Identification
Key to the Neivamyrmex species of the United States

Males of this common species are regularly collected at lights. They are superficially similar to those of Neivamyrmex andrei but the mandibular shape and the large ocelli will serve to separate them from that species. (Snelling and Snelling 2007)
