Telmatobates bonariensis Berg, 1898: Comun. Mus. Nac. B. Aires, 5–6.

Rheumatobates bonariensis: Drake & Harris, 1938: Notas Mus. La Plata, 201.

Material examined. On the road to Itatí RS: 1 ♀, Mercedes Department, Pay Ubre Chico Stream, Provincial Route 29, 28.iii.2014.

General distribution. Brazil, Peru, Bolivia, Paraguay, Argentina, Uruguay (Cordeiro & Moreira 2015).

Habitat. This species has been found in streams that are slow-flowing, with or without floating and emergent vegetation, with or without gallery forests, and in shaded or unshaded areas (Fernández & López Ruf 2006; Torres et al. 2007). It has also been collected in slow-flowing rivers, artificial reservoirs with marginal vegetation, shaded pools without aquatic vegetation, and shaded ponds with marginal vegetation caused by overflowing of streams (Mazzucconi & Bachmann 1995; Neri et al. 2005; Torres et al. 2007; Franco et al. 2021).

At the INR, specimens were collected in standing and slow-moving water along the margins with gallery forests and without aquatic vegetation of Pay Ubre Chico Stream, in shaded places.

Remarks. This is the first record of R. bonariensis from INR. This species was previously recorded from Corrientes Province by Bachmann (1966b), Mazzucconi & Bachmann (1995), Mazzucconi (1999) and Crespo & Iglesias (2001). Rheumatobates bonariensis was recorded from Córdoba by Corigliano et al. (1996) and Chaco, Formosa and Salta by Aristizábal-García (2002), based on Bachmann (1966b). These records are herein considered erroneous, because they are not mentioned in Bachmann (1966b). These erroneous records were repeated by Coscarón (2017).
