Neivamyrmex is a genus of army ants in the subfamily Dorylinae.[2]

Range

Neivamyrmex species can be found from the central United States to southern Argentina.[3]

Taxonomy

As of 2021, 129 Neivamyrmex species have been identified.[3] However, most research pertaining to this genus is based on a single species, Neivamyrmex nigriscens, from which knowledge about Neivamyrmex overall is derived.[3] Many species are known based only on a small number of male individuals.[3]

Biology

Neivamyrmex do not build permanent nests; instead, colonies are nomadic, establishing temporary bivouacs every night before moving on to a new location.[4] Most species are predominantly subterranean, but they will occasionally forage above ground at night or on cloudy days.[5] The larvae and pupae of other ant species are the principle food of Neivamyrmex, including ants of the genera Veromessor, Pheidole, Solenopsis, and Formica.[6]

Neivamyrmex nigrescens worker

Male Neivamyrmex possess wings, while queens are flightless.[7] Fertilization of queens may occur purely within the colony, with mating occurring between brothers and sisters, or unrelated males may fly in from foreign colonies to reproduce.[7] After being fertilized, new queens will found new colonies by leaving their natal colonies alongside a large number of workers.[7]
