In lateral view sub-oval; ventral and dorsal faces convex; dorsal face not depressed posteriorly; inner hypostomal teeth invisible. Sides of the head with very sparse, moderately short, erect pilosity; whole head with moderately dense, very short, suberect to erect pilosity. Antennal scrobes very weakly impressed and not delimited, scrobe surface shiny, with thick, longitudinal, short, and interrupted rugae; interspaces distinctly rugo-foveolate. Occipital lobes shiny, with thick, irregular rugae, interspaces rugo-foveolate, rugae fading anteriorly; frons smooth, with few short, thick, longitudinal rugae on the anterior part; genae shiny and smooth; malar area with thin, longitudinal, moderately dense rugae, interspaces smooth or with indistinct rugulae. Centre of clypeus shiny and smooth, lateral sides with longitudinal rugulae; median notch present, moderately wide and shallow; median longitudinal carina absent; lateral longitudinal carinae indistinct. Scape, when laid back, not reaching the midlength of head; pilosity subdecumbent to erect (Fig. 18B, D View Figure 18 ). Inner hypostomal teeth distinct, small, closely spaced, triangular, with rounded apex; outer hypostomal teeth weakly developed, dentate (Fig. 85M View Figure 85 ). Mesosoma. In lateral view, promesonotum relatively low and arched, posterior mesonotum convex, without tubercle-like projections; promesonotal groove absent; metanotal groove absent; propodeal spines small, triangular, with sharp apex and wide base; humeral area laterally weakly produced (Fig. 18D View Figure 18 ). Surface shiny and smooth, sometimes with indistinct and sparse foveolae or rugulae on propodeum and promesonotum. Pilosity moderately dense, very long and suberect to erect (Fig. 18D, F View Figure 18 ). Petiole. Shiny; peduncle moderately long, finely foveolate, without horizontal lobes on its basal part; node smooth, relatively low, triangular, with rounded apex, in rear view node slightly concave; pilosity moderately dense and erect (Fig. 18D, F View Figure 18 ). Postpetiole. Shiny; in dorsal view sides with moderately short, acute, and triangular projections; pilosity long, moderately dense and erect (Fig. 18D, F View Figure 18 ). Gaster. Shiny and smooth; pilosity dense, short, and erect (Fig. 18D, F View Figure 18 ). Colour.

Etymology.
From the type locality.
Biology.
The species was collected at elevation between 70-1640 m, in dry forest on sandy soil, in Uapaca woodland, in savannah woodland, in tropical dry forest, in gallery forest, in shrubland. Nests were located in soil and under stones.
Comment.
Pheidole navoatrensis sp. nov. is most similar to P. typhlos sp. nov. Major workers. Pheidole navoatrensis sp. nov. differs from P. typhlos sp. nov. in well-developed eyes, never smooth occipital lobes, small inner hypostomal teeth and weakly developed outer hypostomal teeth, and posterior mesonotum never convex. Minor workers. Pheidole navoatrensis sp. nov. differs from P. typhlos sp. nov. in convex promesonotum, big eyes, and shallow metanotal groove.
