Worker
Longino (2007) - (n=2): HLA 1.22 (1.11–1.32), HW 1.21 (1.11–1.30), SL 1.11 (1.03–1.19), CI 99 (98–100), SI 92 (90–93).

Compared to Azteca pilosula and Azteca aurita, head relatively broader (CI > 105 versus < 106), posterolateral margins of vertex more rounded and cordate, not as angulate. Compared to A. pilosula, A. lallemandi has a deeper, more convex posteroventral petiolar lobe.

Queen
Longino (2007) - (n=4): HLA 1.27 (1.22–1.32), HW 1.22 (1.21–1.30), SL 1.18 (1.13–1.27), CI 99 (95–99), SI 94 (90–96).

Palpal formula 4,3; middle and hind tibia lacking apical spur; mandible strongly flattened, apical tooth much longer than penultimate tooth, dorsal surface smooth and shiny, pubescent; medial clypeal lobe strongly convex and protruding, extending well beyond lateral clypeal lobes; head quadrate, sides flat and diverging posteriorly, posterior margin strongly angulate laterally, deeply excavate medially; petiolar node short, bluntly triangular; posteroventral petiolar lobe deep, strongly convex from front to back, laterally compressed and tectiform; lateral and posterior margins of head, mesosomal dorsum, dorsal and ventral margins of petiole, and gaster covered with uniform vestiture of short, dense, white pilosity; scape and legs lacking erect setae; entire body orange, with smooth, highly polished and reflective surface.
