Description
From Wilson (2003): DIAGNOSIS A member of the tristis group, similar to Pheidole balzani, Pheidole godmani, Pheidole grandinodus, Pheidole huilana, Pheidole obrima, and, less so, to species listed with them, distinguished as follows.
Major: postpetiole from above bell-shaped, 2X broader than petiole; postpetiole with prominent ventral, forward-projecting subangular process; anterior third of pronotal dorsum and all of mesopleuron carinulate; carinulae on dorsal surface of head reach midway between eye and occipital border.
Minor: occiput very broad, lacking nuchal collar; propodeal spines reduced to denticles; margins all around of pronotal dorsum, as well as lower half of mesopleuron, carinulate.
MEASUREMENTS (mm) Syntype major: HW 1.28, HL 1.38, SL 0.72, EL 0.08, PW 0.62. Syntype minor: HW 0.64, HL 0.72, SL 0.66, EL 0.12, PW 0.44.
COLOR Major: concolorous light reddish yellow.
Minor: concolorous brownish yellow.
