Description
From Wilson (2003): A large, completely foveolate and opaque member of the fallax group, somewhat similar to Pheidole aequiseta and Pheidole gouldi.
Major: antennal scape just attains occipital corner; pilosity of head and mesosoma short, erect to suberect, and mostly of same length; propodeal spines long and relatively thin; rugoreticulum forms a band from eye to eye, anterior to near anterior border of head, and onto frontal lobes; center of pronotal dorsum with broken, scattered rugulae; humerus prominent, subangular; postpetiole from above elliptical.
Minor: body completely foveolate; propodeal spines one-third as long as the basal propodeal face anterior to them, and thin; occiput narrow and with nuchal collar.
MEASUREMENTS (mm) Major (Michoacán, Mexico): HW 1.72, HL 1.82, SL 1.44, EL 0.30, PW 0.88. Syntype minor: HW 0.86, HL 1.06, SL 1.40, EL 0.22, PW 0.62.
COLOR Major: head and appendages light reddish brown, rest of body medium reddish brown.
Minor: concolorous medium dull brown except for anterior rim of head capsule and mandibles, which are yellowish brown.
Figure. Upper: major, with minor compared with syntype minor (San Jose Purua, Michoacán, Mexico, col. R. J. Hamton). Lower: syntype, minor. Scale bars = 1 mm.
Type Material
Cuernavaca, Morelos, Mexico, col. W. M. Wheeler. Musee d'Histoire Naturelle Genève and Museum of Comparative Zoology - as reported in Wilson (2003)
