Abstract
The monotypic genus Cylindrommata is revised, and three new species are described from Brazil. Cylindrommata aurantia sp. nov. is recorded from the states of Rio de Janeiro and São Paulo, and differs from other species principally by having the prothorax tuberculate at the sides, pronotum subplane and elytra orangish. Cylindrommata lustrata sp. nov. is from Minas Gerais, and has the prothorax without tubercles, rounded at the sides, and elytra short and black with dark-blue reflections. Cylindrommata susanae sp. nov. is from Minas Gerais, Rio de Janeiro, and São Paulo, and has the prothorax without tubercles, parallel at the sides, and elytra yellowish. A key to the species is provided, and all the species are illustrated.
