Abstract

Abstract:

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.

Key words: sawfly, taxonomy, Picea crassifolia, Qinghai Province
