It was collected together with  P. bipunctulusand  P. procurrens.This is the first record of this species from INR.  Pelocoris polituswas previously recorded from Corrientes Provinceby López Ruf (1988, 1992, 1994b) and López Ruf et al.(2006). 3697307548 [557,1227,290,316] 2013-04-17 Luna Lagoon Isiri Stream 36 487 1 1 3697307379 2013-04-19 Luna Lagoon Isiri Stream 36 487 3 3 3697307400 [627,1311,326,353] 2014-03-28 -28.698668 Itati Lagoon 12 -58.108166 36 487 2 1 1 3697307457 2014-03-29 -28.712166 Itati Rincon Island 12 -58.1115 36 487 6 2 4 3697307575 [787,1432,362,389] 2014-03-30 -28.736334 Corriente River 12 -58.145 36 487 3 3 3697307443 [382,1099,398,425] 2012-12-01 -28.567762 Ibera Lagoon 1 -57.189487 36 487 1 1 3697307476 2012-12-02 -28.536642 Corriente Stream 1 -57.211933 36 487 3 1 2 3697307598 2013-12-14 -28.1811 Carambola Stream 1 -57.437065 36 487 1 1 3697307585 [705,1432,506,533] 2013-12-14 -28.2435 Carambola Stream 1 -57.439632 36 487 1 1 3697307494 [326,1311,542,569] 2015-11-06 -28.428026 Campo Angelita 1 -57.820084 36 487 9 6 3 3697307469 2015-11-06 -28.400694 Paso Batalla 1 -57.88236 36 487 1 1 3697307429 2015-11-07 -28.56461 Medina Lagoon 1 -57.757973 36 487 4 1 3 3697307326 [448,1339,614,641] 2015-11-08 -28.400944 Caaby Aguilar 1 -57.858692 36 487 1 1
