Sites like Bulbapedia and Psypokes list Pokemon by body styles, but nowhere is explained when they were introduced or what their function is.
Are the body styles only a way to categorise species in the Pokedex (for example, you can organise Pokemon based on "shape" in Pokemon X/Y) or is there any more to them?

Actually, while Psypokes might not explain it (anywhere I can see with a quick search), Bulbapedia does. If you click the words "Body Style" above the body style icon of any given Pokemon entry, it is a link that takes you to the "List of Pokemon by body style" page which states:
So, no, body styles have no effect on game-play. They are just a different way of searching through the Pokedex. Useful if you are trying to assemble a themed team with certain visual qualities, or if you can't remember the name of a pokemon, but know vaguely what it looks like.
