The collections of Nomamyrmex  that I have examined from Paraguay fall neatly into two species corresponding most commonly to N. esenbeckii  and more rarely to N. hartigii  . Watkins (1976) and Borgmeier (1955) provide characters to separate the species.

In contrast, literature records of Nomamyrmex  from Paraguay pertain to three forms, N. hartigii  (Borgmeier 1955, Santschi 1916), N. esenbeckii  (Borgmeier 1955, Santschi 1929 a), and N. esenbeckii crassicornis  (Forel 1906, Forel 1908 b, Forel 1909). The literature records of N. esenbeckii crassicornis  , a subspecies generally known from the more tropical regions of South America, are based on Forel’s identifications. Thus, the presence of three forms in the literature is likely an artifact of differing conceptions on the part of earlier taxonomists. Regardless of these conceptual differences, the subspecies of N. esenbeckii  are largely allopatric across the Neotropics (Watkins 1976). Gordon Snelling, who has examined material from throughout the region, provides a detailed case for the synonymy of all of them at www.armyants.org. I concur with Snelling’s reasoning and synonymize N. crassicornis  under N. esenbeckii  here.
