Checklist and distribution of semiaquatic and aquatic Heteroptera (Gerromorpha and Nepomorpha) occurring in Brazil 2958 Author Moreira, Felipe Ferraz Figueiredo Author Barbosa, Julianna Freires Author Ribeiro, José Ricardo Inacio Author Alecrim, Viviani Pereira text Zootaxa 2011 2011-07-08 2958 1 1 74 https://biotaxa.org/Zootaxa/article/view/zootaxa.2958.1.1 journal article 10.11646/zootaxa.2958.1.1 1175­5334 5281851 Belostoma anurum (Herrich-Schäffer, 1848) Geographical distribution: Martinique , St. Vincent & Grenadines , Colombia , Grenada , Trinidad & Tobago , French Guiana , Brazil , Ecuador , Chile , Argentina , and Uruguay . Records north of those presented above are highly doubtful and not considered here. Distribution in Brazil : Northeast, Central-West, Southeast and South regions (MA, CE, RN, BA, AL, DF, MG, ES, SP, RJ, SC) ( Ribeiro 2007 ). Comments: Some of the B. anurum specimens studied so far do not differ from B. subspinosum (Palisot de Beauvois, 1805) subspecies in features of the phallus, and B. anurum might eventually prove to be a junior-synonym of B. subspinosum .
