Nothing is known about the biology of Polyrhachis wagneri.
Identification
Polyrhachis wagneri is relatively similar to Polyrhachis leonidas from the Bismarck Archipelago from which it differs by a distinctly smaller head, higher and more convex pronotum and very short, tooth-like propodeal spines. The petiole is exceptionally broad with widely diverging lateral spines. (Kohout 2006)
Keys including this Species
Distribution
Polyrhachis wagneri appears to be rare, with only one recent specimen, collected by R.W. Taylor at Yawasora nr Wewak (East Sepik Province, Papua New Guinea), available for examination. (Kohout 2006)
