Brazil (Sazima 1980, Bialetzki et al 1998, Pavanelli and Britski 2003.…”

“…The genus Apareiodon has 18 valid species is defined by a spatulate and edentulous lower jaw (Pavanelli 2003, Pavanelli andBritski 2003). They are small individuals of low economic value and have already been used as forage for larger fish species and as bait for sport fishing (Bialetzki et al 1998).…”

The first records of 2 species of Parodontidae (Apareiodon piracicabae and A. itapicuruensis) are reported in the Paraíba do Sul river basin. In total, 101 individuals of A. piracicabae and 3 individuals of A. itapicuruensis were collected in the Paraíba do Sul middle reaches. A description and diagnosis of both species based on morpho-meristic characters were provided. These fishes have been used as forage for larger fish species as well as bait for sport fishing, which may have facilitated their introduction in the Paraíba do Sul River from fish culture farms in the region. Key wordsApareiodon; geographic distribution; occurrence; Paraíba do Sul River.

We review species of Parodon Valenciennes, 1850 from the Magdalena, Cauca, Orinoco, Amazonas, Atrato and CaribbeanGuajira River basins of Colombia using meristic and morphological characters. We recognize eight valid species, five previously described: P. apolinari Myers, from the Orinoco River basin; P. buckleyi Boulenger and P. pongoensis (Allen) from the upper Amazon; P. caliensis Boulenger, from the upper Cauca River drainage; and P. suborbitalis Valenciennes, from Lake Maracaibo basin. Three new species are described: P. alfonsoi, from the lower Magdalena River drainage; P. magdalenensis, from the middle Magdalena and upper Cauca River drainages; and P. atratoensis, from the Atrato River basin. We redescribe Parodon suborbitalis using type specimens and topotypes, and designate lectotypes. A taxonomic key is included for identification of the species, as well as geographic distribution maps.Espécies de Parodon Valenciennes, 1850 provenientes das bacias dos rios Magdalena, Cauca, Orinoco, Amazonas, Atrato e Caribe-Guajira da Colômbia são revisadas com base em caracteres merísticos e morfológicos. Oito espécies são consideradas válidas, sendo cinco previamente descritas: P. apolinari Myers, da bacia do rio Orinoco, P. buckleyi Boulenger e P. pongoensis (Allen) do alto rio Amazonas, P. caliensis Boulenger do alto rio Cauca e P. suborbitalis Valenciennes da bacia do lago Maracaibo. Três novas espécies são descritas: P. alfonsoi, do baixo rio Magdalena; P. magdalenensis, do médio rio Magdalena e da bacia superior do rio Cauca e P. atratoensis, da bacia do rio Atrato. Parodon suborbitalis é redescrita a partir de espécimes-tipo e topótipos. Designam-se lectótipos de P. suborbitalis. Uma chave para identificação das espécies é incluída, bem como mapas de distribuição geográfica.

“…The species belongs to a genus widely distributed in South America, except in the South Atlantic, Patagonia and main channel of the Amazon River basins (Pavanelli & Britski, 2003). Parodontids have very different reproductive periods that do not overlap (Barbieri et al, 1983).…”

Cost of territorial maintenance by Parodon nasus (Osteichthyes: Parodontidae) in a Neotropical stream

et al. 2009

The combined demand over a certain resource may exceed its immediate supply, which can then lead to competition between individuals. This competition may result in territorial behavior. In this study we determine the density and spatial distribution, describe the interactions arising from territorial behavior and evaluate the costs of keeping the territories defended by adults of Parodon nasus. The study was conducted in Camarinha Stream located in the Serra das Araras Ecological Station, Porto Estrela, State of Mato Grosso, Brazil. The density was constant throughout the length of the stream, with a mean (± standard deviation) of 1.01 ind./m 2 (± 0.14). Our results show that the spatial distribution of individuals in the area ranged between uniform and random. The territories were defended more often against intraspecific than interspecific intruders. The time that the owners of the territories devoted to defending them was not influenced by the size of the territories. However, owners of larger territories spent more time foraging than owners of smaller territories. As a result, owners of larger territories had less time to rest than owners of smaller territories. The results of this study show behavioral patterns relevant to understanding the relationship between size and territorial maintenance cost of P. nasus and other species of fish with territorial behavior.A demanda combinada por um recurso pode exceder a sua oferta imediata, levando os indivíduos a competirem. Essa competição pode resultar no comportamento de territorialidade. Neste trabalho nós determinamos a densidade e a distribuição espacial, descrevemos as interações decorrentes do comportamento territorial e avaliamos os custos de manutenção dos territórios defendidos por indivíduos adultos de Parodon nasus. O estudo foi realizado no córrego Camarinha localizado na Estação Ecológica Serra das Araras no município de Porto Estrela, Mato Grosso, Brasil. A densidade foi constante ao longo de todos os trechos, com média (± desvio padrão) de 1,01 ind./m 2 (± 0,14). Nossos resultados mostram que a distribuição espacial dos indivíduos na área variou entre uniforme e aleatória. Os territórios foram defendidos mais frequentemente contra invasores intra do que interespecíficos. O tempo que os detentores de território dedicaram a sua defesa não foi influenciado pelo tamanho dos territórios. Todavia, donos de territórios maiores passaram mais tempo em atividade de forrageamento que donos de territórios menores. Como consequência, donos de territórios maiores tiveram menos tempo para descansar que donos de territórios menores. Os resultados deste trabalho mostram padrões comportamentais importantes para o entendimento da relação entre tamanho e custo de manutenção dos territórios de P. nasus e de outras espécies de peixes com comportamento territorial.
