First data on the parasites of Hoplias aimara (Characiformes): description of two new species of gill monogeneans (Dactylogyridae)

Juliana Moreira, Tomáš Scholz and José Luis Luque
From the journal Acta Parasitologica


The first data on the parasites of the giant trahira, Hoplias aimara (Characiformes: Erythrinidae), a little known, but popular fish for sport angling, are provided. In H. aimara from the Xingu River in Brazil, two new species of gill monogeneans of the family Dactylogyridae were found and their description is provided herein. Urocleidoides aimarai n. sp. differs from all 18 congeners by the presence of a large accessory piece of the male copulatory organ and based by morphology of anchors. Urocleidoides xinguensis n. sp. is distinguished by unique combination of copulatory complex and haptoral structures.
