DIAGNOSIS A medium-sized light brown (major) to yellow (minor) species distinguished in the major by curved, subrecumbent hairs (hence “woolly” hairs) all along the mesosomal dorsum; longitudinal carinulae covering all of the head except the occiput, mid-clypeus, and frontal triangle; lack of rugoreticulum anywhere; and broadly oval postpetiolar node.
Similar to Pheidole delicata, but delicata has longer pilosity, none of which is “woolly,” shorter propodeal spines, narrow petiolar node apex, and other details in body form, sculpturing, and pilosity as shown.
MEASUREMENTS (mm) Major: HW 0.98, HL 0.96, SL 0.58, EL 0.12, PW 0.46. Minor: HW 0.50, HL 0.54, SL 0.54, EL 0.10, PW 0.30.
COLOR Major: gaster light brown; rest of body, as well as appendages, medium to dark yellow.
Minor: gaster brownish yellow, rest of body medium yellow, appendages light yellow.
Figure. Upper: holotype, major. Lower: paratype, minor. Scale bars = 1 mm.
