Arackar's fossils were first discovered in 1993 but not named until 2021, by Rubilar. The full binomial name, Arackar licanantay, translates to "bones of the Atacamenians" in the Kunza language.

This clade is sister to another clade consisting of the Opisthocoelicaudiinae and Trigonosaurus+Saltasaurinae.
