From your photo that looks like a support brace between the body and the bottom of the wheel arch area, not part of the suspension, so the other side not having one probably isn't a big deal. The easiest way to get the proper name is to show the photo to a Peugeot parts counter with your reg or VIN. Has anything been replaced on that side before?
