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 6 View 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 6 View FIGURE 6 A–C) and elytral interstriae strongly wrinkled and lacking distinct punctures ( Figs 1 View FIGURE 1 E, 6A–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. 7 View 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.
