Tiny white-backed frog - closeup, La Isla Escondida, Colombia
Including the uncropped shot in this series to show how impossibly tiny some of these frogs are. This one I estimate at about 2cm but don't consider that to be very accurate. Notable feature of this frog is the white back.
Identification in progress, no immediate match in my first search efforts so will ask for some help.
