Notes

The inermis species-group was introduced by Bolton (1974) and includes some of the smallest members of the subgenus. The inermis -group is characterised by well developed pronotal spines, a petiole with two short lateral spines and an entire, arcuate dorsal petiolar margin, and by closely approximated frontal carinae producing an extremely narrow central area.

There are about ten undescribed species from Borneo that are part of this group.
