Torvoneustes mexicanus was named by Barrientos-Lara et al. (2016) [ Torvoneustes species with a unique combination of characters, including robust teeth lingually curved with bicarinated conical crown, carinae bearing microscopic isomorphic denticles well defined (microziphodont condition); acute tooth crown apices; tooth enamel on basal two-thirds of the crown are heavily ornamented with long and thick apicobasal ridges that are uniformly spaced to each other; ridges near to the crown apex become short, drop-shaped tubercles randomly distributed, anatosmosed, and extended up to the carinae. ]. Its type specimen is IGM 9026, a partial skull ( fragment of cranium including part of the maxillae and dentaries showing 12 teeth in oclussal position, and splenials forming the mandibular symphysis ), and it is a 3D body fossil.
