Description
A member of the fallax group similar in various traits to Pheidole chiapasana, Pheidole dentata, Pheidole humeridens, Pheidole industa, Pheidole laevivertex, Pheidole maja and Pheidole tetroides, distinguished as follows.
Major: propodeal spines equilaterally triangular in side view; rugoreticulum of head a band from eye to antennal fossa; carinulae on head extend more than halfway from level of eyes to level of occiput; occipital margin in full-face view strongly convex; dorsal pronotal profile in dorsal-oblique view faintly bilobous; postpetiole from above elliptical, with angulate lateral borders; anterior and lateral pronotal margins carinulate.
Minor: a rugula stretches across the anterior rim of the middle clypeal segment; propodeal spines equilaterally triangular in side view; pronotum smoothly convex in dorsal-oblique view; occiput shallowly convex.
MEASUREMENTS (mm) Holotype major: HW 1.24, HL 1.36, SL 0.84, EL 0.20, PW 0.66. Paratype minor: HW 0.64, HL 0.74, SL 0.84, EL 0.18, PW 0.44.
COLOR Major: body light reddish brown, appendages dark yellow.
Minor: body rich dark reddish brown, antennae plain medium brown, other appendages reddish yellow.
