Abstract

The limata species complex of the genus Crematogaster encompasses ants with an elongated petiole that gradually narrows towards the anterior margin (dorsal view), a smooth and shining face, with abundant long erect setae, and well-developed propodeal spines. This complex of species is restricted to the Neotropical Region, and is common in arboreal environments of primary and secondary forests, agricultural ecosystems, and even human-modified environments, where they can be locally abundant. Currently, the complex comprises 20 species from southern Mexico to Paraguay and southern Brazil, nesting mainly in twigs, litter, and under bark. Here, we describe six new species from Colombia: C. labalsa, C. orito, C. protzalezi, C. quipile, C. tequendama, and C. vega, based on the worker caste. Additionally, we provide an identification key and original descriptions, including comparisons with the closest species.
