Text Figure 21

Akenge, [[worker]]; Medje, [[worker]]; Ngayu, [[worker]]; Niangara, [[worker]]; Niapu, [[worker]]. Eightysix specimens, all taken from the stomachs of four species of toads (Bufo polycercus, superciliaris, funereus, and tuberosus) collected by Lang and Chapin.

Stitz has described an 0. intermedius which differs from the typical assiniensis   HNS only in having the striae on the pronotum of the worker more arcuately concentric and therefore more as in O. haematoda   HNS and not simply transverse. A study of the long series of specimens before me shows that there is great variation in the pronotal striation, many specimens agreeing with Stitz's description; others having the striae in an asymmetrical whorl like that exhibited by the ridges on the tips of the fingers, and in a considerable number the striae are simply transverse, as described by Emery for the typical assiniensis   HNS . I do not regard these differences as more than nest variations and have therefore relegated Stitz's intermedius, which Santschi is willing to regard as a subspecies of assiniensis   HNS , to the synonymy.
