摘要
球链蚧属Lecanodiaspis Targioni-Tozzetti 1869栎类群,系James O.Howell 和Michael Kosztarab 1972依据其形态和地理分布划分的4个类群之一。已知该类群现在全世界有14种,我国7种。这类蚧的雌成虫肛板外缘皆有网状或细胞状花纹;后气门路不分支;气门周缘通常有一高度硬化框,称之为“盒状”式气门。作者于1988年在云南省思茅地区采集蚧标本时,于石柯上采集到这一新种。新种的正模和副模标本,均保存于山东农业大学昆虫学教研室昆虫标本室。
A new species belonging to the Quercus group of the genus Lecanodiaspis collected rom Lithocarpus corneus in Simao Region,Yunnan Province,China is described.Lecanodiaspis lithocarpi Sun et Shi,sp.nov.Two sizes of bent 8-shaped pores present on dorsal surface.Larger pores in a marginalband and in some clusters on the dorsal surface.Smaller pores spread over remainder derm.Cribriform plates arranged in 4 longitudinal rows,each row composed of 3 plates.Antennae in terminal segment with 4 fleshy sensory setae and 3 slender setae.Two sizes of5-locular pores distributed in spiracular furrows,the ones near body margin larger,nearatrium smaller.This new species seems to be more closely related to L.tingtunensis(Borchsenius),but can be distinguished from it by the following characteristics:(1)antennae in terminal segment with 7 setae;(2)cribriform plates arranged in 4 longituinalrows.Holotype ♀,Paratype 4♀♀ were collected by Sun Jilin and Xue Ming on April 23,1988.Type specimens are kept in the Collection of the Department of Plant Protection,Shandong Agricultural University.
