In South America, the European epi-endogeic lumbricid Octolasion cyaneum (Savigny, 1826) is known from Argentina, Chile, Brazil, Uruguay, and Ecuador. Here, we report this earthworm from Colombia for the first time. We found it in areas undergoing ecologic restoration in the Neusa Forest Reservoir, which is located in the department of Cundinamarca. Predominant vegetation in sampled areas is composed of Holcus lanatus, Hypochaeris radicata , and Anthoxanthum odorathum .
