内蒙古菊网蝽属成虫体表感觉结构的扫描电镜研究(异翅亚目:网蝽科)

An Observation of Some Sensory Structures of Adults of the Tingis Fabricius from Inner Mongolia Under Scanning Electron Microscoup

对内蒙古菊网蝽属Tingis Fabricius 12种网蝽的雄雌成虫体表感觉结构(包括瘤突及感觉窝等)植行了扫描电子显微镜观察研究,揭示了该属昆虫体表感觉结的形态结构特征及其在分类学中的意义。研究结果表明,网蝽成虫体表感觉结构不仅在不同亚科、不同族、不同属之间有所区别(Rodrigues 等,1982),而且在亚属和种的水平上也存在着一定的差异。在内蒙古菊网蝽属的两个亚属Neolasiotropis 和Tingis 之间,主要区别表现在瘤突的疏密、间距、感觉窝的数目以及感觉窝内小突起的形状和排列形式、无感觉结构光滑区的形状等方面;在同一亚属的不同种之间,相近种之间感觉结构的差异不明显,因而在一定程度上能够反映其亲缘关系。

The present paper deals with observation of some sensorystructures (including sensory ncdules and pits on tergum of abdomen) ofadults of 12 species lacebugs of Tingis Fabricius in both sexes,under thescanning electron microscoup,demonstrating the morphological structurecharacters of them and their bearing in classification.The study showresults that there exist differences of the senscry structures of thelacebugs not only between different subfamilies,different tribs and differnet genera(Rodrigues etc.,1982),but also between differentsubgenera and different species.Between the two subgenera Tins Neolasiotropis and Tingis Tingis of Tingis Fabricius of Inner Mongolia,maindifferences are shown in scatteling degree and distance between the sensorynodules,numbers of the sensory pits on certain tergum and the forms andarranging pattens of little noduli in the pits,and that of smooth areawithout sensory structure.The difference between close related lspecies insame subgenus is rot obvious,as can show the relationship between thespecies to a certain extent.
