Description
DIAGNOSIS Similar to Pheidole pidax, Pheidole rosae, Pheidole rosula, and especially to Pheidole guayasana, differing as follows.
Major: reddish yellow; frontal lobes extended forward as conspicuous right-angular and slightly upward-turning processes, seen from the side; antennal scrobes present, each followed posteriorly by a patch of rugoreticulum; rugoreticulum absent from anterior half of head; occipital lobes in full-face view tending toward subangulate; posterior half of pronotal profile smoothly convex in dorsaloblique view; metanotum and dorsal propodeal face covered by transverse carinulae.
Minor: propodeal spines small, but well developed; entire promesonotal dorsum transversely carinulate; lateral margins of posterior half of head entirely carinulate.
MEASUREMENTS (mm) Holotype major: HW 1.58, HL 1.72, SL 0.78, EL 0.16, PW 0.80. Paratype minor: HW 0.64, HL 0.68, SL 0.80, EL 0.04, PW 0.42.
COLOR Major: body dark reddish yellow, gaster plain medium brown, appendages medium yellow.
Minor: body light brownish yellow, appendages clear medium yellow.
