Description

DIAGNOSIS From Wilson (2003): Similar in various traits to Pheidole aper, Pheidole bambusarum, Pheidole brevicona, Pheidole dyctiota, Pheidole laeviventris, Pheidole risii, Pheidole rugatula, Pheidole senilis, Pheidole sigillata, Pheidole trachyderma and Pheidole traini, differing as follows.

Major: head from the side and in full-face view subrectangular, elongate (Head Length 1.2X Head Width), expanded slightly anterior to eyes so that in full-face view the anterior margin is wider than the occiput; all of dorsal head surface, including frontal lobes rugoreticulate (except for antennal fossae, which are rugulose, and frontal triangle and mid-clypeus, which are smooth); all of promesothorax rugoreticulate; propodeal spines thin, one-third as long as propodeal basal face; postpetiole from above diamond-shaped.

Minor: most of dorsal head surface and all of promesothorax rugoreticulate; occiput strongly narrowed but with no nuchal collar; in side view propodeum descends to metanotum in vertical face.

MEASUREMENTS (mm) Lectotype major: HW 1.26, HL 1.54, SL 0.80,. EL 0.20, PW 0.74. Paralectotype minor: HW 0.70, HL 0.84, SL 0.84, EL 0.12, PW 0.48.

COLOR Major: head, mesosoma, and antennae medium reddish brown; waist, gaster, and legs light reddish brown.

Minor: concolorous light reddish brown.
