A brief look at the Odonata from the Páramo ecosystems in Colombia, with the descriptions of Oxyallagma colombianum sp. nov. and Rhionaeschna caligo sp. nov. (Odonata: Coenagrionidae, Aeshnidae, Libellulidae) Author Bota, Cornelio Andrés text Zootaxa 2014 3856 2 192 210 journal article 10.11646/zootaxa.3856.2.2 24c01b66-c0d2-458b-a7fe-0e3de779a8e8 1175-5326 250932 ABC0E7D7-2E22-4605-A97B-0F1E632F3930 Oxyallagma genus The only species known so far in this genus is Oxyallagma dissidens (Selys, 1876) from Ecuador and Peru . The presence of Oxyallagma in Colombia was previously mentioned by Bota - Sierra & Wolf (2013) ; however, they only mentioned an undescribed species sympatric with M. gaudiimontanum . Here I present a key to distinguish the two species that inhabit the Colombian Andes.
