A member of the brevicornis species complex. Mackay (1996) - This species is apparently most closely related to Acanthostichus skwarrae. The petioles are almost identical in shape and are both smooth and highly polished. The two species are easily separated as A. skwarrae has no erect hairs on the dorsum of the petiole. In addition, A. skwarrae has possibly as many as 10 erect hairs on the dorsum of the mesosoma, the longest of which is 0.1 mm in length. The gaster of A. skwarrae is almost without hair, except for the area near the pygidium. The longest hair on the gaster is about 0.05 mm in length. Thus these two species appear to be very similar, but A. quirozican be easily distinguished by the longer and much more abundant erect hairs. It would not be likely to confuse this species with any of the other species, based on the shape and sculpture of the petiole. The unknown workers of Acanthostichus emmae should have a subquadrate petiole and larger eyes, and thus be distinguishable from this species.

Number of countries occupied by this species based on AntWiki Regional Taxon Lists. In general, fewer countries occupied indicates a narrower range, while more countries indicates a more widespread species.
Relative abundance based on number of AntMaps records per species (this species within the purple bar). Fewer records (to the left) indicates a less abundant/encountered species while more records (to the right) indicates more abundant/encountered species.

Holotype worker (Universidad Nacional Autonoma de Mexico) and 8 paratype workers (2 headless) (The Natural History Museum, William and Emma Mackay Collection, Fundacion e Instituto Miguel Lillo , Museum of Comparative Zoology, Museo de Historia Natural, Bogata, Instituto de Zoologia Agricola, Museu de Zoologia da Universidade de Sao Paulo), MEXICO, Veracruz, Tuxtlas, 28-viii-92, L. Quiroz.
Named in honor of my good friend and fellow “mirmecologo” Luis Quiroz of the Instituto de Ecologia (Mexico), who has sent me specimens of this species as well as numerous other interesting ants.
