Description

DIAGNOSIS Closely similar to Pheidole subarmata, but differing by the following traits.

Major: larger and more darkly colored; pronotum bilobous; propodeal spines longer and thinner, postpetiolar nodal margins more sharply angulate; carinulae mesad to the eyes extend halfway to the occipital border.

Minor: larger and darker, otherwise nearly identical to Pheidole subarmata. See also the less similar Pheidole allarmata, Pheidole cramptoni, Pheidole synarmata and Pheidole triplex.

MEASUREMENTS (mm) Holotype major: HW 1.20, HL 1.40, SL 0.60, EL 0.16, PW 0.64. Paratype minor: HW 0.52, HL 0.54, SL 0.54, EL 0.10, PW 0.34.

COLOR Major: head and body dark brown, appendages light to medium brown.

Minor: head and body medium brown, appendages light brown.

Figure. Upper: holotype, major. Lower: paratype, minor. Scale bars = 1 mm.
