Description
From Wilson (2003): Closest to Pheidole cavifrons, somewhat less similar to Pheidole aberrans and Pheidole obnixa, distinguished as follows.

Major: head markedly elongate (Head Length/Head Width 1.47), and bicolored (see under color below); dorsal posterior half of head profile flat; frontal lobes in full-face view taper anteriorly into blunt acute angles; carinulae originating on frontal lobes reach well past midpoint between eyes and occiput; mesosomal convexity in side view reduced, obliquely angular; propodeal spines denticulate; promesonotum smooth and shiny.

Minor: nearly identical to minor of cavifrons (q.v.).

MEASUREMENTS (mm) Lectotype major: HW 0.72, HL 1.06, SL 0.30, EL 0.06, PW 0.50. Paralectotype minor: HW 0.50, HL 0.58, SL 0.36, EL 0.04, PW 0.32.

COLOR Major: strikingly bicolored, with anterior fourth of head dark brown, and rest of body medium yellow. Minor: concolorous light yellow.
