Description

From Wilson (2003): DIAGNOSIS Similar to Pheidole amata, Pheidole ambigua, Pheidole celaena, Pheidole fera, Pheidole germaini, Pheidole peruviana, Pheidole rutilana, Pheidole superba and Pheidole vomer, differing as follows.

Major: large, rich reddish brown; center of median clypeal carinae projects forward as a short lobe; head subrectangular, elongate, with deep occipital cleft; posterior half of dorsal head surface smooth and shiny, anterior half carinulate; no rugoreticulum; small metanotal convexity present in addition to mesonotal convexity; propodeal spines in side view large and vertical to propodeal basal face; apex of petiolar node in side view tapers to a blunt point; mesosoma and waist foveolate and opaque.

Minor: occiput narrow, with nuchal collar; all of body foveolate and opaque except gaster, which is entirely smooth; propodeal spines reduced to denticles.

MEASUREMENTS (mm) Lectotype major: HW 2.02, HL 2.50, SL 1.00, EL 0.24, PW 0.80. Paralectotype minor: HW 0.64, HL 0.72, SL 0.84, EL 0.12, PW 0.42.

COLOR Major: head, mandibles, and mesosoma rich medium reddish brown; waist and gaster plain medium to dark brown; appendages yellowish brown.

Minor: head and gaster medium brown; mesosoma, waist, and appendages light brown.

Figure. Upper: lectotype, major (with magnified profile of metanotum and surrounding area shown above side view; and below head, three hypostomas, the lectotype on the left and two examples from an Anápolis, Goiás, series in the middle and on right). Lower: paralectotype, minor. Scale bars = 1 mm.
