Polyrhachis aequalis

Identification
A member of the Polyrhachis aequalis species group.

Kohout (2008) - Polyrhachis frauenfeldi and Polyrhachis aequalis are very similar. Both species have short, but distinct humeral teeth, almost identical sculpturation of the mesosomal dorsum, subequal petiolar spines and a reddish-brown body and appendages. They mainly differ in the form of the median portion of the anterior clypeal margin that, in P. ternatae, has a widely open, V-shaped emargination, while it is simply truncate in P. aequalis.

Distribution based on Regional Taxon Lists
Indo-Australian Region: Borneo, Indonesia, Malaysia, Philippines.
