What are the "significant" differences? The only known difference is that Ultimate Chitauri can shapeshift. But also, in the other versions of the race, it wasn't stated they can't shapeshift, it was only never shown, by now.

And I know that the other alien specias are placed under Earth-616 because: (1) they originated from that universe and (2) their most important presence was in said universe.

If we follow these criterica, the Chitauri should be place in Earth-1610 because they originated from Earth-1610 and their most important presence was in the Ultimate Universe, were they were the main antagonists of the Ultimates in a big part of the the 13-issued mini-series Ultimates, trying to invade Earth after Captain America interfered with their plans in the '40s, on the other hand, Earth-616's Chitauri only appeared in Nova having kidnapped the father of the protagonist.

And as far as I know, if someone was to look up for the Chitauri, they'll look for their Marvel Cinematic Universe version, because they were the prominent villains in certain movie blockbuster, and not their Marvel Universe version, who only appeared as the antagonists in Marvel's 60th series on sale. The appearance of Earth-616's Chitauri are based of Earth-19999's Chitauri after all. And I know people that would like to know where did these "Chitauri" came from, from the Ultimate Universe.
