Missing Exterior Trim

[Rooter]

Hi All, Be gentle with me, first time user and confirmed technophobe

I have a small piece of exterior trim which has fallen off my car and need help identifying the part number or proper name? Its a short piece of trim which is located between the rear door and the wheel arch approx 6inch long x 2inch wide
Any ideas?
