Thelocactus setispinus aka Ferocactus setispinus.

According to 'The Complete Encyclopedia of Cacti' by Rudolf Subik & Libor Kunte, the pollen of this species can be used to induce self-pollination of other unrelated cacti. Though, I'd argue you can do this with almost anything. i believe it can also be crossed with Astrophytum asterias, as you see the flower is very similar.

Thanks lewis.That's what I thought it was. I also have that book and thought that was an interesting fact about the pollen and pollination inducing properties. I have tried it on a few things without any noticeable effect. Just tried it on a SUPERKABUTO. Will post any results.

Isn't another synonym Hamatocactus?

I kinda like the old Hamatocactus Taxon, ...so that's the first name that comes to my mind. Wink

Nice plant Trig.
