Sigara fuscata Stål, 1859 : Kongl. Svensk. Freg. Eugenies Resa Omkring Jorden. IV. Zool., 268.

Tenagobia fuscata: Bergroth, 1899 : Ent. Mon. Mag., 2d Series, 282.

Material examined. Laguna Iberá RS: 2 ♀, Lobo Cuá Stream, 28°32’37.14’’S, 57°12’3.89’’W, 2.xii.2012; 1 ♂, 1 ♀, Lobo Cuá Stream, 28°32’52.66’’S, 57°12’38.56’’W, 2.xii.2012.

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

Habitat. Tenagobia fuscata has been found in the margins of ditches and lagoons exposed to sunlight and with floating, emergent, and submerged vegetation ( Ronderos et al. 1969; Nieser 1977; Bachmann 1979, 1981; Bachmann & Farina 1989). This species has also been collected in artificial channels, streams and rivers that are slow to moderately fast-flowing ( Bachmann 1962c, 1979, 1981; Bachmann & Farina 1989; Fernández & López Ruf 2006). It seems to prefer permanent shaded habitats (including small ones) with dense emergent and submerged vegetation and organic debris ( Bachmann 1981). This species has also been taken at lights ( Dellapé & Carpintero 2012).

At the INR, only a few specimens were collected from the vegetated margins of the Lobo Cuá Stream.

Remarks. The collection of T. fuscata from INR represents the first record from Corrientes Province.
