Abstract

Two species of Arzecla Duarte et Robbins, 2010 are described from Colombia, namely: Arzecla straboris Bálint, sp. n. (type locality: El Aguila, Manizales, Caldas), and Arzecla straelena Bálint, sp. n. (type locality: Cerro Ingrumá, Riosucio, Caldas), both on the basis of a single male specimen. New species possess a combination of characters, unique in the genus, hence they are easy to identify. A checklist with biogeographic and country indications and a key for identification based on wing characters for all described Arzecla species is provided. Specimens examined for comparative purpose are listed as an Appendix. Eleven figures.
