Description

DIAGNOSIS Similar in various traits to Pheidole albipes, Pheidole ceibana, Pheidole lemnisca, Pheidole peltastes, Pheidole renae, Pheidole tayrona and Pheidole xyston, differing as follows.

Major: blackish brown body contrasts with pale yellow legs; shallow antennal scrobe present; on dorsal head surface, carinulae and rugulae covering anterior three-fourths of head give way to band of irregular rugoreticulum just in advance of occiput, which gives way in turn to the smooth occiput; eye narrow, placed far forward on head; humeri and metanotum rugoreticulate; postpetiole elliptical.

Minor: eye very large, set forward on the head so that it is separated from the anterior head margin by only about a Head Length; humerus denticulate; propodeal spine equilaterally triangular.

MEASUREMENTS (mm) Holotype major: HW 0.76, HL 0.80, SL 0.48, EL 0.08, PW 0.42. Paratype minor: HW 0.40, HL 0.44, SL 0.42, EL 0.08, PW 0.22.

COLOR Major: body blackish brown except for genae, which are contrasting reddish yellow; mandibles reddish brown; other appendages pale yellow.

Minor: body blackish brown, appendages pale yellow.
