Abstract
Jainus piava n. sp. is described from the gills of Schizodon borellii (Boulenger, 1900) (Characiform), commonly named as piava from the upper Parana River floodplain, Brazil. The new species differs from the other members of Jainus in the following features: ventral bar thin broadly V-shaped and male copulatory organ (MCO) a coil of about 1.5 rings. Jainus piava n. sp. is similar to species of Jainus by having a ventral anchor base with flattened superficial root and elongate rodlike deep root.
Highlights
According to Pavanelli et al (2004), in Brazil there have been few studies about the ecology of freshwater fish parasites
The upper Paraná River floodplain has 153 fish species; of these, around 12 species belong to the family Anostomidae (AGOSTINHO et al, 2004)
Eleven specimens of S. borellii were collected from September 2006 to September 2007 with nets in the upper Paraná river floodplain (22o50’ – 22o70’S and 53o15’ – 53o40’W), southern Brazil
Summary
According to Pavanelli et al (2004), in Brazil there have been few studies about the ecology of freshwater fish parasites. This occurs due to a scarcity of systematic works on fish parasites. The following species of monogeneans were described parasitizing Anostomidae from South America: Tereancistrum parvus Kritsky, Thatcher & Kayton, 1980 from Leporinus fasciatus (Bloch, 1794); Rhinoxenus arietinus (Kritsky, Boeger & Thatcher, 1988) from Rhytiodus argenteofuscus (Kner, 1858); Urocleidoides paradoxus (Kritsky, Thatcher & Boeger 1986) from R. microlepis (Kner, 1858); Rhinoxenus arietinus (Kritsky, Boeger & Thatcher, 1988), R. nyttus Kritsky, Boeger &Thatcher, 1988 from Schizodon fasciatus (Spix & Agassiz, 1829) and Jainus sp.
