Three new species and reassessment of the rare Neotropical ant genus Leptanilloides (Hymenoptera Formicidae Leptanilloidinae)

摘要

We describe three new species of the Neotropical ant genus Leptanilloides: Leptanilloides gracilis >sp. n. based on workers from Mexico and Guatemala, Leptanilloides erinys >sp. n. based on workers and a gyne from Ecuador, and Leptanilloides femoralis >sp. n. based on workers from Venezuela. The description of Leptanilloides 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.
