Description
DIAGNOSIS Similar in various traits to Pheidole angulifera, Pheidole dimidiata, Pheidole erratilis, Pheidole gilva, Pheidole schmalzi and Pheidole tambopatae, differing as follows.
Major: head bicolored as illustrated; median ocellus present; humerus in dorsal-oblique view bearing a right-angular extension; occipital cleft very broad and moderately deep; propodeal spines directed strongly backward; postpetiole very narrow and oval from above; rear quarter of dorsal head surface smooth and shiny.
Minor: occiput somewhat narrowed, its margin weakly convex, and lacking nuchal collar; propodeal spines directed strongly backward; head almost completely smooth and shiny, with only a few faint carinulae at the antennal fossae; pilosity long, some hairs longer than Eye Length.
MEASUREMENTS (mm) Holotype major: HW 0.74, HL 0.80, SL 0.42, EL 0.10, PW 0.36. Paratype minor: HW 0.42, HL 0.46, SL 0.40, EL 0.12, PW 0.30.
COLOR Major: head bicolored, with vertex and frontal triangle medium brown and rest of head brownish yellow; tarsi brownish yellow; rest of body and appendages light brown.
Minor: head and gaster dark brown, tarsi brownish yellow, rest of body and appendages medium brown.
