Huang et al. (1982) proposed the name Homo erectus hexianensis based on the partial cranium from Longtan Cave, Hexian, China. Huang et al. (1982) provided a brief description and comparison with other taxa, including Pithecanthropus. The original text is written in Chines with an English language summary. The summary included the following lines proposing the new name, "Morphological features shown by the skull discovered in Longtan Cave suggest it belongs to the Pithecanthropus stage. In view that the main features of Hexian man make himself relate different with Java man and Peking man, it is reasonable to attibute the Longan Cave skull to a new subspecies and assign it the provisional name Homo erectus hexianensis" (p. 256). Huang et al. (1982) explicitly indicate the name is provisional and therefore unavailable. Groves (1989 p. 282) treated the name as an available junior synonym of Homo erectus pekinensis. Curiously, although Groves (1989 p. 202-3) noted the provisional nature of Homo lantianensis, in the following sentence he fails to note the provisiional status of Homo erectus hexianensis.
