Polyrhachis varicolor

Identification
Kohout (2008) - Polyrhachis fruhstorferi is similar to P. fruhstorferi varicolor. The sculpturation in both species consists of reticulate-punctation, however, it is distinctly finer in P. varicolor. The petiolar spines in P. varicolor are longer and more slender, while in P. fruhstorferi they are rather stubby. The colour of the body in P. fruhstorferi is mostly black, with only the legs and gaster very dark reddish-brown. In contrast, the body of P. varicolor, including the antennae and legs, is distinctly orange or light reddish-brown with the tarsi, gaster and apices of the petiolar spines darker reddish-brown and the frontal carinae and lateral margins of mesosoma narrowly lined with dark brown.
