长革扁蝽属Dolichothyreus是Usinger & Matsuda 1959年根据采自加里曼丹的1头雌虫建立的。此前中国尚未有此属的报道。我们研究海南的扁蝽标本时,发现此属模式种的雄虫。本文对该属进行重新描述,并记述了该属模式种痣长革扁蝽D. stigmatus Usinger & Matsuda的雄性。该属主要特征为:体小,长卵圆形。全翅。棕红至棕黑色。体被颗粒。头前叶短钝;颊伸达前叶端部;触角短粗。前胸背板前叶中央具倒"Y"型脊突。前翅膜片完整,具翅脉。第3腹背板中央具细脊包围的宽浅凹域。  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
