MONOGENEA COMMUNITY ON THE GILLS OF Pimelodus albicans (VALENCIENNES, 1840) IN THE NORTHERN SALADO RIVER, SAN JUSTO (SANTA FE, ARGENTINA). Parasitol. latinoam.

It was studied the monogenean communities on the gills of a Pimelodus albicans Valenciennes, 1840 juvenile, in the Northern Salado River, tributary of the Middle Paraná River (Argentina). Monogenea taxa were found: Demidospermus armostus, Demidospermus bidiverticulatum, Demidospermus idolus, Demidospermus majusculus, Scleroductus yuncensi, Demidospermus sp and Ancyrocephalinae sp. The results allow us to conclude that: D. majusculus, D. armostus, D. idolus and Ancyrocephalinae sp were secondary species and there is no a dominant one. The local diversity of parasites is moderate and there is no correlation between the size of the hosts and the intensity of parasitism. In this article, the infrapopulations and infracommunities of monogenean of P. albicans, were analyzed. These reports show a new geographical distribution register ofneotropical monogenean species.
