Nomenclature

 *  granulata. Pheidole (Ceratopheidole) granulata Pergande, 1896: 890 (s.) MEXICO. Combination in Ceratopheidole: Emery, 1922e: 113; in Pheidole: Kempf, 1972a: 183. See also: Wilson, 2003: 542.

Description
From Wilson (2003): DIAGNOSIS A member of the small granulata group, characterized by a 4-segmented antennal club, and distinguished within it as follows.

Major: entire body including all the gastral segments, foveolate and opaque; antennal scape very long, exceeding occipital comer; head subrectangular, with a deeply concave occipital border in full-face view; rugoreticulum present between each eye and antennal fossa; postpetiole from above bell-shaped.

Minor: occiput tapered into a neck with a nuchal collar; scape very long, its tip exceeding the occipital comer in full-face view by half its own length.

Overall, the habitus of this species is typical for a member of the fallax group, except for the 4-segmented club.

MEASUREMENTS (mm) Major (Burrera, Baja California Sur): HW 1.48, HL 1.74, SL 1.58, EL 0.26, PW 0.72. Minor (Burrera): HW 0.60, HL 0.92, SL 1.32, EL 0.20, PW 0.44.

COLOR Major: brownish yellow, with gaster a shade darker.

Minor: concolorous medium yellow.
