Every alien specias has mainstream as their top priority because almost every single alien species on the Mainstream Marvel Universe first originated Mainstream Marvel Universe.

The Chitauri originated from the Ultimate Universe, in Mark Millar and Bryan Hitch's Ultimates, to be more precise. Their invasion of Earth was the main plot point of this mini-series.

And as far as I know the Chitauri won't have a main rol in upcoming Infinity, the Skrull are the shapeshifting aliens that are going to appear in said event.

And technically the other universes (including Earth-616 and the Earth-1610's actual appearance, as the Ultimate Chitauri were never shown in their original form (only posing as humans) in their first appearance) are basing the appearance of the Chitauri of the Marvel Cinematic Universe version.

We are going by a similar way for which we put Ultimate Monica Chang as the main character in her disambiguation page.
