中国锯天牛亚科区系研究(鞘翅目 天牛科)

Fauna Analysis of Prioninae in China(Coleoptera:Cerambycidae)

截止2009年,我国已记载锯天牛亚科6族、22属、103(亚)种.通过区系分析得出:在属的组成中,若按区系成分分析,北方区系成分3属,南方区系成分17属和南北区系成分不明的2属;属的比例各为13.64%,77.27%和9.09%.在种的组成中,北方区系成分17(亚)种,占总区系成分的16.50%;南方区系成分77(亚)种,占总区系成分的74.76%;南北区系特征不明的7种,占总区系成分的6.80%;全国分布的2种,占总区系成分的1.94%.该亚科属、种的分布均以南方区系成分占优势,并存在中国特有的区系成分.

Up to now,6 tribes,22 genera and 103 species of Prioninae have been recorded in China.Three and 17 genera belong to the Northern and the Southern faunal parts,respectively,while the remaining 2 genera are unidentified about their positions,accounting for 13.64%,77.27% and 9.09% of the total.This is also true of the composition of the species：17 species and subspecies belong to the Northern faunal part,accounting for 16.50% of the total;77 species and subspecies belong to the Southern faunal part,accounting for 74.76% of the total;and the remainder are non-identified,accounting for 6.80% of the total.The components of the Oriental Region are predominant as compared with those of the Palearctic Region.The fauna of Prioninae and the unique species of each region in China are discussed.
