Polyrhachis manni

Specimens have been collected from 230-840 m, with one worker found in a malaise trap.

Identification
A member of the Polyrhachis mucronata  species group.

Kohout (2008a) - Polyrhachis manni is undoubtedly closely related to Polyrhachis lucidula and to Polyrhachis ridleyi. In addition to their similar general appearance, they all have rather broad petiolar spines. However, the spines in P. manni are distinctly less massive than in the other two species and the dorsum of the petiole bears two short, acute, intercalary spines that are lacking in both P. lucidula and P. ridleyi.

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