摘要
在对蝗总科１０３种蝗虫雌性下生殖板进行形态学研究的基础上，对蝗总科８个科以及斑腿蝗科的稻蝗属、伪稻蝗属、拟凹背蝗属、卵翅蝗属和剑角蝗科的卡蝗属，选择导卵器正面观形态等１５个性状，以蚱总科为外群确定性状的极性和状态，用Ｈｅｎｎｉｇ８６Ｖ１．５软件对它们的系统发育关系进行支序分类研究。结果支持刘举鹏１９９１年依蝗卵结构所提出的蝗总科分类系统，同时结果也表明稻蝗属、伪稻蝗属、拟凹背蝗属、卵翅蝗属和卡蝗属所构成的类群起源于锥头蝗科和斑腿蝗科之间，与剑角蝗科距离较远。蝗总科８科的起源关系应为：癞蝗科瘤锥蝗科锥头蝗科斑腿蝗科剑角蝗科斑翅蝗科网翅蝗科和槌角蝗科。
Based on
15 characters of female subgenital plates, the phylogenetic relationship among 8 families
(Acridoidea) and 5 genera: oxya Serv., Pseudoxya Yin et Liu, Pseudoptygonotus Cheng,
Caryanda Stl and Carsula Stl were analyzed using Hennig 86 V1.5. ie * and xs w methods
were used in the cladistic analysis, and Tetrigoidea served as outgroup. The results support
the classification system on grasshopper egg pods setup by Liu Jupeng, and also show that:
The phylogenetic position of group consisted of Genus Oxya Serv., Pseudoxya Yin et Liu,
Pseudoptygonotus Cheng, Caryanda Stl and Carsula Stl is between Pyrgomorphidae and
Catantopidae is far from Acrididae. The phylogentic trend of Acridoidea is Pamphagidae
Chrotogonidae Pyrgomorphidae Catantopidae Acrididae Oedipodidae Arcypteridae
and Gomphoceridae.
