General distribution. Colombia , Brazil , Paraguay , Argentina ( Moreira et al. 2011b ). Habitat. Pelocoris politus has been found in rivers and lagoons ( Roback & Nieser 1974 ; Nieser 1975 ; López Ruf 1988 , 1992 , 1994b ). At the INR, P. politus was collected from unshaded margins with dense floating, emergent and submerged vegetation (mainly Azolla filiculoides , Pontederia azurea , P. cordata , Myriophyllum aquaticum , Hydrocleys nymphoides and Salvinia biloba ) in lentic habitats (Iberá Lagoon, Fernández Lagoon, Medina Lagoon, Itatí Lagoon, marshes, marshlands and ditches), and lotic habitats (Corriente Stream, Isirí Stream, Carambola Stream and Corriente River) in standing or slow-moving water. Remarks. Pelocoris politus is one of the most widespread species of water bugs in the INR. It was collected together with P. bipunctulus and P. procurrens . This is the first record of this species from INR. Pelocoris politus was previously recorded from Corrientes Province by López Ruf (1988 , 1992 , 1994b ) and López Ruf et al. (2006) .
