Abstract

Two new species of Sciadicleithrum are described from the gills of Neotropical cichlid fishes collected from Paraná River, Brazil. Sciadicleithrum satanopercae sp. nov. is described from the gills of Satanoperca pappaterra and differs from congeners by having a dorsal anchor with the distal portion complex and the inner margin with a “denticulum” between shaft and point. Sciadicleithrum joanae sp. nov. is described from the gills of Crenicichla niederleinii and C. britskii collected from Paraná River. Sciadicleithrum joanae sp. nov. differs from congeners by having a male copulatory organ comprising about half a clockwise loop and a vaginal pore “bulb-shaped”.
