Salata and Fisher (2020) - A member of the Pheidole makaensis species group. Major. Head in full-face view elongated; sides of the head with moderately dense, very long, erect pilosity; occipital lobes with thick, sparse, short, irregular, and slightly arcuate rugae, interspaces smooth; inner hypostomal teeth distinct, moderately high, closely spaced, triangular, with rounded apex and wide base; outer hypostomal teeth bigger and wider than inner hypostomal teeth, lobe-like; inner and outer teeth closely spaced and connected by moderately deep concavity. Minor:. Head foveolate, genae smooth; scape, when laid back, surpassing the posterior head margin by two-fifths of its length; promesonotum low, convex, short, with posterior declivity smoothly declining towards propodeum; mesosoma foveolate, anepisternum, katepisternum and mesonotum with fading sculpture; propodeal spines small, triangular.
Pheidole makaensis is most similar to Pheidole avaratra. Major workers. It differs from P. avaratra in very sparse and interrupted rugae on frons and frons with mostly smooth interspaces; smooth genae, lobe-like outer hypostomal teeth which are distinctly bigger than inner hypostomal teeth, and katepisternum with smooth notch. Minor workers. It differs from P. avaratra in denser and longer pilosity on head, mesosoma, and gaster.

Sides of the head with moderately dense, very long, erect pilosity; whole head with moderately dense, long, suberect to erect pilosity. Antennal scrobes indistinct and not delimited by carinulae; scrobe surface shiny, with thick, sparse, longitudinal rugae; interspaces smooth and finely foveolate on the posterior part. Occipital lobes shiny, with thick, sparse, short, irregular, and slightly arcuate rugae, interspaces smooth; frons with moderately sparse, thick, longitudinal, interrupted rugae, interspaces smooth and indistinctly rugulae on the posterior part; genae shiny and smooth; malar area with thick, sparse, longitudinal rugae, interspaces smooth. Centre of clypeus shiny and smooth, lateral sides with longitudinal rugae; median notch present, narrow, and moderately deep; median longitudinal carina absent; lateral longitudinal carinae absent. Scape, when laid back, not reaching the midlength of head; pilosity erect. Inner hypostomal teeth distinct, moderately high, closely spaced, triangular, with rounded apex and wide base; outer hypostomal teeth bigger and wider than inner hypostomal teeth, lobe-like; inner and outer teeth closely spaced and connected by moderately deep concavity. Mesosoma. In lateral view, promesonotum relatively low and arched, dorsal mesonotum slightly concave, posterior mesonotum steep, with tubercle-like projections; promesonotal groove absent; metanotal groove absent; propodeal spines short, triangular, with sharp apex and relatively wide base; humeral area laterally weakly produced.
