This key to males is based on: Fernandes, I.O., De Oliveira, M.L. & Delabie, J.H.C. 2014. Description of two new species in the Neotropical Pachycondyla foetida complex (Hymenoptera: Formicidae: Ponerinae) and taxonomic notes on the genus. Myrmecological News 19, 133-163.

This key was published before Neoponera was revived as a genus. All of the species are in the genus Neoponera not Pachycondyla.

For more information about this species group please see the this page: Key to workers of foetida species complex.
