Adloff, 1908 "Das Gebiss des Menoschen und der Anthropomorphen" proposed the name Homo antiquus for the Krapania material. The name appears first on page 65, where Adloff writes, "Eine besondere Art würde der homo primigenius von Krapina repräsentieren, für welchen damit eine neue Bezeichnung erforderlich wäre (Homo antiquus)," which roughly translates to, "The Homo primigenius of Krapina would represent a special species, for which a new name would be necessary (Homo antiquus)."
There is potential confusion about the source citation, which is listed incorrectly in Campbell (1965). Campbell referenced Adloff, 1908 "Die Zahne des Homo primigenius von Krapina". There is no mention of Homo antiquus in this publicaiton. However at the end of the paper Adloff mentions his latest work. He says (roughly translated), "For the rest, I refer to my detailed work 'The Gebiss des Menoschen und der Anthropomorphen' published by Julius Springer in Berlin, in which I discussed the facts again in detail."
The name Homo antiquus is an objective junior synonym for Homo neanderthalensis var. krapinensis Gorjanovic-Kramberger 1902.
