Polyrhachis darlingtoni

Polyrhachis darlingtoni is only known from two closely situated localities in the McIlwraith Range, along Leo Creek Road and at Lankelly Creek, near Coen on Cape York Peninsula.

Identification
Polyrhachis darlingtoni is easily identified by its low petiole with a strongly posteriorly descending, triangular dorsum and the bases of its rather short spines situated well below its widely rounded summit (Fig. 13B). The petiolar node of P. darlingtoni resembles that of Polyrhachis nourlangie, however in the latter species the petiolar dorsum is flat, laterally marginate, with the margins terminating in the bases of short, curved spines on the petiolar summit (Fig. 13D). The species also differ in their size, with P. darlingtoni consistently larger (HL 2.59-2.67 versus 1.62-2.09 in P. nourlangie), and in the colour of their pubescence which, in P. nourlangie is uniformly golden, lacking the brassy and reddish hues of P. darlingtoni.

Distribution
This taxon was described from Australia.
