Type-species

Eciton (Acamatus) schmitti (junior synonym of Labidus nigrescens), by subsequent designation of Ashmead, 1906.
Neivamyrmex is the most species-rich and widely distributed genus of New World army ants. The biology of the vast majority of the 130 described species is unknown, but Neivamyrmex nigrescens has become one of the best studied dorylines.

Diagnosis

Worker. Neivamyrmex have 12-segmented antennae, propodeal spiracle high on the sclerite, lack conspicuous propodeal lobes, pygidium small and without a central impressed field, waist two-segmented, and pretarsal claws without a tooth. The simple claws distinguish Neivamyrmex workers from all other New World army ant genera (Cheliomyrmex, Eciton, Labidus, and Nomamyrmex). Aenictus in the Old World will also match some of these diagnostic characters but workers of this genus never have more than 10 antennal segments.
Male. Neivamyrmex males share the army ant-like habitus with other members of the Eciton genus-group. See discussion under Cheliomyrmex male diagnosis for characters differentiating New World army ant males from those of the Old World. Among the New World army ants, Neivamyrmex can most reliably distinguished by a combination of apex penisvalvae without setae, no dense setation on gaster, and abdominal segment II (petiole) without a deeply notched or concave surface. The bare penisvalvae are shared only with Eciton and Nomamyrmex but the former always has a deeply excavated petiole and the latter has conspicuous tufts of dense setae on the gaster.

Taxonomy and phylogeny

First species now classified in Neivamyrmex were described from males by William Shuckard in his 1840 series ‘Monograph of the Dorylidae’. Borgmeier later erected the genus (Borgmeier 1940[4]) and cemented its future use with his classification of New World army ants presented in his monographs (Borgmeier 1953[5], 1955[6]). Borgmeier (1955)[6] also presented an internal classification for the genus with fourteen informal species groups, including five based solely on males as, typically for army ants, numerous names have been proposed for males without associations with workers. Later work on Neivamyrmex taxonomy has been dominated by Julian Watkins who published many new isolated species descriptions and also provided updated identification resources for this and other New World army ant genera, first for New World in general (Watkins 1976[7]) and later for United States in particular (Watkins 1985). This latter resource was recently updated with a publication by Snelling and Snelling (2007)[8]. Neivamyrmex is the most species-rich of the Eciton genus-group with 127 extant species. The genus is the sister group to the clade of the other four New World army ant genera and is monophyletic (Borowiec, in prep.). There is no comprehensive internal phylogeny, but preliminary data indicates that some of the species groups proposed by Borgmeier are not monophyletic (Borowiec, in prep.).

Biology

The majority of species has never been studied in any detail, and much of what we know comes from the observations made on one relatively common species, Neivamyrmex nigrescens, studied extensively by Howard Topoff and his students (Gotwald 1995[9]). The biology of other species has been summarized by Rettenmeyer (1963)[10].
If Neivamyrmex nigrescens is representative of this genus, the lineage’s habits are similar to those of other New World army ants. There are marked nomadic and statary phases, lasting about 16 and 20 days, respectively. The colonies are of moderate size, containing 80,000 to 140,000 workers (Rettenmeyer 1963[10]; Topoff et al. 1980[11] estimate 10,000–50,000) and bivouacs are subterranean. The prey consists of almost exclusively other ants’ brood.
Nesting sites of Neivamyrmex are rarely observed. Rettenmeyer (1963)[10] reported that although known bivouac sites of Neivamyrmex nigrescens in Kansas are typically at least 1 meter below the surface, two bivouacs were discovered that were completely contained within the upper 30 cm of the soil. Emigration behavior in this species has been very well described. Environmental factors, such as prey availability/density and nest site availability, influence the emigration behavior (Topoff and Mirenda 1980[12], Mirenda and Topoff 1980[13]). Neivamyrmex carolinensis and Neivamyrmex kiowapache are unusual among army ants in that they are the only species known to be polygynous, with colonies reported to contain over a dozen queens (Rettenmeyer and Watkins 1978[14], see also Snelling and Snelling 2007[8]). The queens of Neivamyrmex kiowapache have been shown to mate with much lower frequency than other army ants. This is in accordance with the prediction that the costly multiple matings will be reduced or lost if genetic diversity of workers can be achieved through polygyny (Kronauer and Boomsma 2007b[15]).
The foraging biology of Neivamyrmex nigrescens in Arizona was studied in detail by Mirenda et al. (1980)[16]. They reported that these army ants forage at night and raid nests of many other ants and termites. The ants in the genus Pheidole were shown to be the preferred prey, being taken twice as often as expected based on colony density. Pogonomyrmex, Forelius, and Myrmecocystus were reported to be avoided. The authors observed temporal variation in prey composition, noting that as the season progressed and conditions became drier, many of the prey Pheidole species ceased activity and sealed their nests. Neivamyrmex nigrescens was then observed to rely more heavily on Novomessor cockerelli as prey.
Several Neivamyrmex species can occur sympatrically, and it is likely that a diversity of prey preferences exists in the genus. Mirenda et al. (1980)[16] also observed multiple raids of Neivamyrmex harrisii, sympatric with Neivamyrmex nigrescens, and noted that Solenopsis xyloni was the only species being attacked.
Neivamyrmex nigrescens uses both tactile and chemical cues in orientation (Topoff and Lawson 1979[17]).
Many species of ants respond to a Neivamyrmex attack by nest evacuation and this behavior has been highlighted as a tool for collecting colonies of soil-nesting species that are normally difficult to excavate. Smith and Haight (2008)[18] showed that 150-300 Neivamyrmex nigrescens workers poured into the nest entrance of Novomessor cockerelli induced evacuation of a mature colony, including brood and queen.
