Abstract: Hoplerythrinus unitaeniatus is popularly known as jeju or aimara. Widely distributed, occurs in many Central and South America basins, with the São Francisco River as type locality. In Brazil, the southernmost record of the species is the Uruguay River, Rio Grande do Sul State. This study reports the first record of H. unitaeniatus in the Patos Lagoon system, Guaiba hydrographic region, state of Rio Grande do Sul, Brazil. The capture occurred in a floodplain adjacent of the Sinos River near São Leopoldo city (… Show more

“…This result may indicate that, in this environment, H. unitaeniatus finds favorable conditions for its survival. Similar results were reported by Polez et al (2003) and Leal et al (2010), who verified the establishment of the species in places with high temperatures and that this species presents morphological adaptations that guarantee the capacity to survive long periods of hypoxia. Teodosio (2012) observed that this is the most visibly modified point and that it presented the highest percentage of exotic species.…”

“…On the other hand, H. unitaeniatus has been parasitized by species of crustaceans (MALTA, 1984;LEAL et al, 2010), nematodes (MARTINS et al, 2005;BENIGNO et al, 2012) and acanthocephalans ). However, the structure of the parasite communities and infracommunities of these two hosts has not been studied.…”
