New records of Ephemeroptera from the Colombian Orinoco river basin of the Meta department

Abstract

There is extensive research of the Ephemeroptera communities taxonomy and ecology in the Andean region of Colombia. However, other regions such as the Orinoquia have been insufficiently studied. From this region, in the Meta department, four species have been registered: Varipes lasiobrachius Lugo-Ortiz & McCafferty, Coryphorus aquilus Peters, Miroculis (Atroari) colombiensis Savage & Peters and Tricorythopsis rondoniensis (Dias, Cruz & Ferreira). The main objective of this study is to report for the first time for this region the species: Mayobaetis ellenae (Mayo), Hydrosmylodon primanus (Eaton), Haplohyphes baritu Domínguez, Camelobaetidus edmundsi Dominique, Mathuriau & Thomas and Nanomis galera Lugo-Ortiz & McCafferty.

Effects of physical and chemical factors on Ephemeroptera (Insecta) assemblages in an urban river of the eastern Colombian Llanos

“…Taxonomic composition of the Ephemeroptera assembly: There are nine Ephemeroptera families reported for Colombia (Salles et al, 2020), four were recorded in this study: Baetidae, Leptohyphidae, Leptophlebiidae and Caenidae. These correspond to 44.4% of registered families in the country and they have the largest number of genera and species recorded (Dias et al, 2009;Forero-Céspedes et al, 2014;García et al, 2013;Gutiérrez & Reinoso-Flórez, 2010;Gutiérrez et al, 2013;Gutiérrez & Llano, 2015;Hoyos et al, 2014;Molineri, 2014;Molineri et al, 2011;Motta-Díaz et al, 2012;Rozo & Salinas, 2016;Salinas et al, 2011Salinas et al, , 2012Salinas et al, , 2013Salinas-Jiménez et al, 2017Vinasco-Mondragón & Zúñiga, 2016;Zúñiga et al, 2014Zúñiga & Torres-Zambrano, 2015). Baetidae and Leptohyphidae were the most abundant and frequent in the different sampling stations, similar to what was found by Zamora (2015) in Orinoquia piedmont streams, where he further reported Leptophlebiidae and Oligoneuriidae.…”

“…In this work three new registers of genera are reported for the Meta department: Cloeodes, Lumahyphes and Zelusia. Until now, 18 genera and 11 species were reported for this department (Dias et al, 2009;Salinas-Jiménez et al, 2017Zamora, 2015;Zúñiga & Torres-Zambrano, 2015). With this research the genera registered increases to 21, which correspond to 38% of the approximately 55 genera recorded in Colombia (Dias et al, 2009;Forero-Céspedes et al, 2014;García et al, 2013;Gutiérrez & Reinoso-Flórez, 2010;Gutiérrez et al, 2013;Gutiérrez & Llano, 2015;Hoyos et al, 2014;Molineri, 2014;Molineri et al, 2011;Motta-Díaz et al, 2012;Rozo & Salinas, 2016;Salinas et al, 2011Salinas et al, , 2012Salinas et al, , 2013Salinas-Jiménez et al, 2017Zúñiga et al, 2014Zúñiga & Torres-Zambrano, 2015).…”

A new species of Camelobaetidius Demoulin, 1966 (Ephemeroptera: Baetidae), from the Colombian Orinoco River basin

“…In Colombia three species have been reported until now based on nymphs: Camelobaetidius edmundsi Dominique, Thomas & Mathuriau, 2001; Camelobaetidius mathuriae Dominique & Thomas, 2001;Camelobaetidius patricki Dominique & Thomas, 2001(Dominique, Mathuriau & Thomas, 2001Salinas et al 2012;Salinas et al 2017). The aim of the present paper is to describe a new species of Camelobaetidius based on nymphs from the Colombian Orinoco River basin.…”
