Eguchi (2001) – P. magrettii is doubtless closely related to Pheidole nodgii and Pheidole tjibodana. The differences between the examined specimens of P. magrettii and the type series of the two “forms” of P. nodgii are as follows: lateral surface of occipital lobe of the major largely smooth and shining in the former, while reticulate, with enclosures punctured and dull in the latter; propodeal spine 2.5 times as long as the diameter of propodeal spiracle in the major and 1.5 times in the minor in the former, while more than 3.5 times in both the subcastes in the latter.
