Mammi to indentify. Thanks!

Hello everyone!

I put this mammillaria to identify here, it has 9-10-11 radial spines of beige color with dark tip, a very long central spine of brown / black color and a big pink flower.
When I was very small and I identified it here they told me that it is probably Mammillaria Papasquiarensis, I also thought the same thing but the color of the flower does not agree with the description of Papasquiarensis. Maybe Melanocentra, Sonorensis???

Pretty sure it is melanocentra
