FOREGUT ARMATURE OF GRASSHOPPERS AND THEIR TAXONOMIC SIGNIFICANCE (ORTHOPTERA: CATANTOPIDAE) |
| |
| Abstract: | 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. |
