Ephemeroptera (Insecta) de caldas - Colombia, claves taxonomicas para los generos y notas sobre su distribucion

Abstract

With the aim of contribute to the knowledge of taxonomy and distribution of the genera of the order Ephemeroptera in Caldas, samples were taken between May of2008 and May of 2012 in 12 municipalities of the department of Caldas — Colombia, covering an altitudinal range from 159 to 3433 m and a total of 55 water sources. Six families and 26 genera of Ephemeroptera were found, of which Cabecar is a new record for Colombia, also recording for the first time the nymphs of Tikuna and Ulmeritoides for the country. Americabaetis, Apobae-tis, Callibaetis, Cloeodes, Guajirolus, Paracloeodes, Cabecar, Traveryphes, Tricorythodes, Terpides, Tikuna, Ulmeritoides, Caenis and Campsurus are new records for Caldas. Differences in the composition of the fauna in the diverse altitudinal zones were found, being the areas below 1000 m with highest genera richness.
