The habits of the species are probably similar to those of fissa or decemdentata and its range probably covers the same area as these two species, that is, the forest zones of West and Central Africa. (Bolton 1973)
Rigato (2016) - A small militaris group species with trapezoidal head, the lateral pair of petiolar spines a little longer than the dorsal pair, and scape devoid of standing hairs.
Bolton (1973) - P. phidias is most closely related to Polyrhachis fissa and its immediate allies as is shown by the petiolar structure and the development of the pronotal spines. It differs from them in details of sculpturation and petiolar structure.

|Number of countries occupied by this species based on AntWiki Regional Taxon Lists. In general, fewer countries occupied indicates a narrower range, while more countries indicates a more widespread species.|
|Relative abundance based on number of AntMaps records per species (this species within the purple bar). Fewer records (to the left) indicates a less abundant/encountered species while more records (to the right) indicates more abundant/encountered species.|

Bolton (1973) - TL 4.9-5.1, HL 1.18-1.26, HW 1.03-1.08, CI 85-87, SL 1.18-1.26, SI 114-116, PW 1.08-1.13, MTL 1.16-1.21. (2 measured.)
Anterior clypeal margin entire, somewhat flattened medially. Sides of head in front of the strongly convex eyes shallowly convex. Behind the eyes the sides are nearly straight and meet the convex occipital margin almost in a right-angle. Alitrunk marginate laterally throughout its length, the marginations broken only at the sutures. Constituent segments of the dorsum of the alitrunk shallowly transversely convex. Pronotum armed with a pair of broad, flattened, triangular spines, the outer edges of which form a continuous convexity with the lateral marginations. Sutures well developed on the dorsum, the metanotal groove impressed. Propodeum armed with a pair of small, blunt, upturned teeth. Petiole with a pair of long, acute, lateral spines and a pair of short, triangular, dorsal teeth. Anterior face of first gastral segment strongly concave medially.
Erect hairs present on all dorsal surfaces of the body, but absent from the antennal scapes. Pubescence short and grey in colour.
Head and dorsum of alitrunk finely longitudinally striate-rugose. The first gastral segment similarly but more finely sculptured and with numerous small punctures between the rugae.

Bolton (1973) - Syntype workers, Equatorial Africa (locality unknown) (Musee d'Histoire Naturelle Genève) [examined]. In the original description Forel stated that the locality in which the type series was captured was unknown, although “certainly in Equatorial Africa”. This last information is also included upon the data labels of the type specimens.
