Identification
This species is similar to Temnothorax xia (Fig. 35), but differs in having head dorsum loosely longitudinally rugose centrally, mesonotal dorsum smooth, and body color almost black; in T. xia head dorsum densely longitudinally rugose centrally, mesonotal dorsum coarsely reticulate and body color reddish brown, gaster black.
It is also similar to Temnothorax lixia (Fig. 28), but differs in having head dorsum loosely longitudinally rugose, pronotal sides coarsely longitudinally rugose, propodeal spines longer than their basal width in lateral view, petiolar node symmetrical, anterodorsal corner as high as posterodorsal corner in lateral view, petiolar node weakly punctate; in T. lixia head dorsum densely longitudinally rugose, pronotal sides coarsely reticulate, propodeal spines as long as their basal width in lateral view, petiolar node asymmetrical, anterodorsal corner higher than posterodorsal corner in lateral view, petiolar node finely reticulate.
