Description
From Wilson (2003): A member of the aberrans group closest to Pheidole fracticeps, differing from it and other species of the group by the following combination of traits.
Major: very small; brownish yellow with brown spot on vertex; hypostoma 4-toothed; in side view, occiput projects out like a brow, its apex rounded and the profile of the head below it dipping away as a strong convexity; in full-face view, occiput bearing several widely spaced carinulae that travel from the dorsal midline obliquely toward the occipital corners; eye oval, placed forward to its anterior border is only a little more than an Eye Length from the anterior genal border.
Minor: almost all of head, mesosoma, and waist foveolate; most of dorsal surface of head carinulate, with a rugoreticulum mesad to each eye.
MEASUREMENTS (mm) Lectotype major: HW 0.64, HL 0.84, SL 0.30, EL 0.12, PW 0.40. Paralectotype minor: HW 0.40, HL 0.44, SL 0.32, EL 0.06, PW 0.24.
COLOR Major: overall brownish yellow, with a light brown spot on the vertex.
Minor: overall brownish yellow except for posterior half of dorsum of head, which is medium brown.
