Crust. Ins., 144–145. General distribution. Brazil , Argentina ( Moreira et al. 2011b ). Habitat. Belostoma testaceopallidum has been found in a shaded artificial reservoir, a small puddle, waterholes along a dry stream, the quiet edges of a stream (shallow and exposed to sunlight), and in a river with vegetated margins ( Vianna & Melo 2003 ; Pelli et al. 2006 ; Ribeiro 2005 , 2007 ). At the INR, B. testaceopallidum was collected from the margins of lentic habitats with dense floating, emergent, and submerged vegetation (Estévez & Armúa de Reyes 2003, as B. grandicollum De Carlo, 1934 ; Estévez et al. 2003, as B. grandicollum ) .
