额凹萤叶甲属 Sermyloides 属鞘翅目(Coleoptera)叶甲科(Chrysomelidae)、萤叶甲亚科(Galerucinae)。它以头部额唇基区凹陷、其中有一些隆起为属的主要特征,是典型的东洋区分布属。目前本属世界已知21种,主要分布于东南亚及我国南方,本文又增 相似文献

半蓝角伪叶甲Cerogria basalis(Hope,1831)为角伪叶甲属Cerogria Borchmann,1909的1个大型种,过去仅知道分布于印度,尼泊尔,波斯尼亚和黑塞哥维那,一直缺乏详细和正式的形态描述。近年来,我们从云南采集到该种的雌虫和雄虫。本文对该种雌性和雄性成虫,特别是触角、腹板和雄性外生殖器特征作了详细描述。提供了该种雌、雄两性成虫的背面观和腹面观以及生境照片,以及触角、雄性末节腹板以及雄性外生殖器特征图片。本文还讨论了种内变异。这些工作为该种的正确鉴定提供了依据。 相似文献

伪叶甲科Lagriidae是鞘翅目的一个小科,全世界已知约2450种。过去有17位外国学者零星地记述了我国该科昆虫22属和124种6变种。1991年以来作者系统地研究了该科的分类、雄性外生殖器形态结构、系统发育和地理分布。本文报道莫伪叶甲属Merklia力和粗伪叶甲属Pachystira二个新属,及两斑莫伪叶甲Merkliabimaculata和凹翅粗伪叶甲Pachystiraimpressipennis二个新种。 相似文献

Replacement of two to four guanines by adenines in the human telomere DNA repeat dG3(TTAG3)3 did not hinder the formation of quadruplexes if the substitutions took place in the terminal tetrad bridged by the diagonal loop of the intramolecular antiparallel three‐tetrad scaffold, as proved by CD and PAGE in both Na+ and K+ solutions. Thermodynamic data showed that, in Na+ solution, the dG3(TTAG3)3 quadruplex was destabilized, the least by the two G:A:G:A tetrads, the most by the G:G:A:A tetrad in which the adenosines replaced syn‐guanosines. In physiological K+ solution, the highest destabilization was caused by the 4A tetrad. In K+, only the unmodified dG3(TTAG3)3 quadruplex rearranged into a K+‐dependent quadruplex form, none of the multiple adenine‐modified structures did so. This may imply biological consequences for nonrepaired A‐for‐G mutations. © 2010 Wiley Periodicals, Inc. Biopolymers 93: 880–886, 2010. 相似文献
