Imaging technique: 

The posterolateral lobes distinctly rugose and the lack of a punctate ground sculpture gives the head a shiny appearance. Used in Antkey to separate the major workers of Pheidole fervens, Pheidole flavens, Pheidole moerens, Pheidole obscurior and Pheidole teneriffana from those of all other Pheidole species.
