Imperial Carpenter Ants
Diagnosis: Emery (1925): "Workers - At present, only minors are known; to judge by the head of the female, caste polymorphism appears to be weak or insignificant. Head broadest anteriorly, at mandibular insertions, and rounded posterior to the ogive (missile) shaped eyes; postocciput (articulatory joint of head with pronotum) exposed as occipital ridge reduced to absence. Clypeus lacking median carina, and anteriorly forming a very short, rounded lobe. Frontal carinae close-set; antennal insertions set remarkably distant from posterior clypeal margin. Mandibles with lateral margins nearly straight but curving apically; masticatory margin very oblique, armed with strong teeth, particularly the apical tooth which is very long and acute. Palps very long and hairy. Mesosoma slender; dorsum continuously arched. Petiolar node thick, subpyramidal. Limbs very long. Female. - Head narrowing posteriorly behind eyes, posterior margin truncate. Clypeus subcarinate. Mandibles and palpi as in the worker. Male. - Unknown.
Geographical distribution of the species. - This subgenus is based on the species C. caesar, Forel, which has been found in various places in western and eastern tropical Africa."
