Polyrhachis abdominalis

Specimens from Sulawesi have been collected from fogging samples, with some of these noted from cacao agroforest.

Identification
A member of the Polyrhachis hector species group.

Kohout (2008) - Specimens of Polyrhachis hector feature a set of distinct, spur-like spines along the inner edge of the hind tibia, that are lacking in P. abdominalis. The latter species is also distinctly more slender.

Distribution based on Regional Taxon Lists
Indo-Australian Region: Borneo, Indonesia, Krakatau Islands, Malaysia, Philippines. Oriental Region: India, Laos, Myanmar, Thailand.
