As GeckPhotographer pointed out, the red upper half of the iris is a diagnostic feature that these are L. rothi. The lower half of the iris is a pale gold. They are capableof substantial colour change from pale cream to heavily mottled rich brown, as depicted in your photos. They have a fold of skin over the ear drum which has a narrow black edge to it. The backs of the thighs are black with yellow spots.
I have to admit that these guys are one of my all time favourite frogs. They are often amazing calm if you pick up a wild one and are truly intriguing in their character.
