<em>Jainus piava</em> n. sp. is described from the gills of <em>Schizodon borellii</em> (Boulenger, 1900) (Characiform), commonly named as piava from the upper Paraná River floodplain, Brazil. The new species differs from the other members of <em>Jainus</em> in the following features: ventral bar thin broadly V-shaped and male copulatory organ (MCO) a coil of about 1.5 rings. <em>Jainus piava</em> n. sp. is similar to species of <em>Jainus</em> by having a ventral anchor base with flattened superficial root and elongate rodlike deep root.<br><em>Jainus piava</em> n. sp. is described from the gills of <em>Schizodon borellii</em> (Boulenger, 1900) (Characiform), commonly named as piava from the upper Paraná River floodplain, Brazil.
