Description
A small, yellow species whose major has an elongated head, the dorsal surface of which, with the exception of the mid-clypeus and frontal triangle, is completely foveolate and opaque; the rest of the cephalic sculpturing comprising longitudinal carinulae confined to the anterior half of the capsule; antennal scrobe absent; thick long, vertical propodeal spines are present, thin tips turning slightly forward in side view; small, subangulate mesonotal convexity present, and postpetiolar node conulate.
Similar to Pheidole charazana, Pheidole longinoi, Pheidole neolongiceps and Pheidole prolixa, but differing from each in various combinations of the above traits, and other traits, as illustrated.
