Andean dark constellations are called 'yana phuyu' in Quechua, which literally translates to 'black cloud'.
Notes on verification
Multiple independent authoritative sources (Smithsonian National Museum of the American Indian and Astronoo.com) confirm both the Quechua terminology and its literal translation. The sources are credible and corroborate each other on both key elements of the claim.
