Habitat. Limnogonus a. aduncus has usually been found in the margins of pools, ponds and lagoons exposed to sunlight and with floating, emergent or submerged vegetation (Melo & Nieser 2004; Pereira & Melo 2007; Molano-Rendón et al. 2008; Torres et al. 2008; Moreira et al. 2011a), as well as in stagnant waterbodies near lotic habitats (overflows of streams; pools on banks of rivers; pools along dry streams) (Roback 1966; Melo & Nieser 2004; Moreno-R et al. 2018). This subspecies has also been collected in streams and rivers which are slow to moderately fast-flowing, with or without aquatic vegetation and in shaded or unshaded areas (Mazzucconi & Bachmann 1995; Melo & Nieser 2004; Pereira & Melo 2007; Moreno-R et al. 2018; Rodrigues et al. 2021b).

At the INR, only two specimens were collected in a swimming pool in Concepción de Yaguareté Corá .

Remarks. The collection of L. aduncus aduncus from INR represents the first record from Corrientes Province.
