First record of Ophrydium versatile (Muller, 1786) Ehrenberg, 1838 (Protista: Peritrichida: Ophrydiidae) from the High Paraná River influence area (Misiones, Province, Argentina).

Abstract

Ophrydium versatile, a green protozoon that form sessile colonies is reported for the first time for the Misiones Province, Argentina from shallow waters of a recently formed pond in the Garupá Stream floodplain, at about 900 meters away from the confluence with the High Paraná River. To our knowledge this constitutes the second and northernmost record of the species for Argentina and the first for a subtropical environment in the country.
