摘　　要：记述采自中国青海危害青海云杉的松叶蜂科新松叶蜂属一新种:青海新松叶蜂Neodiprion qinghaiicus Wei,Wang&Wu,sp.nov.。本种的锯腹片和阳茎瓣与青杄新松叶蜂很相近,主要形态区别有:触角黄色,栉齿黑色,鞭节Ⅰ—Ⅱ腹缘在侧面观等长(青杄新松叶蜂触角黑色,鞭节Ⅱ腹缘在侧面观略长于鞭节Ⅰ);后翅1 M室腹缘被cu-a截断的部分,内侧长于外侧(青杄新松叶蜂中这2部分翅脉长度相等);虫体瘦削(青杄新松叶蜂虫体粗壮)。体色与同属成员差别较大,可通过头部黑色且腹部黄色无黑斑等特征与中国其他新松叶蜂相区分。提供了中国新松叶蜂属分种检索表。In the present paper,a new species of Diprionidae,Neodiprion qinghaiicus Wei,Wang&Wu,sp.nov.,damages needles of Picea crassifolia from Qinghai Province,China.This species is very similar in the lancet and penis valve to N.wilsonae(Li&Guo,1999)but differs from the latter by the following characters:antenna yellow with black flagellar dents and ventral length of first and second flagellomeres equal in length(versus N.wilsonae antenna entirely black,ventral length of second flagellomere longer than ventral length of first flagellomere);In hind wing,length of inner part of cell 1 M basad vein cu-a is clearly longer than outer part of cell 1 M beyond vein cu-a(the two parts equal in N.wilsonae);The body of the insect is narrower(body robust in N.wilsonae).The new species can be recognized from its congeners by the black head and yellow abdomen.A key to Chinese Neodiprion species is provided.
