No morphological differences between Chinese and Vietnamese individuals including fastigium verticis, tenth abdominal tergite, subgential plate, cercus and obvious transverse groove in metasternum ( Fig. 6A ~H). Male pronotum relatively longer than that of female. Female subgenital plate transverse with sclerotised lateral and membranous central parts as described in Ingrisch ( Fig. 6G ).

Coloration. Brown to yellow and green. More or less brown irregular spots on tegmen ( Fig. 5A, B ). Nymph yellow with lateral side brown from head, pronotum to abdomen ( Fig. 5C ).

Measurements.

Male: body 28.08–28.51, pronotum 11.68–12.14, tegmen 14.83–17.07, postfemur 18.11–19.63;

Female: body 24.24–25.43, pronotum 9.13–10.28, tegmen 17.20–19.62, postfemur 17.92–20.36, ovipositor 15.94–16.42.
