Description
DIAGNOSIS A large, yellow member of the tristis group, similar to Pheidole rotundiceps, Pheidole sphaerica and Pheidole subsphaerica, easily distinguished by the following traits.
Major: head greatly swollen; clypeus and mandibles reduced proportionate to the head; outline of head in full-face view almost completely devoid of pilosity; in side view, profiles of both anterior dorsal half and anterior ventral half of head capsule densely pilose, but profiles of posterior dorsal and ventral halves bare of pilosity; propodeal spines long and acute.
Minor: body slender; occiput narrowed, with nuchal collar; propodeal spines long and slender, i.e., needle-like.
MEASUREMENTS (mm) Holotype major: HW 1.78, HL 1.66, SL 1.02, EL 0.22, PW 0.84. Paratype minor: HW 0.64, HL 0.80, SL 1.06, EL 0.16, PW 0.44.
COLOR Major: head and appendages medium yellow; mesosoma, waist, and gaster yellowish brown.
Minor: concolorous dark yellow.
Figure. Upper: holotype, major. Lower: paratype, minor. Scale bars = 1 mm.
