| A new species of Demidospermus Suriano, 1983 is described from the gills of Auchenipterus osteomystax Miranda-Ribeiro, 1918 (Auchenipteridae), collected in the upper Paraná river floodplain, Brazil. The gills were removed and preserved in 5% formalin. Later the parasites were removed from the gills with the aid of a stereomicroscope and conserved in 70% alcohol. Some specimens were stained with Gomori’s trichrome, dehydrated in absolute alcohol and cleared with faia creosote to observe the internal organs. Other specimens were mounted in Hoyer’s medium for the study of the sclerotized structures. The present study describes a new monogenetic species, Demidospermus osteomystax n. sp., characterized by: tandem gonads; V-shaped haptoral bars with... |

| Surumanha, Auchenipterus osteomystax Miranda-Ribeiro, 1918 is an insectivorous species that inhabits benthopelagic freshwater environments. In order to know the parasitic fauna and aspects of the host-parasite relationship in surumanhas from Rosana’s hydroelectric reservoir and the upper Paraná river floodplain, 36 specimens from the reservoir and 41 specimens from the floodplain were collected, using gill nets. The parasitic fauna of the hosts from the different environments presented low similarity; among ten parasite species present in A. osteomystax, only two were observed in both environments. It was observed significant difference in the prevalence of the metacercariae of Strigeidae in relation to the sex of the hosts from the floodplain, indicating... |
