The genus Trichapus Friedenreich, 1881, previously synonymized with Cis Latreille, 1797 and treated as part of the Cis taurus species group, is here synonymized with Macrocis. In addition, we describe Macrocis monnei Lopes-Andrade, Souza-Gonçalves & Sandoval-Gómez sp. nov., the first species of Macrocis recorded from the state of Tocantins, in the North Region of Brazil.
