Notonectidae

Notonectidae is represented in Argentina by 24 species in three genera (Coscarón 2017). Poi de Neiff (1993) and Estévez et al. (2003) previously reported four species from INR. During this study, we collected these species and another three, including Buenoa unguis Truxal, 1953, which represents the first record of this species from Corrientes Province. Four species of Notonectidae ( Buenoa platycnemis (Fieber, 1851); Martarega guarani Mazzucconi, 2011; M. uruguayensis (Berg, 1883); Notonecta disturbata Hungerford, 1926), reported from Corrientes Province (Bachmann 1962 a, 1963, 1971; Nieser 1970a; López Ruf et al. 2003; Mazzucconi 2008, 2011; Torres et al. 2008), have not been collected from INR.
