Naming history
Sthenopis pretiosus was independently discovered, named and described at least three times:
- It was first found in Brasil and described by Herrich-Schäffer in 1856 who called it Epialus pretiosus. The type specimen of E. pretiosus has not been located.
- It was also found in the north-eastern United States and south-eastern Canada and described by Grote in 1878, who called it Hepialus auratus which become Sthenopis auratus.
- It was also found in Venezuela and described by R. Pfitzner in 1906, who called it Phassus eldorado. Latter R. Pfitzner published illustration of Phassus eldorado. The holotype of P. eldorado is at the Senckenberg Museum in Frankfurt am Main.
In 2015, Carlos G. C. Mielke and John R. Grehan concluded that Hepialus auratus Grote, 1878 and Phassus eldorado Pfitzner, 1906 are junior and subjective synonymies of Sthenopis pretiosus Herrich-Schaffer, [1856], and applied the rule of priority to change H. auratus and P. eldorado's names to Sthenopis pretiosus.
