蒙古高原花天牛亚科昆虫区系的初步分析

对已记载的蒙古高原花天牛亚科昆虫26属63种昆虫的种类组成及区系进行初步分析。各属所包含的天牛种类数量差异很大,以缘花天牛属(Anoplodera)为优势属,花天牛属(Leptura)次之,且在俄、蒙、中3国,各属的种类组成既相似又有差异;区系分析表明,蒙古高原花天牛亚科昆虫以古北界种类占绝对优势,仅分布于古北界的种类有49种,占蒙古高原花天牛科昆虫总数的74.60%;在中国无分布记录的蒙古高原花天牛亚科昆虫有4种,分别是长毛眼花天牛(Acmaeops anthracina Mannerheim)、红柄短胸花天牛[Alosterna tabacicolor(De Geer)]、长缘花天牛[Anoplodera longipes(Gebler)]、东北伪花天牛(Leptura renardi Gebler)。

Species Composition and Faunal Analysis of Lepturinae in Mongolian Plateau (Coleoptera: Cerambycidae)
