DISCUSSION

Neivamyrmex carolinensis HNS is a wide ranging eastern species. Long considered to extend into the central and western United States as far as Arizona, it is now known that the populations west of the Mississippi River belong to a hitherto unrecognized sibling species. That species is described below as N. kiowapache HNS. We are unable to confirm the presence of this species in Nebraska and Ohio (M. R. Smith, 1942) nor have we seen any specimens from Louisiana.

This species is unusual among our species of Neivamyrmex HNS, in that the presence of a distinct eye facet is variable, present in some individuals, absent in others. Generally, a facet is present in larger individuals, but even this is subject to variation. This feature is shared with its sister species, N. kiowapache HNS.
