Macronemus asperulus was described from Venezuela, and Aethomerus verrucosus from Magdalena in Colombia. Pascoe (1866) treated A. verrucosus similar to A. asperulus but more uniformly colored, the tubercles on the sides slender and prominent, and the spaces between the lines of tubercles on the disc more deeply excavated. Examination of the male holotype ( Figs. 33–34 ) of M. verrucosus , the female holotype of M. asperulus ( Fig. 35 ), and also a series of specimens ( Figs. 36–38 ) revealed variations in the color pattern, the degree of excavation of the pronotum disc, the shape of the prothorax lateral tubercle, the granules, and the punctures on the elytra. Based on this variation, we propose the new synonymy.
