In hyperplatyrrhine noses, the nasal breadth may exceed the nasal length. In some cases, the nose may even be wider than the mouth. The most hyperplatyrrhine groups are found in Pygmoids of Central Africa, e.g. Mbuti and Twa. Equally wide are the noses in the Karoo steppe of South Africa, e.g. in Khomani, and also some Australia Aboriginals of the Western Desert and Arnhem Land. Hyperplatyrrhiny in slightly lower frequencies occurs throughout most of Sub-Saharan Africa from Sudanids to Khoids and Bantuids. The New Caledonians (in Melanesia) and the extinct Tasmanian natives often show hyperplatyrrhiny as well.
