Description
From Wilson (2003): DIAGNOSIS A large, robust member of the tristis group with quadrate head shape in full-face view, similar to Pheidole fabricator, Pheidole gaigei, Pheidole godmani, Pheidole grantae (=Pheidole exarata), Pheidole nigella and Pheidole tristis, and distinguished by the following combination of traits.
Major: head quadrate, with shallow median occipital cleft in full-face view; hind femora swollen in middle; frontal lobe extended as short angular protrusion in side view; humerus in dorsal-oblique view very prominent, and right-subtriangular in outline; postpetiole bell-shaped from above; all of pronotal dorsum transversely carinulate.
Minor: humerus prominent, subangulate; carinulae originating from frontal carinae curve laterally toward sides of head; pronotal dorsum transversely carinulate.
MEASUREMENTS (mm) Holotype major: HW 1.58, HL 1.66, SL 0.84, EL 0.20, PW 0.80. Paratype minor: HW 0.72, HL 0.72, SL 0.72, EL 0.12, PW 0.48.
COLOR Major: body and mandibles dark reddish brown, appendages medium brownish yellow.
Minor: body plain medium brown, appendages plain light brown.
Figure. Upper: holotype, major; the leg part shown is the right hind femur . Lower: minor, tentatively associated with holotype by Carlos Emery (Bolivia). Scale bars = 1 mm.
Type Material
