Abstract

PADILLA GIL, Dora Nancy. Diversity of the Genus Rhagovelia (Hemiptera: Heteroptera: Veliidae) from Andean-Amazon Piedmont (Putumayo, Colombia). Acta biol.Colomb. [online]. 2019, vol.24, n.1, pp.174-179. ISSN 0120-548X.  https://doi.org/10.15446/abc.v24n1.66352.

The purpose of this work was to determine the composition, diversity, abundance, and geographic and altitudinal distribution of the species of genus Rhagovelia from lotic ecosystems in the municipalities of Orito, La Hormiga and San Miguel (altitudinal range 310 to 620 m asl) belonging to Andean-Amazon piedmont. Samples were collected in June 2017, using entomological nets. As a result there were determined six species of the genus Rhagovelia, the diversity indices showed high values (Shannon-Wiener: 1,43, Simpson: 3,61 and Margalef: 0,76) that indicate the diversity and high number of individuals for specie; R. mocoa (38 %) and R. spinosa (31 %) were the most abundant species. Additionally the results were compared with the Upper basin of the Putumayo River, Mocoa-Puerto Asis municipalities.

Keywords : Amazonian basin; Cordillera Oriental; semiaquatic insects; South America.
