Key to Neoponera foetida species complex: Queens

This key to queens is based on: [[Media: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.pdf|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.
