Buenoa fuscipennis: Kirkaldy, 1904: Wiener Ent. Zeit., 120, 134.

Material examined. Yahaveré RS: 2 ♂, 4 ♀, Trin Lagoon, 12.xii.2014.

General distribution. Venezuela, Brazil, Chile, Bolivia, Paraguay, Argentina, Uruguay (Barbosa & Nessimian 2013).

Habitat. Buenoa fuscipennis has been found in marshlands, temporary pools (including urban rain pools without aquatic vegetation), ponds, lakes, lagoons (exposed to sunlight and with dense floating vegetation), streams (exposed to sunshine, with submerged and emergent vegetation) and rivers (Bachmann 1962c; Corigliano et al. 1996; Fontanarrosa et al. 2004, 2013; Muzón et al. 2006). This species has also been found in swimming pools and taken at lights (Angrisano 1982; Torres et al. 2007; Dellapé & Carpintero 2012).

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 the Trin Lagoon from habitats similar to that mentioned above for the Iberá Lagoon.
