Phyllotettix Hancock, 1902

Type species. Phyllotettix compressus ( Thunberg, 1815) .

Description. Body strongly compressed with surface finely rugose; head and compound eyes inserted below pronotum disc; antennal groove situated below margin of compound eyes; facial carinae placed between antennal groove; scutellum distinctly rounded and wider. Pronotum with radiating veins; crest highly elevated, with edge undulated or almost straight; anterior margin of pronotum elevated overhead, covering dorsally the head with a truncated projection or almost rounded extending down almost to the vertex portion; margin posterior of pronotum not truncated; infrascapular area visible and broad. Tegmina and wings absent. Fore femur undulated, middle femur elongated; hind femur robust, with dorsal margin excavated on distal portion ( Fig. 6 , 7 ).

Comments. Phyllotettix has three species: P. compressus ( Thunberg, 1815) , P. foliatus ( Hancock, 1902) and P. rhombeus ( Felton, 1765) . P. foliatus is the species described more recently. Otte (1978) listed the holotype housed at the ANSP, but we were not able to locate this specimen.
