Solifugae, an order of Arachnida, also known as camel spiders, wind scorpions or sun spiders
Chelypus barberi Purcell 1902 (=Chelypus macronyx Hewitt 1919) - Northern Cape, Namibia, Botswana, Angola, Zimbabwe and Zambia - "On some South African Arachnida belonging to the orders of Scorpions, Pedipalpi and Solifugae".
Previous synonyms of this lineage are rejected; "Caulogastra Pocock, 1893" refers to pedicel, which is symplesiomorphic for the lineage and convergent with Solifugae, and "Arachnidea Van der Hammen, 1977" is easily confused with Arachnida.
