ABSTRACT
Four new records of species of aquatic heteropterous are added to the entomofauna of Colombia and, distributional limits are extended for all species collected. New data is reported for the distribution of 18 species, of which two belong to the infraorder Nepomorpha: Corixidae: Heterocorixa and Notonectidae: Martarega; 16 belong to Gerromorpha: of which 12 belong to the family Gerridae: Metrobates, Tachygerris, Limnogonus (two species), Brachymetra, Neogerris, Potamobates, Trepobates (three species), Telmatometra, Rheumatobates; three belong to the family Veliidae: Rhagovelia, Microvelia (two species), and one to Mesoveliidae: Mesovelia.
Key words: Aquatic insects; Corixidae; Notonectidae; Gerridae; Veliidae.

Introduction
]]> During the last years, the knowledge about aquatic heteropterous have widely increased, mainly with the description of new species of genera Rhagovelia, Paravelia, Tachygerris, Potamobates, Buenoa, and Martarega (Padilla-Gil 2009a, b; 2010, 2011a, b, c; 2012a, b, c; 2013a; Padilla-Gil and Nieser 2003; Padilla-Gil and Damgaard 2011; Padilla-Gil and Moreira 2011), most of species from south-western Colombia (Padilla-Gil and Arcos 2010; 2011; Padilla-Gil, 2012c, d), but information on several aspects of the biology of the species (Padilla-Gil 2013b), as their distribution (Padilla-Gil, 2013c; Padilla-Gil and Moreira 2013) among others, is still incomplete.Some faunal and taxonomic studies of aquatic heteropterous had been done in the Amazon region of Brazil such as Nieser (1970a, b, c, d), Estévez and Polhemus (2007), Moreira et al. (2008, 2009, 2011), and Barbosa et al. (2010).
The Colombian Amazon region begins on the eastern slope of the Cordillera Oriental and according to Mittermeier et al. (1999) that is the most biologically diverse "hot spot" in the world. However, in the region of Putumayo there are a few works about aquatic heteropterous, three species previously described with this type locality: two species of Buenoa (Notonectidae) (Padilla-Gil 2003) and one gerrid species, Potamobates sumaco Cognato, 1998.
This present study basically reports new information on the distribution of the aquatic heteropterous inhabiting freshwater bodies from the western Andean foothills of the Amazon, a region located in transition zone between the Colombian Amazon lowlands and the Andes. Given its aquatic biodiversity, fish resources, and fresh water ecosystems, this region is considered of the utmost importance for conservation strategies, potential management options, and increase environmental sustainability (Porro et al. 2008).
Material and methods
Specimens were obtained during field trips carried out in the localities showed in the map (Fig. 1) in the Colombian Putumayo River basin. Insects were collected with entomological hand nets sweeping the water column, edges and bottom of the water. The species were identified following Heckman (2011); the specimens collected were preserved in alcohol 70%, and deposited in the entomological collection of the Universidad de Nariño (PSO-CZ). The following abbreviations are used: apterous (apt) and macropterous (macr).
