Based on an examination of 187 specimens, five new species of Argyrotaenia are recognized from Mexico and the south western United States. A hypothesis of the phylogenetic relationships among the species is derived using Hennig86 to find the most paJ'simo nious solution to the distribution of 14 morpholOgical characters (5 characters of the forewing, 7 of the male genitalia, and 2 of the female gen italia). Argyrotaenia spinacallis Brown & Cramer, new species, from the State of Veracruz, A. unda Brown & Cramer, new species, from the states of Mexico and Morelos, and A. octavana Brown & Cramer, from the states of Puebla and Veracruz, appear to form a monophyletic group with A. ponera (Walsingham), from Puebla. The last is redescribed and illustrated. Although superficially similar, A. coconinana Brown & Cramer, new species, from Arizona and New Mexico, and A. bialbistriata Brown & Cramer, from Arizona (Cochise Co.) and Durango, Mexico, may not be members of the "ponera group" owing to their considerable divergence in male and female genitalia. Additional key words: phylogeny, ponera group, morphology, genitalia. With the exception of a single widespread Palaearc sonian Institution, Washington, DC.
