四种竹蝗前肠形态及其分类学价值的研究（直翅目：网翅蝗科）

FOREGUT ARMATURE OF 4 CERACRIS SPECIES AND THEIR TAXONOMIC SIGNIFICANCE(ORTHOPTERA:ARCYPTERIDAE)

用体视双目显微镜对付蝗属４种蝗虫的前肠形态进行了观察和描述（附图４组），根据前肠内刺特征、脊的数目及其排列方式把前肠分为四区：ＺⅠ—ＺⅣ。认为这四区特征及贲门瓣结构是鉴别种的重要特征。并建议将思茅竹蝗和黑翅竹蝗提升为２个种。

The foregut armature of 4 species of grasshoppers(Arcypteridae:Ceracris)has been described using stereo microphotograph with 4 illustrations.Based on the type of arrangment of the ridges and cuticular armature of the foregut,four distinct Zones Z I ￣Z IV are recosnized and these alone with the structure of the proventricular valves appear significant characters in the recognition of species. The two subspecies Ceracris fasciata fasciata (Br.-W.)and C.fasciata szemaoensis Zheng were suggested to be two species.
