Identification
A member of the Polyrhachis continua species group in the subgenus Myrma
P. procera is similar to Polyrhachis continua but differs by its larger size and more pronounced striation of the head and thorax. P. procera has a clypeus that in profile is gently sinuate, with the anterior margin vaguely obtuse medially (entire in modern specimens). In contrast, the clypeus in P. continua is almost straight in profile, with only a shallow depression anteriorly and the anterior margin is distinctly truncate medially. The pronotal spines in P. procera are relatively long and slender and the lateral margins of mesonotal dorsum virtually flat and converge anteriorly. In P. continua the pronotal spines are distinctly shorter and the lateral margins of mesonotal dorsum are raised and converge posteriorly.

- procera. Polyrhachis continua var. procera Emery, 1897d: 581 (w.q.) NEW GUINEA. Combination in P. (Myrma): Emery, 1925b: 200. Raised to species: Kohout, 1998: 519.
Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.
Description
Worker
Kohout (2013) - Dimensions (syntype cited first): TL c. 12.40, 11.89-12.85 ; HL 2.90, 2.87-3.06; HW 1.93, 1.93-2.09; CI 66, 66-69; SL 4.28, 4.18-4.54; SI 222, 216-222; PW 1.86, 1.76-1.91; MTL 4.48, 4.43-4.79 (1+3 measured).
Queen
Kohout (2013) - Dimensions: TL c. 12.70; HL 2.93; HW 2.18; CI 74; SL 3.93; SI 180; PW 2.62; MTL 3.88 (1 measured).
Besides characters associated with full sexuality and the shorter pronotal and petiolar spines, the single alate queen resembles the workers very closely. The pilosity is somewhat denser, notably along the leading edge of the antennal scapes and the mesosomal dorsum.
