我国三种蛛甲记述及仓储物蛛甲检索表

NOTES ON THREE SPECIES OF PTINIDAE WITH A KEY TO THE MEMBERS OF THE FAMILY ASSOCIATED WITH STORED PRODUCTS IN CHINA

本文记述了国内仓储物内发现的3种蛛甲,即四纹蛛甲Ptinus villigerReitter、沟胸蛛甲P. sulcithorax Pic和棕蛛甲P. clavipes Panzer;对过去国内文献中记述的粗足蛛甲(仓储蛛甲)Tipnus unicolor Pill. et Mitt.和窃蛛甲Ptinus latro F.进行了讨论,认为粗足蛛甲可能属于误定,而窃蛛甲实为棕蛛甲.最后列出国内8种蛛甲检索表,其中包括作者1986年记述的拟裸蛛甲Ptinus aequinoctiale Boieldieu(过去国内文献中误定为裸蛛甲P. psylloides Czemp.)和短毛蛛甲P. sexpunctatus Panzer.

The paper presents three species of ptinidae found in china, they are Ptinus villiger Reitter, P. sulcithorax Pic and P. clavipes Panzer.Tipnus unicolor Pill. et Mitt and Ptinus latro Fabricius listed in past chinese literatures are also discussed. The authers consider that Ptinus sulcithorax Pic may be wrongly identified as Tipnus uniicolor Pill. et Mitt. and Ptinus latro F. actually is Ptinus clavipes Panzer.Finally, a key to eight injurious species is provided, including Ptinus aequinoctiale Boieldieu (wrongly identified as P. psylloides Czemp.) and P. sexpunctatus Panzer noted by authers in 1986.
