Nothing is known about the biology of Polyrhachis celebensis.
Identification
Kohout (2008) - Polyrhachis celebensis is very similar to Polyrhachis fornicata. Both species have a virtually identical petiole with slender and acute dorsal spines with their tips curved backwards, while the lateral spines are very short, reduced to mere angles. In lateral view the mesosoma of both species is quite similar, featuring a moderately convex pronotum and a distinct step in the mesosomal outline, indicating the position of the metanotal groove. However, the propodeal declivity in P. celebensis is steeply oblique, while in P. fornicata it is virtually vertical. The main difference between the species is the shape of their pronotal humeri that, in P. celebensis are somewhat angulate, while in P. fornicata they are narrowly rounded.
Kohout (2006) - Characterised by angular pronotal shoulders armed with diminutive denticles, a petiole armed with four spines (the dorsal pair rather prominent and slightly longer than the lateral pair) and black legs. In contrast, the pronotal shoulders in Polyrhachis rastellata are narrowly rounded, the petiolar spines subequal in length and the legs distinctly orange or light reddish-brown.

Description
Worker
Unterscheidet sich von der Stammform nur durch die weniger abgerundeten Vorderecken des Pronotums (fast wie bei levior), die die schwache Andeutung eines ab gerundeten Zahnchens zeigen.
