摘要
本文采用体视显微摄影技术对斑腿蝗科４属６种蝗虫前肠形态结构及其分类学意义进行了研究。结果显示，该类群蝗虫前肠形态表现出了一些共性：ＺＩ区具有Ｖ形脊，ＺＩＩ区脊数目少，脊上齿行数较多，ＺＩＶ齿排列方式简单等，与斑腿蝗科其它类群明显不同，这也表明它们的分类关系较近。而在各区脊数目的多少，脊上齿的行数，及一定脊长上齿的个数等方面表现出的差异性，表明种属的特异性。并对伪稻蝗和卵翅蝗的分类地位进行了探讨。
The taxonomic significance of the foregut armature of 6 species of grasshoppers belonging to 4 genera (Catantopidae) has been studied using the stereo microphotograph with 7 illustrations. The result shows that the foregut armature of these grasshoppers exhibits some common features, such as V shape ridges in ZI, less ridges in ZII, more teeth on one ridge, simple arrangement of teeth in ZIV ect. All these distinctly differ form grasshoppers of other Catantopidae groups, and show they are closely related. The difference existing in the number of ridges on each region, teeth on one ridge and teeth for a given ridge length express the specialty of the genus and species. Therefore, the taxonomic position of the species Pseudoxya diminuta (Walk) and genus Caryanda is discussed.
