Nomenclature

The following information is derived from Barry Bolton's New General Catalogue, a catalogue of the world's ants.

  • pallescens. Plagiolepis pygmaea var. pallescens Forel, 1889: 265 (w.) GREECE. Santschi, 1911i: 287 (q.); Finzi, 1928c: 790 (m.). Subspecies of pygmaea: Ruzsky, 1902d: 18; Santschi, 1920g: 168. Raised to species: Emery, 1921d: 315; Finzi, 1928c: 790; Karavaiev, 1931a: 311. Current subspecies: nominal plus atlantis, elguerrhae, isis, kabyla, maura, polygyna, sordida. See also: Menozzi, 1936d: 297.

Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.
