Resumen

Three new species of the Andean genus Myrosmodes are described: Myrosmodes cleefi Szlach., Mytnik and S. Nowak, Myrosmodes reticulata Szlach., Mytnik and S. Nowak, and Myrosmodes subnivalis Szlach., Mytnik and S. Nowak. The former two species are known from a single population each, from Columbia, and the latter from Columbia and Ecuador. Each species is described and illustrated, and detailed habitat and distribution data are provided. A distribution map of the new species and the distribution range of the genus is presented. A dichotomous key for determination of the Andean species and Myrosmodes is provided. Conservation status assessments are provided for each species; current International Union for Conservation of Nature (IUCN) red list categories and criteria are listed. A brief discussion of endemism in the Andes and Tropical Andes biodiversity hotspot is presented.
