| Polyrhachis pressa|
Specimens have been collected from fogging samples in forest with a cacao understory.
A member of the Polyrhachis hector species group.
Kohout (2008) - Sulawesian specimens are generally smaller than those from Java and Borneo (HL 2.15-2.46 versus HL 2.40-2.68) but they are otherwise identical.
Keys including this Species
Kohout (2008) - This is a very characteristic, relatively rare species that is known from both Java and Borneo. It was reported from Sulawesi by Emery (1901: 569) but the workers from Lore Lindu and Dumoga-Bone National Parks are the only specimens I have seen from the island.
