Description
A member of the flavens group, most similar to Pheidole goeldii, Pheidole mittermeieri, Pheidole nuculiceps, Pheidole sculptior and Pheidole striaticeps. Distinguished by the following combination of traits.
Major: head with mandibles in full-face view almost perfectly heart-shaped; antennal scrobes present; vertex near occiput conspicuously depressed; entire dorsal surface of head, except for frontal triangle, mid-clypeus, and antennal scrobes, longitudinally carinulate; carinulae originating on frontal lobes curve weakly inward as they approach occiput, and carinulae laterad to the antennal scrobes curve strongly inward to meet those originating on the frontal lobes; all of mesosoma foveolate and opaque; postpetiole diamond-shaped.
Minor: all of head and mesosoma foveolate and opaque; eye set forward on head, separated from genal border by a distance about equal to Eye Length; carinulae on head fail to reach eye level.
MEASUREMENTS (mm) Holotype major: HW 0.72, HL 0.72, SL 0.36, EL 0.08, PW 0.34. Paratype minor: HW 0.38, HL 0.42, SL 032, EL 0.06, PW 0.24.
COLOR Major: mesosoma, waist, and anterior strip of first gastral tergite yellowish brown; head and rest of gaster medium brown; appendages medium yellow.
Minor: concolorous dark yellow.
Both castes are sometimes much darker in shade.
