Taxonomic Notes

Taylor et al. (2018) - It is quite clear from the original Emery description and the type image, CASENT0904210, that true Pheidole caffra does not have strongly marked sculpturation on the occiput and the frontal carinae reach the posterior quarter of the head; the colour also is given as ferruginous, dull with the gaster piceous and shiny.

They then propose treating this taxon as a full species, a treatment not followed by later authors.
