ABSTRACT: The United States species of Neivamyrmex are here reviewed. The following new synonymy is proposed (senior synonym listed first): N. moseri Watkins = N. isodentatus Mackay; N. swainsoni (Shuckard) = N. mexicanus (F. Smith) = N. fallax Borgmeier; N. halidaii (Shuckard) = N. mexicanus (E. V. Enzmann), not N. mexicanus (F. Smith). N. mandibularis (M. R. Smith) is elevated to species level, new status, having previously been regarded as a subspecies of N. pilosus (F. Smith). One species, N. graciellae (Mann) is recorded from the United States (Arizona) for the first time. Four new species are described: N. goyahkla (southern Arizona; workers only), N. kiowapache (Kansas to southern Arizona; all castes), N. ndeh (southern Arizona; males only) and N. wilsoni (southern California; workers). New keys are presented for the separation of worker and male castes of all known United States species, and most species are illustrated.
