A new species of Buenoa (Hemiptera: Heteroptera: Notonectidae) fromColombia

Abstract

Key words aquatic insects, high-Andean, south-west ColombiaIntroduction The genus Buenoa Kirkaldy has approximately 63 species and is restricted to the Western Hemisphere. In Colombia there are 14 species of Buenoa, and five species are located on the Pacific coast of Colombia in Tumaco, Nariño (PadillaGil, 2010). Buenoa funensis is described; it is the first record of the genus in high-Andean aquatic ecosystems, in the department of Nariño. In the department of Cundinamarca, Padilla-Gil (2002) found four species of Buenoa up to 1800 m above sea level, and just two species, B. pallipes (Fabricius) and B. cucunubensis Padilla-Gil & Nieser, were found at 3000 m. Buenoa funensis constitutes the first recording in Colombia of a large-size species, whose males measure more 8 mm of length; for this reason it is included within the five South American species and B. distincta from Mexico, which present this characteristic; and a key is presented to differentiate males and females of these species based on Nieser et al. (1997).
