Better word?

[wolfie-18.livejournal.com]

Hey, I wanted to know if there's a better word for "native" than "аборигенный?" I'm translating for a group of indigenous peoples in Mexico and a delegation from Central Asia, and the only other alternative I find is местный, which feels more like "local" than "indigenous." And аборигенный just sounds... sounds to my ear just like негр does, and I don't feel like insulting any actual indigenous peoples.

Thanks!
