Key to Polyrhachis vestita-group species

Notes

Sulawesi has several endemic Myrma species that constitute the vestita species-group characterised by a scale-like petiole that lacks spines and has a dorsal margin with only blunt teeth or a shallow median emargination. This petiolar configuration resembles that of Polyrhachis abrupta from Halmahera, but this species differs from those of the vestita-group in having strongly truncate eyes and a distinct carina running from the eyes towards the occipital corners. A petiole lacking dorsal spines is also characteristic of the inermis-group, but its constituent species differ from those of the vestita-group in having their dorsal petiolar margin smooth and entire. In addition, members of the vestita-group are some of the largest species of Myrma, while the inermis-group includes some of the smallest.
