Polyrhachis captiva

Polyrhachis captiva is the only species of the gravis group known from Victoria. The single known specimen was collected in a pitfall trap on the top of an inland sand dune.

Identification
The unique holotype is a rather large specimen, distinguished from the other species of the group by its relatively large size, a pronotal dorsum with humeri produced into distinct, laminate, triangular teeth and weakly convex lateral margins (Fig. 2E) and a barrel-shaped propodeal dorsum. Postocullar process lacking and carina of dorsoanterior margin of first gastral segment only very weakly indicated. Pilosity very distinct, notably on dorsa of head, mesosoma, appendages and gaster, the later with hairs almost reaching in length the greatest diameter of eye; hairs are virtually absent from sides of mesosoma.

Distribution
This taxon was described from Australia.
