Description
A member of the diligens group similar in various characters to Pheidole coffeicola, Pheidole hoelldobleri, Pheidole insipida, Pheidole peregrina, Pheidole zelata, and especially Pheidole gagates, and distinguished as follows.
Major: head tricolorous (see Color below); antennal scapes thick and short, their tips touching the lateral margin of the head well short of half the distance from eye to occipital corner; propodeal spine straight, about one-third as long as the basal propodeal face; pronotum peaks at middle to form subangle; rugoreticulum present between eye and antennal fossa; carinulae on head do not extend beyond eye level more than half the Eye Length; in full-face view, concavity of occipital margin very broad.
Minor: occiput narrowed, with nuchal collar; pronotum smooth except for foveolate anterior rim; postpetiole from above bell-shaped.
MEASUREMENTS (mm) Holotype major: HW 1.06, HL 1.06, SL 0.64, EL 0.20, PW 0.56. Paratype minor: HW 0.48, HL 0.60, SL 0.70, EL 0.14, PW 0.34.
COLOR Major: head tricolorous, with clypeus yellow, head posterior to clypeus light brown, rest of head rich dark reddish brown; mesosoma and waist medium to dark reddish brown; gaster dark brown, tarsi yellow, and other appendages brownish yellow.
Minor: body medium brown; tarsi yellow; other appendages light brown.
