Head punctate (minor, minor)

Head, including the area mesad of the frontal carinae, entirely covered by reticulated network of punctures, giving it a dull appearance; if rugae are present they are generally short segments and mostly restricted to posterior portion of head (minor worker). Character used to separate P. anastasii, P. bilimeki, P. flavens, P. navigans and P. parva from all other introduced Pheidole.
