“…The studies of Archangelsky et al (2009), Merritt andCummins (1996), Bertrand (1972) and Leech and Chandler (1956) are noteworthy for quoting various genera found in Brazil. In recent years, studies related to taxonomy of water beetles (Spangler, 1990;Costa et al, 1996;Vanin and Costa, 2001;Benetti et al, 2006;Ferreira Junior et al, 2006;Passos et al, 2007;Braga and Ferreira Junior, 2009;Fernandes et al, 2010;Queney, 2010) and ecology (Benetti and Hamada, 2003;Passos et al, 2003a, b;Segura et al, 2007a, b) are increasing. However, because of the incipient stage of knowledge of the water beetles in the country, further studies are needed.…”
