Polyrhachis aruensis

Identification
Polyrhachis aruensis differs from Polyrhachis laevissima in having the mesosomal dorsum evenly convex in profile. The petiolar spines are very distinct, slender and acute and the subpetiolar process bluntly angular posteriorly. In contrast the profile of the mesosomal dorsum in Polyrhachis laevissima features a rather convex pronotum, with the mesonotum, propodeum and declivity descending posteriorly in a very weakly bowed line. The petiolar spines are rather short and blunt and the subpetiolar process is very weakly rounded posteriorly. (Kohout 2006)
