DIAGNOSIS A very small, yellow member of the flavens group, distinguished in the major by an elongated head entirely covered dorsally with longitudinal carinulae, which grow faint and curve inwardly in the posterior third of the head to converge toward and meet at the midline, becoming horizontal near the occiput.

Major: also with broken transverse carinulae on pronotal dorsum; a small but distinct mesonotal convexity; propodeal spines reduced to denticles; and a large propodeal spiracle.

Minor: all of head and mesosoma foveolate and opaque; propodeal spines reduced to denticles.

Similar to Pheidole browni, Pheidole casta, Pheidole mera, Pheidole olsoni and Pheidole prolixa, but easily distinguished by the above traits.

MEASUREMENTS (mm) Holotype major: HW 0.60, HL 0.82, SL 0.34, EL 0.10, PW 0.32. Paratype minor: HW 0.38, HL 0.44, SL 0.34, EL 0.06, PW 0.36.

COLOR Major and minor concolorous medium yellow.
