Azteca tonduzi is an inconspicuous species which nests in hollow dead stems and sometimes forms carton nests among epiphytes. The types were collected in orchid pseudobulbs (Forel 1899). In Costa Rica I have collected this species multiple times. A dealate queen was in a dead branch of Ficus werckleana, a colony inhabited dead branches of Terminalia catappa along a beach edge, a colony inhabited dead culms of Uniola (sea oats) at the edge of a mangrove swamp, and workers were in small carton nests over coccoid Hemiptera on a branch of Licania. The largest colony I have observed was in a mangrove swamp near the mouth of the Rio Llorona in Corcovado National Park. Workers were very abundant, nesting in bases of several species of bromeliads. On the mangrove branches and trunks there were carton shelters containing brood and coccoid Hemiptera. The colony spread across multiple trees of Avicennia and Laguncularia. Alate queens have been encountered flying during the day and occasionally at blacklights. (Longino 2007)

Longino (2007) - The queen is distinguishable from other species by its small size. Workers are superficially similar to small workers of Azteca velox, Azteca nigra, Azteca flavigaster, Azteca gnava, and Azteca sericeasur, but differ in the palpal formula being 5,3 instead of 6,4.
