Description: As a result of the first phylogenetic analysis of the Mecocephala group, Hypanthracos Grazia & Campos, 1996 is included to the Mecocephala group; H. meridionalis is redescribed, and four new species in three new genera are described: the genus Chimerocoris gen.n. is proposed to accommodate C. luridus sp.n., the genus Liscocephala gen.n. is proposed to accommodate L. fumosa sp.n. and the genus Triunfus gen.n. is proposed to accommodate two new species: T. carvalhoi sp.n. and T. incarnatus sp.n. The new taxa are distributed in Brazil and Uruguay. In addition, Ogmocoris Mayr, 1864 is redescribed, a lectotype is designated, and the genitalia of both sexes for O. hypomelas (Burmeister) are described for the first time. The standard terminology for the male genitalia of members of the Mecocephala group is proposed. Photographs, illustrations, and a distribution map are also provided for all the species.
