Eciton harrisi   HNS   : Forel, 1899: 28 (m).

Eciton (Acamatus) harrisi   HNS   : Emery, 1900: 515; fig. 18.

Neivamyrmex wheeleri   HNS   : Borgmeier, 1953: 6. 1955: 511 - 514; (q, w).

Neivamyrmex harrisi   HNS   : Borgmeier, 1955: 522 - 524. Watkins, 1968: 275.


UNITED STATES: Oklahoma and Texas, west to Arizona; MEXICO: border states south at least to Colima in the east and Nayarit in the west.


We have studied 141 samples of this common species from the United States and Mexico.


M. R. Smith (1942) opined that N. wheeleri   HNS   represented the female castes of N. harrisii   HNS   . This suspected synonymy was confirmed by Watkins (1968).

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