| Etymology | Named after the Acheron River in Greek mythology. According to the old Greek myth Acheron was tributary of the Styx River, in which the boatman Charon crossing the earth souls into infernal regions. The word acheronius is used herein in allusion to the type locality (= Black River in English) as well as in reference to the secretive habits of the new species. |
