M. text Bulletin of the American Museum of Natural History 1922 45 39 269 http://plazi.org:8080/dspace/handle/10199/17097 journal article 20597 Polyrhachis (Myrma) militaris subspecies cupreopubescens variety dido , new name This name is suggested to replace argentatus Stitz , which is preoccupied by P. argentatus F. Smith [= Formica argentata Fabricius = P. sexspinosa (Latreille) ]. I possess two workers of this beautiful variety from Mt. Coffee, Liberia, collected by R. P. Currie. The thorax, petiole, coxae, and ventral portions of the gaster are covered with dense, brilliant, silver pubescence, the upper surface of the gaster with brilliant golden pubescence as in cupreopubescens . The lateral spines of the petiole are very short.
