Identification

Terayama (2009) - This species has an elongate head and prothorax. The species resembles Aphaenogaster takahashii by the elongate head with a remarkable neck at posterior portion. However, it is separated from the latter by the convex anterior margin of clypeus (anterior margin of clypeus with a median notch in takahashii), the large postpetiole (postpetiole as high as petiole in takahashii), and posterior directed propodeal spines (propodeal spines directed upward in takahashii).
