Polyrhachis manni

Identification
Polyrhachis manni is undoubtedly closely related to Polyrhachis lucidula Emery and to Polyrhachis ridleyi Forel. 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. For additional notes on the latter two species see Kohout (1998: 516).
