On some trematodes parasites of fishes from Paraná River

Abstract

Crassicutis cichlasomae Manter, 1936 is redescribed for the first time in South America and from a new host: Geophagus brasiliensis (Cichlidae). Iheringtrema iheringi Travassos, 1948 is redescribed for the first time since its original description from Pseudopimelodus zungaro (Pimelodidae); and new host records are referred to Genarchella genarchella Travassos et al., 1928, and to Parspina argentinensis (Szidat, 1954). Other reported species are: Microrchis oligovitellum Lunaschi, 1987, Neocladocystis intestinalis (Vaz, 1932), Pseudosellacotyla lutzi (Freitas, 1941), Thometrema overstreeti (Brooks et al., 1979) and Zonocotyle bicaecata Travassos, 1948. Original figures and measurements are presented.

Endohelminths in Cichla piquiti(Perciformes, Cichlidae) from the Paraná River, São Paulo State, Brazil

“…Cichla piquiti was identified as a new host for A. compactum metacercariae, G. genarchella, P. (Procamallanus) peraccuratus and third-stage larvae of anisakid nematodes of the genus Hysterothylacium. All identified parasites have been previously found in the Paraná River Basin (MORAVEC et al, 1993;KOHN, 2001;TAKEMOTO et al, 2009;KOHN et al, 2011;LACERDA et al, 2013), but this is the first report of these parasite species in the study area.…”

“…in the Paraná River, municipality of Pirassununga, São Paulo State, Brazil. Trematodes of this genus parasitise the anterior portion of the digestive tract (oesophagus, stomach and oral cavity) of freshwater fish, and G. genarchella is widely distributed in characid fish in Brazil, Argentina and Uruguay (TRAVASSOS et al, 1969;KOHN et al, 1990) but also occurs in the fish of the Pimelodidae family (HAMANN, 1989;KOHN, 2001). This is the first report of G. genarchella in a host of the family Cichlidae, increasing the list of hosts for this parasite and confirming its low specificity.…”

Are similar the parasite communities structure ofTrachelyopterus coriaceus and Trachelyopterus galeatus (Siluriformes: Auchenipteridae) in the Amazon basin?

“…In wild populations of T. galeatus of the Brazil, only the following helminths such 2 species of digeneans, 3 nematodes and 1 cestode are known (PAVANELLI & SANTOS, 1990;FERNANDES & KOHN, 2001;DIAS et al, 2006;TAKEMOTO & LIZAMA, 2009;KOHN et al, 2011). In wild populations of T. galeatus of the Argentina, there have been reports only 2 species digeneans (LUNASCHI, 1989;LUNASCHI & SUTTON, 1995).…”

Helminth fauna parasitizing Pimelodus pohli (Actinopterygii: Pimelodidae) from the upper São Francisco River, Brazil

“…Studies on parasitism in pimelodids have been also conducted in other localities of Brazil, such as some helminth parasites of species of Pimelodus Lacepède, 1803: P. blochii Valenciennes, 1840in Paraná River (KOHN et al, 1997; P. fur (Lütken, 1874) in Paraná River ; P. maculatus in Amazon Basin in Guaiba River (KOHN;FRÓES, 1986;FORTES et al, 1993;SARMENTO et al, 1995); in Guandu River (SANTOS et al, 2007;ALBUQUERQUE et al, 2008;AZEVEDO et al, 2010); in Itajaí-Açu River (BACHMANN et al, 2007); in Mogi Guaçu River (TRAVASSOS; KOHN, 1965;KOHN et al, 1985;FERNANDES, 1987;AGUIAR et al, 2011); in Paraiba do Sul River (VENANCIO et al, 2010); in Paraná River (TRAVASSOS; KOHN, 1965;MACHADO DOS SANTOS, 1992;MORAVEC et al, 1993MORAVEC et al, , 1997KOHN et al, 1997;PAVANELLI, 2004;KOHN, 2008;KOHN et al, 2011;LOPES et al, 2011); in Paranapanema River (RAMOS et al, 2013); Pimelodus microstoma Steindachner, 1877 in Mogi Guaçu River (AGUIAR et al, 2011) [note of the authors: this fish species was cited by the authors as P. heraldoi Azpelicueta, 2001, that is a junior synonym of P. microstoma Stein., sensu Ribeiro and Lucena (2010) KOHN, 2001;KOHN et al, 2011); Pimelodus sp. in Amazon Basin (VICENTE et al, 1978).…”
