title: New records of Gerromorpha and Nepomorpha (Insecta: Hemiptera: Heteroptera) from South America.
abstract: BACKGROUND
  Aquatic and semiaquatic Heteroptera occur on all continents except Antarctica and occupy a wide variety of habitats, including lentic and lotic water bodies, perennial or temporary. In the Neotropical Region, there is a lack of knowledge concerning the geographical distribution of most represented species, which can only be solved by the collection of specimens in under-studied areas and publication of new records and lists of species.
  
  
  CONCLUSIONS
  New records are presented for eleven species of Gerromorpha and ten Nepomorpha, including first records from Venezuela (Brachymetra lata, Limnogonus hyalinus, Rhagovelia evidis, Tenagobia peruana, Limnocoris burmeisteri, L. fittkaui fittkaui, Placomerus micans, and Martarega gonostyla), the Venezuelan State of Bolívar (Cylindrostethus palmaris, R. elegans, R. tenuipes, and Ambrysus stali), the Brazilian State of Bahia (Martarega bentoi), Peru (Euvelia lata), and the Peruvian Region of Arequipa (Microvelia pulchella).
