San Ignacio RS: 4 ♂ , 2 ♀ , Camping Monterrey, Aguará pedestrian path, long walkway, marshes, 27°52’14.58’’S , 56°52’59.76’’W , 18.xi.2018 . Yahaveré RS: 1 ♂ , Caaby Aguilar, roadside marshes, 28°24’03.4”S , 57°51’31.3”W , 8.xi.2015 . General distribution. Argentina ( Bachmann & López Ruf 1994 ). Habitat. Neoplea argentina has been found in lagoons, lakes, marshes, and in standing or slow-moving water of streams and rivers ( Merlassino & Schnack 1979 ; Poi de Neiff 1983 ; Bachmann & López Ruf 1994 ; Poi de Neiff & Neiff 2006 ; Fontanarrosa et al. 2013 ). This species was previously recorded from Iberá in association with Egeria najas , Salvinia biloba and Potamogeton sp. ( Poi de Neiff 1993 , 2003 ). During the present study, it was collected from marshes with dense floating, emergent and submerged vegetation (mainly S. biloba ) in unshaded and shaded areas. This species was collected in association with the above mentioned vegetation in the Paraná River ( Argentina ) ( Poi de Neiff & Neiff 2006 ). Remarks. Neoplea argentina was collected in INR together with N. maculosa . The records from Brazil need confirmation ( Bachmann 1968 ; Nieser & Melo 1997 ; Heckman 1998 ; Souza et al. 2006 ).
