DIAGNOSIS Similar to Pheidole allarmata, Pheidole cramptoni, Pheidole hasticeps, Pheidole subarmata and Pheidole triplex, differing from these and other Pheidole by the following combination of traits.

Major: head elongate; in side view, frontal lobe extending vertically off the dorsal surface of the head as a spine-like projection; promesonotum forming a large, bulbous, smoothly semicircular outline; petiolar spine well-developed and vertical; posterior half of the head capsule and almost all of the body smooth and shiny.

Minor: occiput broad and concave, lacking nuchal collar; promesonotal profile forming a prominent, smooth semicircle; except for the foveolate mesopleuron and lower side of the petiole, the body is completely smooth and shiny.

MEASUREMENTS (mm) Holotype major: HW 0.92, HL 1.14, SL 0.42, EL 0.12, PW 0.46. Paratype minor: HW 0.46, HL 0.50, SL 0.42, EL 0.06, PW 0.30.

COLOR Major: concolorous clear medium yellow.
