Neivamyrmex andrei

Usually collected in forests, often in mesic sites. Males, the only known caste, were collected from late June to August.

Identification
In the United States: N. andrei may be separated from all other known United States species, except Neivamyrmex swainsonii, by the broad front coxae (in all our other species, they are distinctly longer than broad). We believe that Neivamyrmex agilis will prove to be the female castes of this species.
