Biology

All known Azteca species are arboreal, nesting in living or dead wood, or external carton nests. Some species exhibit obligate associations with myrmecophytes, especially of the genus Cecropia (see Chapter 14 of The Ants). Feeding habits are generalized with foraging occurring both arboreally and on the ground.

Description

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.
