Salata and Fisher (2020) - A member of the Pheidole ferruginea complex in the Pheidole ferruginea species group. Head in full-face view cordate, widened posteriorly; sides of the head with moderately dense, short, suberect to erect pilosity; antennal scrobes present, weakly impressed, and indistinctly delimited ventrally and posteriorly by carinulae; scrobe surface foveolate, with indistinct, thick, moderately sparse, irregular rugae; propodeal spines long (PSL: 0.2-0.26 (0.24)); gaster shagreened; inner hypostomal teeth distinct, high, narrow, and triangular, closely spaced, with rounded apex; outer hypostomal teeth approximately as high as inner hypostomal teeth, but thinner and with wider base, lobe-like. Minor:. Head and mesosoma foveolate; propodeal spines long (PSL: 0.14-0.17 (0.15)); promesonotum low, convex, short, with posterior declivity smoothly declining towards propodeum.
Pheidole manantenensis is most similar to Pheidole vohemarensis. Majors workers. It differs from P. vohemarensis in presence of irregular rugae on antennal scrobes, frons with foveolae, lower promesonotum, and petiolar peduncle with short horizontal lobes on its basal part. Minor workers. It differs from P. vohemarensis in promesonotum with posterior declivity smoothly declining towards propodeum, and foveolate katepisternum and mesonotum.

Sides of the head with moderately dense, short, suberect to erect pilosity; whole head with moderately dense, long, suberect to erect pilosity. Antennal scrobes impressed and delimited ventrally and posteriorly by carinulae; scrobe surface foveolate, with indistinct, thick, moderately sparse, irregular rugae. Occipital lobes shiny, foveolate, with additional thick, sparse, irregular rugae, rugae weakening posteriorly; frons with moderately sparse, thick, longitudinal rugae, on the posterior part rugae longitudinal to irregular, interspaces superficially foveolate; genae foveolate, with additional, indistinct, and irregular rugulae; malar area with thick, sparse, longitudinal rugae, interspaces smooth to indistinctly rugulose. Centre of clypeus shiny and with indistinct, short rugulae, lateral sides with longitudinal rugae; median notch present, moderately wide, and shallow; median longitudinal carina present; lateral longitudinal carinae present. Scape, when laid back, slightly exceeding the midlength of head; pilosity suberect to erect. Inner hypostomal teeth distinct, high, narrow, and triangular, closely spaced, with rounded apex; outer hypostomal teeth approximately as high as inner hypostomal teeth, but thinner and with wider base, lobe-like. Mesosoma.
