Taxonomic Notes
Taylor et al. (2018) note that Benin specimens are similar to the West African forms of Emery (1915), a major worker from Cameroun, CASENT0173311, and a minor worker, CASENT0173310, are listed on Antweb as “Pheidole punctulata” but they differ from the types of that species from South Africa (major, CASENT0901316, minor, CASENT0901315).
They then propose treating P. impressifronts as a full species. This as not been accepted by later authors.
