Worker
Kohout (2013) - Dimensions (holotype cited first): TL c. 10.18, 9.42-10.68; HL 2.50, 2.31-2.59; HW 1.81, 1.65-1.87; CI 72, 70-74; SL 3.48, 3.12-3.48; SI 192, 181-192; PW 1.53, 1.53-1.87; MTL 3.68, 3.22-3.68 (1+10 measured).

Queen
Kohout (2013) - Dimensions: TL c. 11.04-11.29; HL 2.62-2.68; HW 2.09-2.12; CI 79-80; SL 3.38-3.43; SI 162; PW 2.37-2.40; MTL 3.33-3.48 (2 measured).

Queen larger than worker with usual characters identifying full sexuality, including three ocelli, complete thoracic structure and wings. Pronotal spines distinctly shorter, only about 2x as long as basal width. Mesoscutum wider than long; lateral margins converging anteriorly into narrowly rounded anterior margin; median line distinct; parapsides virtually flat anteriorly, weakly raised posteriorly; mesoscutum in profile with relatively low anterior face rounding onto weakly convex dorsum. Mesoscutellum only weakly convex, not elevated above dorsal plane of mesosoma. Propodeum with lateral margins terminating in medially directed, short ridges; propodeal dorsum descending into steeply descending declivity in medially uninterrupted line. Petiole with dorsal spines distinctly shorter, inner margins forming ‘U’-shaped dorsum of segment. Sculpturation, pilosity, pubescence and colour scheme very similar to worker.
