Unless there's something you would specifically want that Capoerists would get, I don't think you'd need a prestige class. Just fiddle with an existing class.
Take a basic fighter. Ask your DM to let you, in exchange for getting rid of Light, Medium, and Heavy Armor Proficiencies, and Shield Proficiency, to instead let you get a good Reflex save, and an AC bonus like the monk (something like +1 every 4 levels).
Then, just take the appropriate feats, maybe make some new feats, and add some flavor to the character. You have improved unarmed strike, expertise, and improved trip, definitely. Take maybe weapon focus in machete or just unarmed strike. Then just say that, while doing those spins, you're using expertise most of the time to make yourself harder to hit. Definitely take weapon finesse, too, and probably dodge. The rest is just how you define yourself.
If you want a prestige class, it would need to be for something like a special group of Capoerists. Maybe they all sing while they fight, and all of them have trained with some sort of special lashing kick attack that gives them 10 foot reach but puts them off balance for a round. Give them a special backstory, and perhaps some common customs, and you're set. But always try to put at least some social element into your prestige classes.
