摘　　要：比较研究了螽斯科4属12种上颚与下颚内颚叶的形态结构。研究结果表明,草螽属的种类上颚较粗短,切齿较钝;钩顶螽属的种类,上颚粗壮,切齿呈刀状;日本似织螽上颚的切齿与臼齿相似,分化不明显,形成1排尖的齿状结构;所研究的种类上颚臼齿部相似,由3枚齿围成三角形。下颚内颚叶端部具2枚细长、端部较尖的内颚叶齿,通常具1枚较长的内颚叶齿突,日本似织螽内颚叶齿突短小,不明显。The structure of mandibles and maxillae of 12 species,belonging to 4 genera of Tettigoniidae from China are studied and the following results are found.The mandibles of the genus Conocephalus are strong,their incisor areas bear blunt dentes.The mandibles of genus Ruspolia are short and strong,their incisors look knife-shaped.The mandibles of Hexacentrus japonicus are elongated,the morphology of incisor and molar is similar,which resemble a row of sharp dentes.The molar area of all species is alike,with 3 dentes forming a triangle area.The maxadentes of lacinia usually prolong,apices of which are sharp;the hamadens is slender,but in Hexacentrus japonicus,the hamadens is very short and obsolete.
