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

Habitat. Sigara chrostowskii has been found in pools (including urban rain pools without aquatic vegetation), lagoons (with dense vegetation), streams and rivers ( Hungerford 1948; Bachmann 1962c; Fontanarrosa et al. 2004, 2013; Fernández & López Ruf 2006). It has also been taken at lights ( Bachmann 1981). This species seems to prefer small lentic habitats with dense vegetation and organic debris, and slow-flowing streams ( Bachmann 1981).

Sigara chrostowskii was previously recorded from Iberá in association with Leersia hexandra and Cabomba caroliniana ( Poi de Neiff 1993, 2003). During the present study, it was collected from margins with dense floating, emergent and submerged vegetation (mainly Azolla filiculoides , Pontederia azurea , P. crassipes , P. cordata , Hydrocleys nymphoides , Nymphoides indica and Salvinia biloba ) in ponds (including artificial ones), marshlands, floodprone areas, and Iberá Lagoon. Additional specimens of this species were taken at lights in San Ignacio Ranger Station, San Nicolás Ranger Station and Laguna Iberá Ranger Station.

Remarks. Sigara chrostowskii was very often collected together with S. platensis .
