摘要
描述灰翅麦茎蜂(Cephus fumipennis Ev.)(膜翅目:茎蜂科)的形态。其成虫体柔弱、柱状、黑色,具金属光泽,被灰棕色绒毛,长8～11mm,腹部、足和前翅具黄斑或黄带;幼虫具独特的肛上突,其顶面和侧面光滑。比较灰翅麦茎蜂和另外3种麦茎蜂(C.pygmaeus,C.cinctus,C.tabidus)的形态,指出4种成虫和幼虫的主要相似性和差别集中于成虫色素沉积、马蹄形压痕、产卵器鞘和幼虫第8～10腹节背板及肛上突。
The morphology of Cephus fumipennis Eversmann（Hymenoptera： Cephidae） was described.Adults are overall slender,cylindrical,and black,with a metallic luster,covered with grayish brown villi,and 8-11 mm long.The abdomen,legs and forewings bear yellow spots or bands.The larva has a distinct suranal process with its top and lateral surfaces glabrous.C.fumipennis was compared with the other three cephids,C.pygmaeus,C.cinctus,and C.tabidus,and major similarities and differences were given,focusing on body pigmentations,horseshoe-shaped depressions and vaginula for adult,and on abdominal tergites VIII,IX and X,and suranal process for larva.
