Material examined. San Ignacio RS: 1 ♂, light trap, 27°49’26.52’’S, 56°50’52.26’’W, 16.xi.2018. Yahaveré RS: 4 ♂, 1 ♀, Trin Lagoon, 12.xii.2014.

General distribution. Brazil, Bolivia, Paraguay, Argentina ( Moreira et al. 2011b).

Habitat. Sigara denseconscripta has been found in lagoons, marshlands, streams and rivers ( Poi de Neiff 1990; Corigliano et al. 1996; Fontanarrosa et al. 2004, 2013; Muzón et al. 2006). It has also been taken at lights ( Bernardo et al. 2012). This species seems to prefer small and temporary lentic habitats, with scarce or no vegetation, and turbid waters warmed by the sun ( Bachmann 1981).

At the INR, specimens were collected from the margins of the Trin Lagoon, in shallow waters with submerged, emergent, and floating vegetation. One specimen of this species was taken at a light in San Ignacio Ranger Station.

Remarks. This is the first record of S. denseconscripta from the INR. This species was previously recorded from Corrientes Province by Contartese & Bachmann (1986) and López Ruf et al. (2003).
