Tetramorium species groups

T. plesiarum and several undescribed species do not fit well within the T. ranarum group. Tetramorium plesiarum and allies all possess a distinct and sharply defined antennal scrobe, whereas the scrobe is at most shallowly developed in all other T. ranarum group members. This character seems to be of high diagnostic importance since it is absent in all other Malagasy species groups. For this reason, we consider T. plesiarum and allies to belong to a group distinct from the T. ranarum group.
