Mapuche weren't very Andean, they have lived on steppes of central Argentina and central Chile.

Tiwanaku can't be predecessors of Incas because they would be also medieval in this game's terms.
Generally speaking, in my opinion game - worthy cultures of Andes look like this (go on and research them)
Ancient:
Caral,
Chavin
Classical:
Nazca,
Moche
Medieval:
Inca! and besides that,
Wari,
Tiwanaku,
Chimu
Early modern:
Mapuche
Industrial & modern: sigh, we can take
Peru to neatly conclude the lineup, although let's be honest, it wouldn't be based on its global power

All of those cultures would be either Agrarian, Builder or Aestethe, with the possible exception of Inca if you go Expansionist way (but Agrarian and Builder are so tempting...) and Mapuche which basically have to be nomadic Militarists.
There are also cultures of Colombia.
Muisca (medieval) is definitely worthy of being a culture on their own. But I can't decide myself if you could make their Colombian ancestor culture from
Zenu,
Qimbaya and
San Augustin cultures which were nice but really small and "can't tell too much about them".
Colombian culture would be okay ("Gran Colombian culture" definitely sounds weird).
Argentine and
Brazil are obvious. Other South American states are very unlikely.
I honestly couldn't find any Precolombian culture from Brazil and Venezuela that would be big enough and advanced enough to 'feel right' for the scope of the game, but maybe that's just me. Brazil was really 'pristine' and underpopulated even before European diseases and joyful crimes. I mean, few millions of people in the country of 9m km2 is few times smaller density than modern Mongolia, Christ, and that's before smallpox. Did I deduce correctly that the reason it was so sparsely populated was inability to grow maize on a large scale in Brazil's conditions? Because otherwise it's hard for me to explain why did Andes develop so much and Brazil was stuck on hunter gatherer level. There was one exceptional culture I think, covering barely one percent of its area with its tiny civilization lol.
Anyway, we do have 10 cultures for South America before even reaching for Latin American states. Lack of Sid Meier's tyrannic need to find documented leaders for everybody does simplify such parts of the world greatly. Civ is basically forced to take Inca again and again and again, sometimes spicing things with Mapuche or Muisca.
