Sathrophyllia is a genus of Asian katydid. They are usually found on the branches of bushes or trees where they sit close to a branch and spread out their forelegs and antennae along the branch and hold themselves close to the surface with their middle pair of legs. Some species like S. rugosa have cryptic colouration that matches the bark making them very hard to spot. Further east, the genus Olcinia also bears a close resemblance, however Sathrophyllia has a relatively smooth margin to the forewing unlike that of Olcinia.
