Distribution: Brazil ( PA new rec., RJ, SP new rec., SC, RS new rec.).

Remarks: The two species of the subgenus that present the evaporatorium not attaining the mesopleural lateral margin; can be differentiated for the number of secondary setigerous punctures on the submargin of mandibular plates along with the mesocorium surface, which is almost impunctate in D. americanus  ( Fig. 8 BView FIGURE 8) with only one primary setae close to the eye, while in D. foratus  is coarsely punctate and presents three secondary submarginal setigerous punctures on each mandibular plate.
