Looks like a Lobivia, now lumped into Echinopsis.

Some beautiful hybrid Echinopsis eg Cabaret, Temptress, Antares, Firelight etc

[greenknight]

Yep. There are so many of these hybrids that it's often impossible to determine which you've got if it's unlabeled. I really love the color of this one, though, wish I knew its name.

Thanks both. You guys/girls rock !

I would also say Lobivia, impossible to say at first glance what species it may be and/or if it's a hybrid
This comment needs correction though, since the DNA-research of Schlumpberger et al. in 2018 Lobivia is no longer lumped under Echinopsis

Lobivia acanthoplegma was the closest to a match that I could find, but it doesn't quite fit - I think it's more likely a hybrid.
