First record of Ophrydium versatile (Müller, 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 m 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.
