Description. Holotype male (Figs. 1–3). Length 20 mm. General tegument black with highlights from blue to green on head, ventral surface and legs; pronotum matt. Body with coarse and dense punctation, sparser and finer on elytra and abdominal ventrites; setae long, thin, denser and yellowish on thoracic ventrites and femora. Elytral colour from black to brown or coffee coloured with a pair of reddish maculae on each quarter: the first, second and the fourth pairs rounded, third irregular and transverse (Figs. 1 and 3); a pair of small and rounded maculae on the ventral surface on basal margin of epipleura (Fig. 2).
Head with punctation coarse and dense; frons rectangular and with dense white setae; antennal insertions with prominent dorsal margin (Fig. 4). Eyes almost elliptical, prominent, broader on lower half. Frontoclypeus strongly sinuate and projecting. Labrum feebly convex, bilobed and with coarse punctation. Mentum trapezoidal, coarsely punctate with setae less dense on middle and posterior regions. Antennae long, 7th antennomere reaching the anterior margin of pronotum when laid alongside; scape elongate, widening from the base towards the apex; pedicel shorter and rounded; antennomere 3–11 triangularly widening from the base with sensory fields large, shallow and rounded (Fig. 5).
Pronotum trapezoidal, 1.5x wider than long, middle of anterior margin rounded and moderately produced, with raised margin; disc flattened; lateral margin almost rectilinear; posterior margin almost the same width as the basal margin of elytra; posterior angles acute, well developed and dorsoventrally flattened (Figs. 1–3 and 6). Prosternum with coarse punctation, rugose near the anterior margin. Femora with setae as long as on abdominal ventrites. Tibiae with pair of well developed spines at the apex; short and sparse setae on the external face; protibia with short and thick setae on internal surface, denser (like a brush) towards the apex. Scutellum cordiform, as long as wide, black and shiny. Elytra with deep depression in the humeral region; margin of the apical third and part of the margin behind the mid length serrate, with small teeth; the pair of sutural teeth triangular and larger than the other teeth; disc with longitudinal rows of fine punctures; interstriae convex, distinctly parallel, well marked and with fine and sparse punctures (Figs. 1 and 3).
Abdomen with abdominal ventrite 1 longer than 2–4; abdominal anal ventrite with external margins well marked, smooth and without setae, posterior margin sinuate and with median angle open. Aedeagus with parameres weakly enlarged before apex, and slightly impressed at inner margin of apex; median lobe acuminated at the apex, sides straight (Fig. 7).
Type material. Holotype male: BRAZIL. Rio de Janeiro: Itatiaia, XII.1964, Seabra & Werner cols. (MNRJ). Etymology. The specific name refers to the colour (coffee colour) on elytra.
