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.
