Material examined: Paratypes: BRASIL: Pernambuco. Serra Negra. V- 1960. ABM Machado.leg [1 ♂, 1 ♀ MZSP]; Additional specimens: Floresta. Serra Negra. Cow dung. Wet Forest. VII- 2012. RV Nunes & GM De-la- Torre [3 ♂, 2 ♀ CEMT]; Floresta. Reserva Biológica Serra Negra. XII- 2012. RV Nunes & GM De-la-Torre [4 ♂ CEMT].

Diagnosis. This species is separated of the other species in the group by the following combination of characters: cephalic carina very low, with a weak pair of tubercles ( Figs 6View FIGURE 6 A –C); males excavation at the anterior portion of the hypomeron bearing few sparse setae; females excavation at the hypomeron very weak, almost absent; pronotal disc wrinkled and bearing deep punctures ( Figs 6View FIGURE 6 A –C) and elytral interstriae strongly wrinkled and lacking distinct punctures ( Figs 1View FIGURE 1 E, 6 A –B). This species has a detailed description in the work of Martínez and Pereira (1967) and therefore does not need a re-description.

Distribution. Since its description, D. machadoi  has been collected only in "Brejo de Altitude" forests at the Biological Reserve of Serra Negra, municipalities of Floresta, Inajá and Tacaratu Pernambuco, Brazil ( Fig. 7View FIGURE 7). The Brejo de Altitude forests are moist forests found on the higher parts of hills and plateaus in the Brazilian Caatinga, a semi-arid brazilian biome.
