| Polyrhachis amana|
Smith, F., 1861
Specimens have been collected from fogging samples in natural forest.
A member of the Polyrhachis mucronata species group.
Kohout (2008) - The specimens from Dumoga-Bone (Sulawesi) are larger than the syntype examined (HL 1.90-2.00 versus HL 1.75 in a syntype) and differ in a number of characters. The clypeus in lateral view is distinctly sinuate in modern specimens, while in the syntypes it is virtually straight anteriorly and deeply impressed basally. The lateral outline of mesosoma of the modern specimens is moderately convex with its highest point located just behind the promesonotal suture. The mesosomal outline in the syntypes is more strongly convex with the highest point at the promesonotal suture itself. In the modern specimens the pronotal and propodeal spines are more divergent, the base of petiolar node in profile is broader and the petiolar spines are less elevated and almost straight. In the syntype the tips of the petiolar spines are slightly bent downwards. The colour of the body and appendages in modern specimens is uniformly black, with only the coxae and the proximal ends of femora reddish-brown. The body and most of the antennal scapes of the syntype are black, with the legs and antennal funiculi generally light to medium yellowish-brown. In spite of these differences I consider the modern material and syntype conspecific.
