记述采自浙江的膜翅目三节叶蜂科平颜三节叶蜂属1新种:短顶平颜三节叶蜂Aprosthema brevivertexis Wei sp.nov..该种与同域分布的天目平颜三节叶蜂A.tianmunicum Wei& Wen,2000近似,但前翅翅痣下方具明显烟褐色横斑,1Rs显著长于2Rs室,Rs脉第2段1.3倍于Rs脉第3段长;单眼后区宽长比等于2.2,后部不高于单眼面;颚眼距稍窄于单眼直径;中胸背板前叶无中纵沟,具细纵脊;背面观锯鞘互相远离,侧面观锯鞘端部急尖等,与后者不同.“,”A new species of Sterictiphorinae of Argidae is described from Zhejiang,China:Aprosthema brevivertexis Wei sp.nov.This new species is similar to A.tianmunicum Wei & Wen,2000 from Zhejiang,but differs from it by the following characters:the fore wing with a broad smoky band below pterostigma,the cell 1Rs clearly longer than cell 2Rs,the second abscissa of the vein Rs 1.3 times as long as the third abscissa of Rs,the postocellar area weakly elevated and about 2.2 times as broad as long,the malar space clearly shorter than diameter of median ocellus,the mesoscutal middle lobe without middle furrow and with a fine middle carina,the lobes of the apical sheath in dorsal view far remote from each other,and in lateral view the apex of sheath strongly acuminated.

对新疆维吾尔自治区的蚱类昆虫物种多样性进行了修订和澄清.该地区共记录3种蚱:钻形蚱Tetrix subulata (Linnaeus,1758),隆背蚱Tetrix tartara (Saussure,1887)和土氏蚱Tetrix tuerki (Krauss,1876).同物异名修订如下:1)钻形蚱Tetrix subulata (Linnaeus,1758)=拟钻形蚱Tetrix subulatoides Zheng,Zhang,Yang&Wang,2006,syn.nov.;2)隆背蚱Tetrix
记述蚱属1新种:苍山蚱Tetrix cangshanensis sp.nov.,提供了新种的形态特征照片图.苍山蚱Tetrix cangshanensis sp.nov.与拟二斑蚱T.parabipunctata Zheng&Ou,2004和二斑蚱T.bipunctata(Linnaeus,1758)相似,但以直的颜面隆起,较高的触角着生位置和直的前胸背板前缘区别于后二者,同时以较短的后翅区别于拟二斑蚱;还以较狭的颜面隆起纵沟,向内收缩的沟前区侧隆线和波曲的中足股节下缘区别于二斑蚱.“,”One new

平须舞虻属Platypalpus Macquart是舞虻科中最大的属之一,已知550余种分布世界各地.四川以前已知8种.本文记述四川平须舞虻属3新种:短芒平须舞虻Platypalpus breviarista sp.nov.,微距平须舞虻Platypalpus minor sp.nov.和亚丁平须舞虻Platypalpus yadinganus sp.nov,均属于长角平须舞虻种团Platypalpus longicornis species group,并编制了四川平须舞虻属分种检索表.“,”Platy
大蚊属Tipula Linnaeus,1758是大蚊科中种类最多的属,目前其单系性尚未得到全面验证.此外,长角大蚊亚属Tipula (Sivatipula) Alexander,1964因其极长的触角以及独有的精子泵结构,明显不同于大蚊属其他亚属,使其亚属的分类地位存在争议.本研究基于COI序列对19个大蚊属物种及5个其他属物种进行了系统发育分析,并计算了物种间的遗传距离.研究结果表明:(1)邻接树(NJ)和最大似然树(ML)均显示长角大蚊亚属与大蚊属其他亚属未形成单系,大蚊属的单系性没有得到支持;(2)
对分布于北京的10种脊虎天牛属甲虫开展了分类研究,恢复了北京脊虎天牛Xylotrechus pekingensis Pic,1939的地位,不再是宽带脊虎天牛Xylotrechus yanoi Gressitt,1934的异名,报道了本种在河北和陕西的新分布记录.提出双带脊虎天牛Xylotrechus bifenestratus Pic,1916是四带脊虎天牛Xylotrechus polyzonus (Fairmaire,1888)的新异名,两者的模式标本均产自北京.本文还报道了3种北京新记录种:显纹脊
