- Biodiversidad de Heteroptera (Hemiptera) acuáticas y semiacuáticas de la Patagonia argentina María Cecilia MELO Biología Patagonia Argentina Aquatic and semiaquatic Heteroptera The aquatic and semiaquatic Heteroptera (infraorders Nepomorpha, Gerromorpha and Leptopodomorpha) show a low diversity in Argentina; up to now 208 species have been recorded. In 1881 Carlos Berg provided the first reference to Heteroptera from Patagonia (Río Negro). Since the early 60’s the aquatic Heteroptera have been studied by A.O. Bachmann and his students. Up to now there are 36 recorded species belonging to the families Corixidae, Notonectidae, Belostomatidae, Gelastocoridae, Naucoridae, and Nepidae (Nepomorpha); Hydrometridae, Veliidae, and Mesoveliidae (Gerromorpha), and Saldidae (Leptopodomorpha). Most of these species extend their geographic distribution to northern Argentina except Sigara (Tropocorixa) egbertae Hungerford, S. (T.) trimaculata (Le Guillou), S. (T.) vuriloche Bachmann, S. (T.) forciceps (Spinola), Trichocorixa milicorum Bachmann (Corixidae); Notonecta (Paranecta) virescens Blanchard, N. (P.) fazi Hungerford, N. (P.) vereertbruggheni Hungerford (Notonectidae); Pseudosaldula bergi (Haglund), P. paralia (Torres), P. angusta (Drake & Carvalho), P. sola (Drake & Carvalho), P. doeringi (Drake & Carvalho), and Saldula differata Drake & Carvalho (Saldidae), which are exclusive from Patagonia. The knowledge of the Patagonian aquatic and semiaquatic Heteroptera is accurate. According to the gathered data the state of conservation is acceptable; almost 40% of the species found in natural protected areas correspond to exclusive species from this region, representing almost the 40 % of the exclusive species from Patagonia. 2009 artículo científico 1851-7471 https://www.redalyc.org/articulo.oa?id=322028484012 es http://www.redalyc.org/revista.oa?id=3220 Revista de la Sociedad Entomológica Argentina application/pdf Sociedad Entomológica Argentina Revista de la Sociedad Entomológica Argentina (Argentina) Num.1-2 Vol.68
