摘　　要：研究表明杂食性的优雅蝈螽、暗褐蝈螽、中华螽斯、中华寰螽上颚相对较长,切齿尤其端齿较尖;臼齿简单;下颚内颚叶较狭,内颚叶齿较细;植食性的纺织娘、日本纺织娘、中华翡螽和绿背覆翅螽上颚粗短,块状,切齿较短,端齿不明显;臼齿结构复杂,显著隆起;下颚内颚叶较宽,端齿粗壮。推测下颚内颚叶在取食过程中仅起辅助作用。The paper studies the morphology of omnivorous katydids, Gampsocleis gratiosa, G. sedakovii,Tetligonia chinensis, Atlanticus sinensis, and herbivorous sinicus and Tegra novaehollandiae viridinotata. The results show that mandibles of the omnivorous katydids are comparatively long, incisors have acute apices; molar area is simple, indistinctly protruding; the lacinia isnarrow, apical teeth are thin and acute. The herbivorous kaydids bear robust mandibles, the incisors are short, the first one is usually not distinct; the molar area is complex and projecting. The lacinia is more broader, apical teeth are broad with acute apices. We speculate that the lacinia plays a supporting role during feeding process.
