长崎齿瓢虫属Afissula kapur 1955种类及地理分布的研究

长崎齿瓢虫属Afissula Kapur自1955年建立以来,近30年经各国学者不断地发现,有的重新组合到这个属,迄今该属共有13个种。本文从生物学、生态学及区系学的角度研究了这13个种的形态、食性及其分布特点,从此可以看出该类群发源于喜马拉雅地区并向该地区的东北、东南方向扩展。本研究对食植瓢虫亚科的演化增添了新的内容。

A STUDY ON THE SPECIES OF AFISSULA KAPUR 1955 AND THEIR GEOGRAPHICAL DISTRIBUTION

Afissula Kepur is a small genus of Epilachninae Epilachninae, established by A. P. Kapur in 1955. So far, 13 species have been recorded in the world. Except 2 species in Yunnan Province and 3 species in Sichuan Province, the rest 8 species are distributed in Xizang and the neighbouring countries of Himalayan region. From the distribution of 13 species of Afissula, most of the species are found in Xizang, Nepal., Sikkim, Northern India and Northeastern Burma, which may be assumed as the centerregion of original place. Some species of the genus are widely dispersing southeastward to Yunnan Province and northeastward to Sichuan Province.
