Is this M. haageana ssp. acultzingensis

I got this one as a gift when I bought plants from Ebay. I was looking through The Cactus File handbook: Mammillaria And came across this name. The description fits.

Hello Sandi,

This looks more like M. rhodantha to me with the upwards curving spines.

Hello Sandy,
I agree with Hugo.
On the first view, a similarity exists, but it is really not M. acultzingensis but indeed M. rhodantha.
M. acultzingensis has maximun 2-4 central spines and no bristles in the Axils.
On your first picture I believe to be able to count up to 6 central spines, and I believe to be able to recognize bristles in the Axils. Moreover, M. acultzingensis flowers not in truly closed wreaths and always opens only few at the same time.
Greetings
Holger

Hello sandy,
I also think it is rhodantha.

Ok, thanks for your help.
