I think you mean amer-indian indigenous, only because Russia has many indigenous ethnic groups so does Finland, new Zealand, USA Australia Papua New Guinea is exclusively indigenous and Brazil has a huge amount of indigenous peoples in the Amazon rainforest as do Ecuador and Peru. In Siberia Russia alone there are hundreds of indigenous groups. So you need to change the title to Latin American countries with amer-indian indigenous groups and add Brazil , Ecuador and Bolivia .
The definition of what constitutes indigenous could easily be argued though.
