Abstract 

The subgenus Hagiomyrma Wheeler, 1911, of the genus Polyrhachis Fr. Smith, 1857, is revised. Forty-eight species are recognised, including sixteen previously described species: P. ammon (Fabricius), P. ammonoeides Roger, P. angusta Forel, P. crawleyi Forel, P. denticulata Karavaiev, P. lachesis Forel, P. lydiae Forel, P. metella Fr. Smith, P. paxilla Fr. Smith, P. penelope Forel, P. schenkii Forel, P. semiaurata Mayr, P. semiobscura Donisthorpe, P. thusnelda Forel, P. trapezoidea Mayr and P. tubifera Forel. Thirty-two species are described as new: P. anderseni, P. archeri, P. aurora, P. bohemia, P. brisbanensis, P. brutella, P. burwelli, P. callima, P. capeyorkensis, P. clarki, P. conciliata, P. cracenta, P. darlingtoni, P. diversa, P. dougcooki, P. electra, P. elegantula, P. feehani,P. hoffmanni, P. injinooi, P. isolata, P. melanura, P. nourlangie, P. pilbara, P. placida, P. seducta, P. stricta, P. tanami, P. tenebra, P. uncaria, P. vernoni and P. weiri. Six species-groups are recognised: P. ammon-group, metella-group, penelope-group, schenkii-group, trapezoidea-group and tubifera-group. Three species, Polyrhachis sokolova Forel, P. trophima Fr. Smith and P. xiphias Fr. Smith, formerly placed in Hagiomyrma are excluded and placed in different subgenera. A key based on the worker caste is provided. All species are illustrated and their known distributions and biology and ecology summarised.
