Polyrhachis stricta

Polyrhachis stricta is known only from two specimens found foraging on the ground and low vegetation at the type locality.

Identification
Polyrhachis stricta somewhat resembles Polyrhachis placida as they have similar colour patterns. However, the clypeus in P. stricta is almost straight in lateral view with the basal margin only shallowly impressed, while in P. placida the profile of the clypeus is distintly sinuate and the basal margin deeper. The promesonotal lateral margins in P. stricta are strongly converging posteriorly (PMI >190) with the propodeal spines weakly upturned. In contrast, in P. placida the promesonotal margins coverge less strongly (PMI <168) and the propodeal spines curve downwards from their midlength. The pilosity in P. placida is also distintly longer and mostly silvery with the pubescence somewhat less tidy, notably over the gastral dorsum.
