Abstract

The genus Macrocis Reitter, 1878, is reinstated to accommodate the species previously placed in the Cis taurus species group, as follows: Macrocis bahiensis (Pic, 1916), new combination; Macrocis cornelli (Lawrence, 1971), new combination; Macrocis diabolicus Reitter, 1878, reinstated status; Macrocis grandicornis Pic, 1917, reinstated status; Macrocis longipilis (Pic, 1930), new combination; Macrocis pubescens (Friedenreich, 1881), new combination; Macrocis rufescens Pic, 1922, reinstated status; Macrocis setifer Gorham, 1883, reinstated status; Macrocis taurus Reitter, 1878, reinstated status; Macrocis testaceimembris Pic, 1916, reinstated status; and Macrocis testaceus Pic, 1916, with the unnecessary replacement name Cis kawanabei Lopes-Andrade, 2002, proposed as its junior synonym. 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.
