Belostoma dentatum: Montandon, 1903b : Bull. Soc. Sci. Bucarest, 116–117.

Material examined. Itatí RS: 2 ♂, 28–31.iii.2014. Laguna Iberá RS: 1 ♂, 1 ♀, Fernández Lagoon, 11.xii.2014. San Ignacio RS: 1 ♀, Reserva Privada Don Luis, Monte Don Luis, roadside ditches, 27°52.015’S, 56°54.914’W, 5.iii.2015.

General distribution. Brazil, Peru, Bolivia, Paraguay, Argentina, Uruguay ( Ribeiro et al. 2017).

Habitat. Belostoma dentatum has been found in ditches, ponds, lagoons (in vegetated margins), lakes, pools in dry side-stream, and in quiet edges of streams and rivers ( Nieser 1975; Melo & Nieser 2004; Ribeiro 2007; Armúa de Reyes & Kehr 2008; Ribeiro et al. 2017). This species has also been taken at lights ( Nieser 1975; Almeida et al. 2019).

At the INR, B. dentatum was collected from the margins of the Iberá Lagoon in shallow waters with emergent and floating vegetation (Estévez et al. 2003). During the present study, this species was collected at the margins of shaded ditches without aquatic vegetation, and from the margins of the Fernández Lagoon, exposed to sunlight and with emergent and floating vegetation.

Remarks. This species was previously recorded from INR by Estévez & Armúa de Reyes (2003).
