Etymology. In honor of Dr. Juan Pablo Botero who helped with discussions about this species.

Remarks. Beraba boteroi sp. nov. is similar to Beraba cheilaria ( Martins, 1967) ( Figs 15–17 View FIGURES 15–23 ), which we examined eight specimens, including both males and females and the holotype. However, it differs as follows: frons not depressed and sparsely punctate laterally; antennomere III rounded, not longitudinally sulcate dorsally; pronotal sculpturing well marked; black maculae on pronotum not restricted to the tubercles; and eburneous maculae on the posterior half of elytra without erect setae. In B. cheilaria , the frons is depressed and confluently punctate laterally, the antennomere III is flattened and slightly longitudinally sulcate dorsally, the pronotal sculpturing is distinctly shallower and less conspicuous, the pronotal black maculae are restricted to the tubercles, and the eburneous maculae on the posterior half of elytra have erect setae. The new species differs from Beraba odettae Martins & Galileo, 2008 ( Figs 18–20 View FIGURES 15–23 ) by the eburneous maculae on the posterior half of elytra without erect setae (present in B. odettae ), pronotal punctures finer and not partially confluent on the center of the posterior half (coarser and partially confluent in B. odettae ), and apex not darkened (darkened, especially on area of outer angle, in B. odettae ). Additionally, in the holotype male of B. odettae , the scutellum is shorter and vertical basally (longer and slightly inclined in the holotype of the new species). It also resembles Eburella cauera (Galileo & Martins, 2000) ( Figs 21–23 View FIGURES 15–23 ) but differs by the presence of distinct tubercles on the pronotum (absent in E. cauera ).
