Abstract
DE PAUL, Marcela A.; NIETO, Carolina and NEDER DE ROMAN, Lilia E.. Cloeodes incus (Waltz & McCafferty) (Ephemeroptera: Baetidae): frst record for Argentina, hydrologic and environmental remarks. Rev. Soc. Entomol. Argent. [online]. 2013, vol.72, n.3-4, pp.227-230. ISSN 0373-5680.
Cloeodes incus is recorded for the first time for Argentina. Nymphs were collected using Surber net and kick sampling in Pircas and Ajedrez rivers (Jujuy: Rinconada) at altitudes above 4000 masl. There were two annual field trips: at the end of the rainy season (April) and at the end of the dry season (November), during the years 2011 and 2012. This study allows extending the distribution of C. incus in the Central Andes and incorporates environmental and hydrological information of the selected sites. The highest values of density were obtained at the end of the dry season, with little amount of water and a pH of 7.1 to 8.1. Their presence was also recorded downstream of mining activities, with a pH of 3.7.
