Non-core post - native peoples from where?

Just after finishing the readings for this week I (re)watched an X-files episode that totally relates to SBW's article. The episode (season 3, e 18) is about the uncovering of an artifact in the "Ecuadorian Highlands" that is then brought to Boston despite the plight of the native people who claim that it represents the spirit of a female shaman and don't want it to go. The plot of the episode is somewhat conflicting in the sense that while it raises the issue of appropriation of native culture, it does so in the most cliched way (the principal scientist is the whitest American called Dr. Roosevelt) and the aftertaste of the episode is but a reinforcement of the stereotype of the "mystical" native people.
The reason why it reminded me of SBW analysis of Dora is because here too there is a collapsing of  everything that seems Latin American ("pan-Latin"). Firstly, the episode is called "Teso dos Bichos" which is in Portuguese but this language is not spoken in Ecuador (in fact, it is only spoken in Brazil) - not to mention that it snows during the initial scenes and it very rarely snows in Ecuador. Secondly, the "secona people" as they call it in the episode do not in fact exist, they are called the Secoya people and inhabit the tropical region of Ecuador, not the cold highlands. Thirdly, the "brown characters" they depict as the "Secona" are an example of race "not rendered invisible, but [...] also not presented as specific and particular" because they are all dressed differently and exhibit markers from different native peoples and none too specific. Not to mention that the music used in the episode for the ritual scenes is music from the North American native Indians, not the kind you would associate with natives in South America.
