Worker measurements. Holotype (Paratype). HL 0.60 (0.50) HW 0.52 (0.46) SL 0.41 (0.38) EL 0.05 (0.04) WL 0.70 (0.63) GL 0.75 (0.70) TL 2.60 (2.33) CI 88 (92) SI 74 (82).
Worker diagnosis. Head longer than broad, with convex posterior and evenly rounded corners. Sides of head slightly concave before the eyes, slightly convex past eyes. Mandibles with 4 teeth decreasing in size from the apical teeth, the antepenultimate (subbasal) smallest. Mandible internal side with two lamelliform setae near basal border, between basal teeth and teeth of basal border. Hypostomal teeth absent. Head, most of promesonotum, sides of pronotum and gaster smooth and shining; remainder of thorax with more or less longitudinal rugulae. Posterior face of propodeum long, smooth and shining. Petiole with rugulae concentric around node, dorsally transverse and longitudinal on sides; sides of postpetiole with oblique rugulae, smooth and shining in the top, mandibles smooth and shining. Hairs long and flexuous on the body, shorter and appressed on antennae and legs. Body brown (including hairs), antennae and legs lighter.

Comments. Very similar to
A. longinodus
. Separated by the sculpturing on the propodeal dorsum and the sides of the mesosoma. In
A. boltoni
, the lamelliform setae are reduced to 2, near the basal border and between the basal teeth (of the masticatory border) and the tooth of the basal margin.
This species is known from Bahia (Brazil) and Tapua (Paraguay), which are widely-separated sites. The species will probably be found in other areas, when sampled with Winkler traps and Berlese funnels.
