Weidenreich (1944) writing on behalf of von Koenigswald due to the loss of communication stemming from the Japanese occupation of Java related several discoveries from Java including the "1937" mandible, the "1939" mandible and the "1941" mandible (= Sangiran 6 = Meganthrpus A). The latter he indicated was the holotype for Meganthropus palaeojavanicus von Koenigswald, 1944.
Weidenreich (1944 p. 480) wrote, "Von Koenigswald, recognizing at once the human character of the fragment and, of course, also its gigantic proportions, gave the type the name Meganthropus palaeojavanicus. So far we have no other word from von Koenigswald, but by labelling the specimen in this way he makes known that he con- siders the type represented by the jaw as a giant hominid different from Pithecanthropus."
Given this statement, and the prior anatomical comparisons included in this publication it seems Weidenreich (1944) is sufficient to establish the name and its attribution to von Koenigswald.
Von Koenigwald (1945) further described the new species.
Robinson (1954 p. 198) moved the species to Paranthropus palaeojavanicus.
Campbell (1965) listed 1945 and 1950 as the authorship years though the Weidenreich Science paper was published in 1944. Campbell (1965) listed Meganthrpus palaeojavanics as available and valid, with the 1941 mandible as a lectotype.
Lovejoy (1970) provided a summary of the taxonomic status of Meganthropus.
Groves (1989 p. 201, 281) listed Meganthropus palaeojavanicus Weidenreich, 1944 as a subjective juniorn synonym for Homo erectus erectus. He indicated Sangiran 6 = Meganthropus A as the type
