Abstract

The species of the ant genus Nesomyrmex inhabiting the tropical dry forest (TDF) of Colombia are reviewed. Three new species of this genus, Nesomyrmex ikusp. nov., Nesomyrmex koninasp. nov., and Nesomyrmex xerophilussp. nov., are described based on worker caste. Nesomyrmex vargasi Longino, 2006 is recorded for the first time in South America, and Nesomyrmex antoniensis (Forel, 1912) is proposed as a junior synonym of Nesomyrmex asper (Mayr, 1887). A worker-based taxonomic identification key for the Colombian species is provided. High-resolution images and illustrations, and a distribution map for the species present in the Colombian TDF are provided.
