Giuffrida-Ruggeri (1921) established the new species meridionalis and moved the subspecies proto-aethiopicus to it. Campbell (1965) lists the name as an available objective junior synonym to Homo aurignacensis hauseri Klaatsch and Hauser, 1910.
Under Article 32.5.2.3 the subspecies name proto-aethiopicus should be corrected to protoaethiopicus.
