【摘要】 本文在总结前人工作的基础上,对我国蒙新区网蝽科昆虫进行了分类学修订及研究,主要涉及了蒙新区网蝽科昆虫的种类、形态特征、分布、寄主、区系分析以及部分种类的外生殖器的比较解剖。研究表明,中国蒙新区已发现网蝽59种,隶属于1亚科(网蝽亚科Tinginae)18属,其中包括1个新种(黑跗小网蝽Agramma nigrytarsus sp. nov.)5个中国新纪录种(侧脊小网蝽Agramma atricapillum (Spinola,1837))、丝小网蝽Agramma turanicum (Horváth,1905)、窄无孔网蝽Dictyla minuta Golub,1976、蒙无孔网蝽Dictyla subdola (Horváth, 1905)、广布裸菊网蝽Tingis (s.str.) cardui (Linnaeus, 1758)),并对原记载作出2处修订,丝小网蝽Agramma turanicum (Horváth, 1905)=Agramma blandulum (Horváth, 1905) (Misidentification by Qi),广翅裸菊网蝽Tingis (s. str. ) lasiocera Matsumura, 1907=Tingis (s. str.) cardui Jing, 1981;解除Leptoypha St?l, 1873与Tingis (Birgitta) Lindberg, 1927的异名关系,并将作为Tingis的亚属之一的Birgitta Lindberg, 1927提升为属级阶元;重新对暗贝脊网蝽Galeatus affinis (Herrich-Schaefer, 1835)的分类地位进行了讨论,认为该种与菊贝脊网蝽Galeatus spinifrons (Fallen, 1807)不同,其分类阶元成立。文中也对分类学中存在的争议问题进行了讨论,并附了属种检索表及个别种的形态特征图、外生殖器解剖图以及照片;从区系结构看,蒙新区网蝽科昆虫在属级阶元上以古北界和东洋界的共有属和仅分布于古北界的属占优势,各占总数的16.67%;在种级阶元上,主要归属于古北界;仅分布于古北界的种类有46种,占总数的77.97%,其余为古北界与其它各界分布的共有种,占总数的22.03%。蒙新区网蝽科昆虫以蒙新区种类占绝对优势,所占比重高达64.41%,其它种类在我国的东北区、华北区、青藏区、华中区、华南区、西南区也分别有分布,占总数的35.59%。更多还原

【Abstract】 In the paper, 59 species of Tingidae, belonging to 18 genera from Mongolia-Xinjiang Region of China were recorded. Among them, 1 new species Agramma nigrytarsus sp. nov., 5 Chinese new record species, Agramma atricapillum (Spinola,1837), Agramma turanicum (Horváth, 1905), Dictyla minuta Golub, 1976, Dictyla subdola (Horváth, 1905) and Tingis (s.str.) cardui (Linnaeus) were described and 2 species of original record were revised. The classified position of Galeatus affinis (Herrich-Schaefer, 1835) was discussed and considered as a good species. The faunistic analysis of Tingidae from Mongolia-Xinjiang Region displayed that the Palaeartic species occupy 77.97%. The species only belonging to Mongolia-Xinjiang Region is dominant, which occupy 64.41%. Distribution, morphology, dissect and compare of genitalia of some species of Tingidae were provided.更多还原
