General distribution. The Lesser Antilles, Guyana, Suriname, Brazil, Peru, Bolivia, Paraguay, Argentina ( Barbosa & Nessimian 2013).

Habitat. Buenoa amnigenus has been found in the margins of ditches, drains, mangrove swamps, pools, ponds, and natural and artificial lakes, mostly exposed to sunlight and with floating, emergent, submerged vegetation and rivers ( Truxal 1953; Nieser 1975; Nieser & Alkins-Koo 1991; Barbosa & Nessimian 2013). It has also been taken at lights ( Nieser 1975; Barbosa & Nessimian 2013).

At the INR, specimens were 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 in flood-prone areas (together with B. salutis ) and streams with unshaded margins and with dense emergent vegetation. Additional specimens of this species were taken at lights in San Ignacio Ranger Station and Laguna Iberá Ranger Station.
