Similar in various traits to Pheidole nitella, Pheidole christopherseni, Pheidole nigricula, Pheidole olsoni, Pheidole protensa, Pheidole pygmaea and Pheidole sagittaria but differing as follows.

Major: yellow; head elongate as shown; eyes set far forward, so that their distance from anterior margin of head is only an Eye Length; propodeal spines absent, replaced by obtuse angle (side view) or rounded juncture (dorsal-oblique view); carinulae extend only slightly behind eye level of head, including frontal lobes, and rest of body entirely smooth and shiny.

Minor: eye large, tapered anteriorly, and set far forward on head; propodeal spines reduced to denticles; carinulae on head extend only back to anterior margin of eyes, and all the rest of head and body smooth and shiny; occiput broad, its margin flat. Differs from the closely similar nigella in size, head shape, cephalic sculpture, eye shape, and minor scape length.
