After Alphonse. F. Renard (1842-1903), University of Ghent, Belgium.
Described as a new species from Shinkolobwe, Democratic Republic of Congo by Schoep (1928). Later Deliens et al. (1990) argued that it was a mixture of dewindite and phosphuranilite. Sejkora et al. (2003) investigated specimens from Rýžoviště, Haarachov, Böhmen, Czech Republic and concluded it to be a valid species. However, further investigations are needed. Currently (2015), the species is listed by IMA as questionable, with formula different from that of dewindtite.

The crystals of renardite described from Shinkolobwe resembles dewindite ( Schoep 1928).
