The types were collected in pine-oak forest, with the nests found under small stones at the base of pine trees. The ants formed little colonies, are very fast in their movements and not very aggressive. The queens were about to start the flight when they were collected on June 19, 2004, at approximately 10:30 am. Additional collections were made in mesophilic mountain forest (Vásquez-Bolaños 2007)
Identification
Vásquez-Bolaños (2007) - Placed into the Tetramorium tortuosum species group because it has antennae with eleven segments, spatulate sting appendages, petiolar node longer than broad, anterior clypeal margin with a median impression, propodeum with a pair of spines, striate mandibles, dorsum of head rugose, and scape index (SI) < 100. It differs from (other New World species of its group) Tetramorium hispidum, Tetramorium mexicanum, Tetramorium placidum, and Tetramorium spinosum by the brown head and gaster, and orange mesosoma, petiole, and postpetiole. This species is smaller than T. hispidum, T. mexicanum and T. spinosum, but larger than T. placidum. Pilosity on the head major of the eye diameter, pilosity on the scapes and tibiae is shorter than the diameter of the respective appendage.
