摘　　要：研究了20种中国植食性螽斯的上颚与下颚内颚叶,结果表明,上颚粗壮,切齿较短,边缘锋利,种间形态差异较显著;臼齿部不规则,凹凸明显。下颚内颚叶均具2枚内颚叶齿,颚叶齿突较长,形态相似,推测下颚内颚叶不直接参与切割和研磨食物,主要起辅助性作用。This paper observes the morphology of mandibles and laciniae of 20 bushcricket species from China. The results show that the difference between species is distinct in morphology of mandibles,which is robust and massive and bears 3-4 comparatve shorter and stouter incisors with sharp knife-shaped edges. The molar area consists of some tooth-shaped projections. The lacinia is alike,has two teeth,and one long hamaden,we presume the lacinia plays a accessory role in feeding process.
