Taxonomic Notes
Taylor et al. (2018) note that all available samples and the type major are dark brown contrasting with the yellow brown Pheidole megacephala rotundata (listed as a full species, without comment or justification). They therefore propose treating this taxon as a full species. This treatment has not been followed by later authors.
