Abstract

We describe three new species of the Neotropical ant genus Leptanilloides: L. gracilis sp. n. based on workers from Mexico and Guatemala, L. erinys sp. n. based on workers and a gyne from Ecuador, and L. femoralis sp. n. based on workers from Venezuela. The description of L. gracilis is a northern extension of the known range of the genus, now numbering eleven described species. We also describe and discuss three unassociated male morphotypes from Central America. We report the occurrence of a metatibial gland in Leptanilloides and a fused promesonotal connection (suture) in some species. We provide a modified, detailed diagnosis of the genus and a revised key to the worker caste of the known species.
