Previous issue date: 2009-02-19 / Conselho Nacional de Desenvolvimento Cient?fico e Tecnol?gico / Between the period from August 2005 to August 2007 were collected and analyzed 565 specimens belonging to 20 species from the Guandu River, near the dam of water treatment station (WTS) (22 ? 48 ' 32 "S, 43 ? 37'35" W), State of Rio de Janeiro, to study the biodiversity of the monogeneans from Guandu river, considering the strategic importance of this river in the State of Rio de Janeiro. Of the 20 fish species studied in this work, 13 were parasitized by monogeneans. All monogeneans were found parasitizing the gills of the hosts. A total of 24 species of monogenean were found, with 18 belonging to the family Dactylogyridae Bychowsky, 1933, four belonging to the family Gyrodactylidae Van Beneden and Hesse, 1863 and two belonging to the family Diplectanidae Monticelli, 1903. Fish belonging to the families Auchenipteridae, Cichlidae, Heptapteridae, Mugilidae and Pimelodidae were parasitized by only monogenean family Dactylogyridae. The family Centropomidae was parasitized by only monogenean belonging to the family Diplectanidae. The fishes of the families Anostomidae, Characidae and Loricariidae were parasitized by monogeneans belonging to the families Dactylogyridae and Gyrodactylidae. In this work are described six new species of monogeneans, being one species of Jainus, four species of Ligophorus and one species of Rhabdosynochus, respectively parasitizing Leporinus copelandii Steindachner, 1875, Mugil liza Valenciennes, 1836 and Centropomus undecimalis (Bloch, 1792). In this study were made 12 new records of hosts and 21 new records of locality.

Das 20 esp?cies de peixes estudadas no presente trabalho, 13 estavam parasitadas por monogen?ticos. Todos os monogen?ticos encontrados estavam parasitando as br?nquias dos hospedeiros. Um total de 24 esp?cies de monogen?ticos foram encontradas, sendo 18 pertencentes ? fam?lia Dactylogyridae Bychowsky, 1933, quatro pertencentes ? fam?lia Gyrodactylidae Van Beneden e Hesse, 1863 e duas pertencentes ? fam?lia Diplectanidae Monticelli, 1903. Os peixes pertencentes ?s fam?lias Auchenipteridae, Cichlidae, Heptapteridae, Mugilidae e Pimelodidae foram parasitados exclusivamente por monogen?ticos da fam?lia Dactylogyridae. As esp?cies da fam?lia Centropomidae foram parasitadas somente por monogen?ticos pertencentes ? fam?lia Diplectanidae. As esp?cies estudadas das fam?lias Anostomidae, Characidae e Loricariidae foram parasitadas pelos monogen?ticos das fam?lias Dactylogyridae e Gyrodactylidae. No presente trabalho est?o sendo descritas seis esp?cies novas de monogen?ticos, sendo uma esp?cie de Jainus, quatro esp?cies de Ligophorus e uma esp?cie de Rhabdosynochus, parasitando respectivamente Leporinus copelandii Steindachner, 1875, Mugil liza Valenciennes, 1836 e Centropomus undecimalis (Bloch, 1792). No presente trabalho foram realizados 12 novos registros de hospedeiros e 21 novos registros de localidade.
