“…The distribution of Odonata fauna in Brazil is poorly known and only 29% of the Brazilian territory presents data on richness, concentrated mainly in the southern and southeastern regions (De Marco & Viana, 2005), with 828 recognized species (Costa, Santos, & Oldrini, 2012). For the Mato Grosso do Sul, the knowledge about the richness of Odonata is concentrated mainly in the Pantanal region (Longfield, 1929, Santos, 1944, Souza, Costa, & Santos, 1999, Souza, Costa, & Espindola, 2002, Souza & Costa 2006, Heckman, 2006, Pessacq & Costa 2007, Heckman, 2008, Dalzochio, Costa, & Uchôa, 2011a, Dalzochio, Souza, Uchôa, & Costa, 2011b. Specifically, for the Iguatemi River basin, a study with this approach was performed only at streams of the lower stretch of this basin (see Soares et al, 2015).…”
