That's "Bokina"...
Actually, there is another "Bokina" - the nearly identical Vivitar Series 1 90/2.5 Macro (and its matching 1:1 Macro Adapter). The older VS1 90/2.5 Macro was also made by Tokina to the same optical specs, so, despite the fact that the VS1 lens is not branded as a Tokina, it is also often referred to as a "Bokina", too.
The ATX and the VS1 are both superb macro lenses and superb portrait lenses.
Personally, I slightly prefer the Tokina ATX with a Ka mount (the Tokina was made with both a K mount and a Ka mount) for exposure simplicity (the VS1 came with only a K mount), and I think the ATX coatings are perhaps slightly better than the VS1 coatings, plus the ATX focuses "the Pentax way", while the VS1 focuses in the opposite direction. [The VS1 comes with a tripod mount on the adapter, while the ATX does not, but I don't think that's really important due to the sizes of the lenses.]
