Polyrhachis albertisi

Nothing is known about the biology of Polyrhachis albertisi.

Identification
Characterised by distinctly toothed or bilobed pronotal humeri and closely resembles Polyrhachis levior, with the mesosomal structure similar in both species. However, the humeral prominences are nearly equal in Polyrhachis levior, while in Polyrhachis albertisi the anterior lobe forms a blunt, but distinct tooth (similar to that in Polyrhachis aruensis) and the posterior lobe is only weakly defined. The propodeal spines in Polyrhachis albertisi are short and strongly upturned, while in Polyrhachis levior they are longer, more massive and somewhat dorso-ventrally compressed. (Kohout 2006)
