异胫长小蠹属中国记录种

Species record of Chinese Crossotarsus

我国2007年修订公布的《中华人民共和国进境植物检疫性有害生物名录》将异胫长小蠹属非中国种作为我国进境植物检疫性有害生物。因此开展该类群中国记录种的厘订工作具有重要意义。本文记述了异胫长小蠹属中国记录种13种,即针叶异胫长小蠹Crossotarsus coniferae、缺刻异胫长小蠹C.emancipatus、外齿异胫长小蠹C.externedentatus、壳斗异胫长小蠹C.fagacearum.、黄翅长小蠹C.flavomaculotus、端刺异胫长小蠹C.impariporus,日本异胫长小蠹C.niponicus、黑异胫长小蠹C.piceus、台湾异胫长小蠹C.sauteri、简长小蠹C.simplex、鳞异胫长小蠹C.squamulatus、端异胫长小蠹C.terminatus和华氏异胫长小蠹C.wallacei,对这些种类的主要形态特征进行了描述,并编制了种类检索表。同时整理出了这些种类的寄主及分布。

Crossotarsus(non -Chinese species ) were listed in Chinese pest for imported platnts revised and announced in 2007,so it is very important to work out the species.Thirteen species recorded of Chinese Crossotarsus are described in this paper.They are Crossotarsus coniferae,C.emancipatus,C.externedentatus,C.fagacearum,C.flavomaculatus,C.impariporus,C.niponicus,C.piceus, C.sauteri,C.simplex,C.squamulatus,C.terminatus and C.wallacei.Otherwise,a key to species from China,their geographical distribution and host plants are also dealt with.
