General distribution. Brazil, Argentina ( Cordeiro & Moreira 2015).

Habitat. This species has usually been found in streams without aquatic vegetation, in slow-moving water and in shaded areas ( Nieser & Melo 1997; Melo & Nieser 2004; Pelli et al. 2006; Torres et al. 2007), but it has also been collected in rivers and stagnant waterbodies connected to lotic ones (reservoirs and pools connected to streams; ponds at waterfall bases) in shaded areas ( Vianna & Melo 2003; Pelli et al. 2006), in a stream with aquatic vegetation ( Souza et al. 2006), and in a stream and overflow path in agricultural fields mostly exposed to sunlight ( Melo & Nieser 2004). This species has also been found in streams with gallery forests that run along their margins ( Pelli et al. 2006).

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

Remarks. The collection of B. furva from INR represents the first record from Corrientes Province.
