DIAGNOSIS Similar in various traits to Pheidole amazonica, Pheidole nitidicollis, Pheidole moffetti and Pheidole pariana, differing as follows.

Major: brown, with bicolored head; pilosity dense, with many hairs 1.5–2.0X Eye Length; in dorsal-oblique view, humerus high, descends in continuous nearly flat curve to metanotum; propodeal spines half as long as propodeal basal face preceding them; from above, postpetiolar node oval and very narrow, only about as wide as petiolar node; dorsal surface of head carinulate except for occiput, frontal triangle, and mid-clypeus; occiput smooth with scattered foveae.

Minor: pilosity very long, some hairs 2X Eye Length; humerus in dorsal-oblique view angulate; propodeal spines moderately long, and thin; occiput narrowed somewhat, its margin concave, lacking nuchal collar.

MEASUREMENTS (mm) Holotype major: HW 0.86, HL 0.90, SL 0.46, EL 0.14, PW 0.44. Paratype minor: HW 0.46, HL 0.50, SL 0.44, EL 0.10, PW 0.32.

COLOR Major: rear two-thirds of head, as well as frontal triangle, part of vertex, and midclypeus, dark brown and rest of head dark yellow, as depicted; waist light brown.

Minor: body dark brown; mandibles, funiculi, and tarsi medium yellow, remainder of appendages brownish yellow.
