Myrmecologische Nachrichten 12: 255-272, URL: http://antbase.org/ants/publications/22836/22836.pdf Abstract The Palaearctic members of the Formica rufibarbis Fabricius, 1793 group were investigated by means of numeric morphology-based alpha-taxonomy (NUMOBAT). 496 nest samples comprising 1753 worker individuals were analysed in eighteen phenotypic characters and a further 330 samples for only ten characters. Nine morphospecies and one subspecies were recognised: Formica rufibarbis, F. cunicularia Latreille, 1798, F. clara Forel, 1886, F. clara sinae Emery, 1925 stat. n., F. glabridorsis Santschi, 1925, F. orangea sp. n., F. tarimica sp. n., F. anatolica sp. n., F. tianshanica sp. n., and F. persica sp. n. All nine morphospecies were convincingly separable from each other by discriminant analysis (DA) with an error prediction by a leave-one-out cross-validation of 0.4% in the worst case. Type samples of fourteen taxa were available and positioned near to the …
