Montandon described fossils from Zuttyeh, Tabun, Skhul, Kafzeh as syntypes of Homo semiprimigenius palestinus. The name stems from Montandon's hypothesis that this taxon reflects hybridization between Neanderthals and modern humans. Chapter VIII concludes with,
"Il est vraisemblable que cet etre mixte (mais pluspres du Neandertalensis, tandis que le type de Brux, legerement neandertaloide tient tout de mem au Sapiens) se révélera en bien d'autres points que la Palestine. Systematiquement, ce sera soit un Homo primigenius palestinus, soit, en créant un terme spécificque pour l'échelon mixte, un Homo semiprimigenius, variete palestinus." (p. 215).
From the syntypes described, Campbell (1965), selected Skhul 1 as the lectotype. Campbell noted the name is an objective junior synonym to Palaeanthropus palestinus McCown & Keith, 1932. The name is thus available but objectively invalid.
