摘　　要：通过对5属16种盗猎蝽发音器细微结构的扫描电镜观察现发:(1)所有被研究的属种均具发音器。其形状分为三类:①宽型 发音沟的宽:长=1:8,横纹摩擦脊的数目在14O左右;②中型 宽:长=1:15.5～18,横纹摩擦脊数目在260～330之间;③长型 宽;长=1:21～43,横纹摩擦脊数目变化幅度很大,多数中国产盗猎蝽亚科的种属均属此型。(2)不同的种其发音器在形状、脊的数目及脊的结构上有一定的差异;例如乌黑盗猎蝽Peiratesturpis Walker与短翅盗猎蝽p.(p.)brevialatus,新种为非常相近的两个种,但其发音器的结构迥然不同。(3)发音器的构造具有雌雄二型现象,但同性的不同个体间结构一致。以上清楚地表明发音器的细微结构在近缘种的分类上是一个非常有用的特征,但在盗猎蝽亚料的属级分类上意义不大。Scanning electron microscopy was done on the stridulatory furrow structures of Chinese Peiratinae. The evidences indicate thati (1) all the 5 genera studied(.Phalantus Stal, Eciomocoris Mayr, Lestomerus Amyot et Serville, Peirates Serville, and Sirthenea Spinola) have a stridulatory furrow, and can be divided into 3 types) (2) different species have different stridnlatory furrow structures in shape, number of transverse striae, and transverse striae themselves) (3) they exhibit sexual dimorphism)(4) the stridulatory furrow structures are very useful in distinguishing closely related species but of little use in taxonomic studies of the generic level.
