Description

From Wilson (2003): A small, yellow, nearly hairless member of the diligens group, similar to Pheidole bruesi, Pheidole diligens, Pheidole inversa, Pheidole radoszkowskii and [[Pheidole triconstricta]], differing by the following combination of traits.

Major: sculpture of dorsal surface of head entirely limited to longitudinal carinula restricted to part of head anterior to the posterior eye margin, with no rugoreticulum, and the frontal lobes bare; promesonotal profile strictly 2-lobed, with the lobes connected by a shallow, saddle-like concavity in dorsal-oblique view; propodeal spine very thin, needle-like; color pale yellow.

Minor: differing from that of the species just listed by its narrow occiput.

MEASUREMENTS (mm) Lectotype major: HW 0.96, HL 0.98, SL 0.66, EL 0.14, PW 0.48. Paralectotype minor: HW 0.48, HL 0.56, SL 0.66, EL 0.10, PW 0.34.

COLOR Major and minor: concolorous pale yellow.
