Description
Kohout (2013b): Polyrhachis xiphias was described from a single queen and subsequently placed by Emery (1925: 185) in the subgenus Hagiomyrma. Only following the recent identification of worker specimens was P. xiphias recognised as a member of the subgenus Campomyrma Wheeler. It became the name-bearing species of the Polyrhachis xiphias-group (Kohout 2007: 7), a small group of species within Campomyrma, which also includes Polyrhachis hashimotoi Kohout from Borneo and Polyrhachis shixingensis Wu & Wang from China. The members of this group differ from other Campomyrma species by having the petiolar node columnar and the dorsum armed with two, more-or-less horizontal, posteriorly directed spines, in contrast to the scale-like petiole of all other known Campomyrma species.
