Type locality. Brésil.

Diagnosis. The acutely notched external side of each clypeal tooth will place this species in Coprophanaeoides . Within Coprophanaeoides , the glabrous clypeus and pronotum will separate it from all other species except D. bluti , which has smaller eyes, D. inflatus which has atrophied elytral striae and D. pauliani which is known from Bolivia.

Natural history. The very few specimens with data were collected at black light trap and one specimen was collected in cerrado sujo.

Remarks. Males differ by the higher and narrower clypeofrontal carina and by the shape of the anterior pronotal carina which is tuberculate medially and the pronotum having a depressed area posterior to the anterior carina. The distinctly more slender first posterior tarsal segment will also separate males. Parameres are simply rounded apically in dorsal view and tapering in lateral view, the surface is lacking distinct microsculpture and minute tubercles apically (Figs. 52–53).

Variation, as usual, occurs in the extent of the metallic marking on head and pronotum. The greenish tinge is also variable and being very faint in teneral specimens. In some individuals the pronotum is showing some coppery and yellowish metallic tinge. The degree of coarseness and density of punctures on all surfaces is also variable and in some specimens the elytral interstriae are showing some larger irregular puncture and irregular patches of microsculpture along striae. The entire range of variation can be found in specimens from the same collecting event, therefore we are considering this variation as intraspecific.

Nomenclature and taxonomy. D. refulgens olsufieffi Blut, 1939 = D. renatii Olsoufieff, 1924 , new synonymy. The holotype of D. refulgens olsufieffi was examined and compared to the holotype of D. renatii and differs by its larger size, slightly more coarsely punctate pronotum and elytra and more intense green metallic sheen. However, no other characters could be found to support this slight variation as a distinct species. As stated by Blut, he did not study the type of D. refulgens , and obviously misidentified as D. renatii a specimen which he studied. The specimen identified by Blut as D. renatii is in fact and new taxon described herein as D. bluti .
