【Abstract】 The present paper describes five species of sawflies of the genusDiprion from China.Of which four are new to science and one is recordedfor the first time in China.All the type-specimens are preserved in theinsect collection of the Division of Forest Entomology,Forest ResearchInstitute,Chinese Academy of Forestry. 1. Diprion Liuwanensis Huang et Xiao sp.nov. The new species is closely related to Diprion hutaoharernae Smith;butit differs from the latter in the following points:Apical portion behindpterostigma of fore wing of female infuscated;lancet longer,with 11 annuli; ventral lobes 2—6 rather deeply emarginated,7—11 truncated;scopal padshorter,not in the shape of sausages. 2. Diprion wenshanicus Xiao et Zhou sp.nov. The new species is close to Diprion hutacharernae Smith;but itdistinguished from the latter by lancet with 11 annuli;teeth on annulismaller;ventral lobe 2 with its hind angle projecting as a mammilla;annuli 3—5 slightly emarginated,scopal pads storter.not sausage-shaped. 3. Diprion tianmunicus Zhou et Huang sp.nov. Body elongate,lancet narrower and longer,distance between annuli 1and 2 particularly widened,annuli 3 and 4 divergent dorsally,ventral lobe2 rather deeply emarginated,scopal pads long oval in shape.By theconbination of all above characters the new species may be separated fromDiprion similis (Hartig) and from Diprion hutacharernae Smith. 4. Diprion nanhuaensis Xiao sp.nov. The new species is very similar to Diprion hutacharernae Smith,withthe following principal exceptions:in the female,most clypeus,supraclypealarea,most mesoscutellum,and metascutellum black;lancet with ventrallobes 2—5 imarginated;scopal pads shorter,not in the shape of sausages;in the male,labrum yellowish brown;abdominal tergite 1 with only medianportion punctured;penis valve with apex slightly flat and with ventral sideemarginated not as deep as that of Diprion hutacharernae Smith.更多还原
