Pheidole megacephala subspecies melancholica (Santschi) HNS
Six soldiers, five workers, and seven females, mostly winged, taken at Garamba (Lang and Chapin) from the stomachs of a toad (Bufo regularis) and two frogs (Rana ornatissima and Kassina senegalensis). The female is a little larger than the female of the typical megacephala HNS, with the head and thorax more sharply sculptured and the color of the body, including the clypeus and mandibles, darker, almost black; the legs more yellowish, as in the worker.
This is the host of the singular workerless parasitic ant, Anergatides kohli HNS, recently described and figured by Wasmann from the vicinity of Stanleyville.2
