The soldier of G. (C.) holivianus Snyder is distinctive due to the 

 small size of the marginal teeth or denticles on the mandibles; the 

 marginal teeth and the emargination or entirety of the anterior 

 margin of the pronotum are excellent specific characters in the 

 soldier caste of Gornitermes. G. holivianus has the head tapering 

 anteriorly, an upturned, slender frontal tube, head with dense long 

 hairs, has 15 segments to the antenna, and has the anterior margin 

 of the pronotum emarginate, hence differing from G. (G.) lespesi 

 Fritz Miiller.
