This species can be distinguished by the mesoscutum with a strong median sulcus (deeper than half the median ocellus diameter), and also covered with erect setae longer than the mid ocellus diameter. The only female has a black metasoma and tegulae dark amber, different from other species that have red and orange tints. The vertex has irregular carinae directed to the mid ocellus. Males are not known.


According to Greek mythology, Tartarus is the deep abyss that is used as a dungeon of torment and suffering for the wicked and as the prison for the Titans. The name is used as a proper noun in apposition.
