Belostomatidae

Belostomatidae is the richest family of aquatic bugs in Argentina, with 31 described species in three genera ( Coscarón 2017). Belostoma nicaeum Estévez & Polhemus, 2007 and B. pygmaeum ( Dufour, 1863) were recorded from Argentina (Corrientes Province: Colonia Carlos Pellegrini, in INR) by Estévez et al. (2003) and Estévez & Armúa de Reyes (2003), respectively, which was repeated by Coscarón (2017). Estévez & Polhemus (2007) presented the distribution of these species without mentioning Argentina. Therefore, the records of B. nicaeum and B. pygmaeum from this country are not considered here. Poi de Neiff (1984, 1993, 2003), Armúa de Reyes & Estévez (1999, 2016), Estévez & Armúa de Reyes (2003), Estévez et al. (2003), Schnack & Estévez (2005) and Perez Goodwyn (2006) previously reported 14 species from INR, of which three were not collected during this study: Belostoma bosqi De Carlo, 1932 ; B. testaceopallidum Latreille, 1807 ; and Horvathinia pelocoroides Montandon, 1911 . During this study, we collected 11 species of Belostomatidae from INR, including three new records for this Reserve: Belostoma candidulum Montandon, 1903 ; B. discretum Montandon, 1903 ; and Lethocerus maximus De Carlo, 1938 . Seven species of Belostomatidae ( Belostoma bergi (Montandon, 1899) ; B. cummingsi De Carlo, 1935 ; B. gestroi Montandon, 1900 ; B. orbiculatum Estévez & Polhemus, 2011 ; B. oxyurum ( Dufour, 1863) ; B. retusum Estévez & Polhemus, 2001 ; Lethocerus bruchi De Carlo, 1931 ), reported from Corrientes Province ( De Carlo 1930, 1932, 1938, 1964b; Lauck 1964; Nieser 1975; Schnack 1976; Lanzer-de Souza 1980; Contartese & Bachmann 1987; Viscarret & Bachmann 1997; Bachmann 1998; Armúa de Reyes & Estévez 1999; Estévez & Polhemus 2001; López Ruf et al. 2003; Morrone et al. 2004; Ribeiro 2004, 2007; Perez Goodwyn 2006; Torres et al. 2007; Armúa de Reyes & Kehr 2008; Armúa de Reyes 2012; Chirino et al. 2013), have not been collected from INR.
