中国的光肩星天牛类群

该文讨论我国光肩星天牛Anoplophoraglabrlpennis(Motschulsky)类群的外部形态和外生殖器的主要鉴别特征，寄主、地理分布、起源及其演化。光肩星天牛主要分布在山西吕梁山、太行山以东的广大平原地区，寄主广泛，主要有榆、复叶槭、杨、柳、五角枫等。黄斑星天牛主要分布在秦岭以北，山西吕粱山太行山以西的陕甘宁地区，向东已扩展到河南、河北；主要为害杨树，也为害柳、榆。四川星天牛主要分布于秦岭以南的西部地区，北限在陕西太白山到甘肃天水一带；主要为害柳。在秦岭以北到天水之间是黄斑星天牛和四川星天牛的重叠分布区，山西太行山两侧南北走向的狭长地带是光肩星天牛和黄肩星天牛重叠分布区，两个狭长地带交会处，大约在秦岭以北的陕西和(或)山西境内有三个种的重叠分布区域.在云、贵、川地区广泛分布着四川星天牛，至今还没有发现光肩星天牛、黄斑星天牛和蓝角星天牛，后者应该是一个值得怀疑的种。

THE GLABRIPENNIS SPECIES GROUP OF THE GENUS ANOPLOPHORA IN CHINA (COLEOPTERA:CERAMBYCIDAE)

The glabripennis species group of Anoplophora includes five species in China: a species in Taiwan and 4 species in mainland. They are: A. Flavomaculata(Gressitt), A. glabripennis (Motschulsky), A. nobilis (Ganglbauer), A. freyi (Breun-ing) and A. coeruleoantennatus (Breuning). The first one, a Taiwan species is not available to the authors, and the last one is a suspectable species, it is perhaps merely individual variation. This paper deals with the taxonomic characteristics of anatomy with the genitalia,host, distribution, origin and evolution of the group. A.Glabripennis (Motschulsky) is distributed mainly over Shanxi Province and the plateau of eastern Shanxi, its primary host being Populus, Salix, ulmus and Acer. A.Nobilis (Ganglbauer) is distributed mainly over Gansu, Ningxia and Shaanxi Provinces,north to the Qinling Mountains, its primary host being Populus. A. freyi (Breuning) is distributed mainly over Yunnan, Sichuan and Guizhou Provinces, south of Qinling Mountains, its primary host being Salix, but A. nobilis (Ganglbauer) and A. glabripen-his (Motschuksky) are not found in this region. The ranges of distribution of these three species overlap in Shanxi and (or)Shaanxi, about north of Qinling mountains.
