Spell-Like Abilities (Sp) + Arcane Armor Check Failure

[Phasics]

I know the answer in 3.5e which is that Sp abilities don't have Verbal, Somatic etc etc components and therefore armor does not interfere with their use.

However I could not for the life of me find the rule in Pathfinder that mentions it, no doubt its in a section I haven't thought to look.

It's in the Bestiary 1.

Also in the Magic chapter.

Spell-Like Abilities: Usually, a spell-like ability works just like the spell of that name. A spell-like ability has no verbal, somatic, or material component, nor does it require a focus. The user activates it mentally. Armor never affects a spell-like ability's use, even if the ability resembles an arcane spell with a somatic component.
