Rebutia (Aylostera) camargoensis was originally published in Succulenta 55(3): 41-2, the journal of the Nederlands-Belgische Vereniging Van Liefhebbers Van Cactussen En Andere Vetplanten by Walter Rausch in 1976.

Here is the text of the description in Latin as published, but you should look up the original for more details, including extensive additional notes in Dutch, plus photographs. The English translation below is my own.
