Described from three soldiers and several workers from a small 

 colony found beneath a stone It is evidently much rarer than the 

 preceding species, to which it is related, but readily distinguished, 



in the soldier phase, by the characters noted in the key to the species. 

 The worker of colaensis has the head shorter and very narrowly 

 concave behind, with the margin rounded. The occiput is sparsely 

 punctate, the thorax is not striate and the lamellate process of the 

 mesonotum is thicker and not strongly impressed before the tip.
