新疆两种星翅蝗外生殖器的比较研究

对意大利蝗、黑腿星翅蝗两种星翅蝗雄性外生殖器、雌性下生殖板进行比较解剖，并描述其形态特征。结果表明，两种星翅蝗雄性外生殖器变化最为明显的部位是阳具基背片的侧板及阳具复合体的色带基支、色带瓣、阳茎端瓣。两种星翅蝗雌性下生殖板变化最为明显的部位是下生殖板的前突基内支及腹产卵瓣腹基瓣片。外生殖器特征在意大利蝗和黑腿星翅蝗存在明显差异，可作为两种蝗虫区别性状。

Comparative Study on the External Genitalia of Two Species Grasshoppers of the Genus Calliptamus in Xinjiang

The analysis on the male genitalia and the female subgenital plate of two grasshopper species：Calliptamus italicus （L.）and Calliptamus barbarus （F.-W）was conducted and its morphological fea-tures were revealed.The results showed that there were distinct differences in the epiphallus side plate and phallic complex rami of cingulum,valves of cingulum and apical valves of penis of the male genitalia and in the internal branch of AC and Ventral basal disc piece of ventral valvulae of the female subgenital plate be-tween the two species.There were significant differences of external genitalia between Calliptamus italicus （L.）and Calliptamus barbarus （F.-W）.
