Polyrhachis capeyorkensis

Identification
Polyrhachis capeyorkensis is similar to several species, but most notably to Polyrhachis lachesis, which is also a characteristic reddish-brown colour and clothed with bristle-like hairs. It differs by its generally smaller size (HL 1.65-1.90 in P. capeyorkensis versus 1.84-1.96 in P. lachesis), the form of its pronotal humeri which lack distinctly dilated, rounded prominences and the vertical carina running along the lateral margin of the posterior face of the petiole that is lacking in P. lachesis.
