摘要: 记述采自中国内蒙古和宁夏贺兰山危害青海云杉的扁蜂科一新种:烟翅腮扁蜂Cephalcia infumata Zhang&Wei,sp.nov.。本种与贺兰腮扁蜂Cephalcia alashanica(Gussakovskij,1935)和马氏腮扁蜂C.masuttii Battisti&Boato,1998近似,3种扁蜂的幼虫均在云杉嫩枝上用虫粪做成显著的虫巢。烟翅腮扁蜂与贺兰腮扁蜂的区别:翅深烟褐色;雌虫各足股节背侧部分淡色,腹侧大部黑色;雌虫后眶中下部无后颊脊;两性触角第3节长于第4+5节之和,长于复眼长径;雄虫阳茎瓣内顶角近方形等。烟翅腮扁蜂与马氏腮扁蜂的区别:翅深烟褐色;中胸背板侧叶全部和后小盾片、雄虫小盾片、两性腹部1-6背板大部、雌虫各足股节腹侧大部黑色;两性触角窝侧区的上侧3/5具刺毛和粗大刻点,下侧2/5无刺毛、无刻点;触角通常26节;雄虫阳茎瓣无臀角等。烟翅腮扁蜂与贺兰腮扁蜂COⅠ序列的K2P距离为5.2%。

Abstract: Cephalcia infumata Zhang & Wei, sp. nov., a new species of Pamphiliidae (Hymenoptera) defoliating Picea crassifolia Kom.was collected from Helanshan Mountains, Inner Mongolia, China. The new species is similar to Cephalcia alashanica and C. masuttii. The larvae of the three species make conspicuous nests with silk and dung on the twigs. The new species differs from Cephalcia alashanica by the characters as follows:1) wings in both sexes deeply infuscate; each femur largely black on ventral side and largely pale brown on dorsal side; 2) the middle and lower parts of hind orbit without occipital carina; 3) the antennomere 3 clearly longer than the sum of antennomeres 4 and 5 together, and longer than the longest axis of eye as well; 4) the inner apical corner of valviceps aubquadrate. The new species differs from Cephalcia masuttii as follows:1) wings in both sexes deeply infuscate; 2) the mesoscutal lateral lobes and metascutellum in both sexes, male mesoscutellum, the ventral side of each femur and the abdominal tergites 1-6 in both sexes largely black; 3) the ventral 2/5 of paraantennal area naked and smooth; 4) antenna with about 26 antennomeres; 5) the valviceps without distinct anal corner. The K2P distance between the COⅠ of Cephalcia infumata and C. alashanica is 5.2%.
