Pheidole centeotl

From Wilson (2003): Mann (in Wheeler 1914c) found numerous colonies of this species nesting under stones on a hillside in oak-pine woodland near Molino Guerrero (an ore mill), on the eastern slope of the mountain range east of Pachuca. A colony collected by Robert J. Hamton near Jalapa, Veracruz, was nesting beneath a stone in pine forest at 2350 m. Winged reproductives were in a nest at 2200 m near Cuernavaca on 26 May 1986 (W. P. MacKay).

Distribution
I have seen series of centeotl from the following central and southeastern states of Mexico: Hidalgo, Michoacán, Morelos, Puebla, and Veracruz, all collected at elevations of 2200–2400 m. (Wilson 2003)

This taxon was described from Mexico.

Description
From Wilson (2003): A member of the pilifera group with 3 worker castes (major, supermajor, minor) similar to Pheidole macclendoni of Arizona and Texas, differing as follows.

Major: propodeal spines much shorter; humerus in dorsal-oblique view less prominent; postpetiolar node seen from above subangulate and diamond-shaped; light reddish brown, not yellow.

Supermajor: occipital cleft deeper, its sides rising more steeply to the occipital lobes on either side.

Minor: propodeal spine well-developed; carinulae present on frontal lobes, and those mesad to the eye extend posteriorly beyond the eye by as much as an Eye Length.

MEASUREMENTS (mm) Lectotype major: HW 1.10, HL 1.20, SL 0.62, EL 0.14, PW 0.56. Paralectotype supermajor: HW 1.84, HL 2.06, SL 0.80, EL 0.22, PW 0.80. Paralectotype minor: HW 0.60, HL 0.66, SL 0.56, EL 0.12, PW 0.38.

COLOR Major: body light to medium reddish brown, appendages light reddish brown.

Supermajor: light to medium reddish brown.

Minor: concolorous light reddish brown.
