Mesosoma. In lateral view, promesonotum short, angular, and high, with slightly convex posterior declivity; promesonotal groove absent; metanotal groove absent; propodeal spines very long, massive basally, with acute apex; humeral area laterally weakly produced (Fig. 33D View Figure 33 ). Surface shiny, with fine, dense rugoreticulation, sometimes sculpture weakening on dorsum. Pilosity sparse, long, and erect (Fig. 33D, F View Figure 33 ). Petiole. Shagreened; peduncle relatively long, with small tooth-like horizontal lobes on its basal part; node triangular, with rounded apex, in rear view node convex; pilosity moderately sparse and erect (Fig. 33D, F View Figure 33 ). Postpetiole. Shagreened; in dorsal view sides with acute, horn-like, moderately long projections; pilosity long, moderately sparse, and erect (Fig. 33D, F View Figure 33 ). Petiole. First gastral tergite shagreened, at least on its basal part; pilosity moderately dense, long, and erect (Fig. 33D, F View Figure 33 ). Colour.

Whole head with fine and dense rugo-punctuation, only basal area of frons and genae with sculpture reduced or sometimes absent; antennal sockets with dense carinae curved outward. Clypeus with median longitudinal carina present; two lateral longitudinal carinae absent. Scape, when laid back, surpassing posterior head margin by two-fifths of its length; pilosity suberect to erect (Fig. 33A, C View Figure 33 ). Mesosoma. In lateral view, promesonotum high, short, and convex; promesonotal groove present, indistinct; metanotal groove shallow and indistinct; propodeal spines very long, massive basally, with acute apex (Fig. 33C View Figure 33 ).

Peduncle relatively long and thin; node low, triangular; with few long, erect setae (Fig. 33C, E View Figure 33 ). Postpetiole. Short, low, and slightly convex; with few long, erect setae at the anterior edge (Fig. 33C, E View Figure 33 ). Petiole. With few long, erect setae (Fig. 33C, E View Figure 33 ). Colour. Unicolourous, bright brown to brown (Fig. 33C, E View Figure 33 ).
Etymology.
Named after Podarge, a harpy from Greek mythology, in reference to long and sharp propodeal spines of minor workers reminiscent of claws.
Biology.
The species was collected between 210-800 m in elevation, in rainforest and tropical dry forest. Nests were located in rotten logs.
Comments.
This species is most similar to P. aelloea sp. nov. and P. ocypodea sp. nov. Major workers. Pheidole podargea sp. nov. can be distinguished from P. aelloea sp. nov. and P. ocypodea sp. nov. by outer hypostomal teeth approximately the same size as the inner ones and lack of smooth sculpture on genae and propodeum. Minor workers. Pheidole podargea sp. nov. can be distinguished from P. aelloea sp. nov. and P. ocypodea sp. nov. by smooth area limited to basal area of frons and genae or the whole head finely rugo-punctate, presence of promesonotal and metanotal groove, and absence of smooth surfaces on mesosoma.
