Description
Somewhat similar in various traits to the Nearctic species Pheidole casta, Pheidole mera and Pheidole tysoni, and easily distinguished as follows.
Major: posterior half of dorsal head profile flat; eye set well forward on head, pearl-shaped, with anterior end tapered slightly; head bicolored; dorsum of promesonotum covered with faint longitudinal carinulae, and foveolate; petiolar node tapered at apex; postpetiole from above diamond-shaped.
Minor: eye set well forward on head; occiput broad, its margin weakly concave; all of head, mesosoma, and petiole foveolate.
MEASUREMENTS (mm) Holotype major: HW 0.70, HL 0.78, SL 0.34, EL 0.10, PW 0.36. Paratype minor: HW 0.40, HL 0.44, SL 0.32, EL 0.06, PW 0.26.
COLOR Major: most of body medium brown (mesosoma tending to dark brown), and anterior one-sixth of head capsule, and appendages, brownish yellow.
Minor: body medium brown, appendages brownish yellow.
