Spix described Aratinga caixana as very similar to "the preceding species" in his book, i.e., his Aratinga flaviventer, the main plumage difference being some yellow secondary wing feathers in caixana. He did not provide any 'Habitat' statement for caixana, but suggested it was possibly but a variant of flaviventer, which he said was found in "Pyauhy" (= Piauí). <a href="http://biodiversitylibrary.org/page/35672072" target="_blank">Hellmayr 1906</a>, who studied Spix's types, identified both flaviventer and caixana as Conurus cactorum (Kuhl) (now Aratinga/Eupsittula cactorum), and suggested the caixana type was a partly albinistic specimen. ("Das Original von A. caixana trägt auf jedem Flügel einige ganz gelbe Armschwingen, also Zeichen von Albinismus.") Eupsittula cactorum is found only in arid eastern Brazil, not at all in the upper Amazon.I imagine that here the name might be a reference to the bright feather armbands that people from some South American native tribes (including the Caixanas?) wear--but this hypothesis admittedly does not rest on any hard evidence.</blockquote>
