Description

From Wilson (2003): DIAGNOSIS Similar to Pheidole bellatrix, Pheidole bison and Pheidole napoensis, differing from them and other tristis-group members as follows.

Minor: semicircular carinulae cover promesonotum except for center, which is rugoreticulate.

MEASUREMENTS (mm) Lectotype major: HW 1.30, HL 1.54, SL 0.62, EL 0.16, PW 0.82. Paralectotype minor: HW 0.52, HL 0.56, SL 0.40, EL 0.08, PW 0.32.
