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

Habitat. Pelocoris procurrens has been found in rivers, streams and ponds (Montandon 1895; Nieser 1975; López Ruf 1989, 1994b).

During the present study, P. procurrens was collected from unshaded margins with dense floating, emergent and submerged vegetation (mainly Azolla filiculoides, Pontederia azurea, P. crassipes, P. cordata, Myriophyllum aquaticum, Nymphoides indica, Egeria densa, Sagittaria montevidensis, Cyperus giganteus, Hydrocleys nymphoides and Salvinia biloba) in lentic habitats (Luna Lagoon, Galarza Lagoon, Iberá Lagoon, marshes, marshlands, ditches, ponds and flood-prone areas), and lotic habitats (Yacaré Stream, Corriente Stream, Isirí Stream, Carambola Stream, Lobo Cuá Stream, Pay Ubre Chico Stream and channels) in standing or slow-moving water.

Remarks. Pelocoris procurrens is one of the most widespread species of water bugs in the INR. This species was collected together with P. bipunctulus and P. politus . This is the first record of this species from INR. Pelocoris procurrens was previously recorded from Corrientes Province by López Ruf (1988, 1989, 1994b), Bachmann (1998), and López Ruf et al. (2003, 2006).
