摘要
A new species,Sclerodermus alternatusi Yang,sp.nov.(Hymenoptera:Bethylidae),is described and illustrated.Its cerambycid host,Monochamus alternatus Hope,a severe wood borer attacking many pine trees(Pinus spp.),is also a vector of pine wood nematode,Bursaphelencus xylophilus,which cause severe damages to pine forests in China.The new species is a gregarious ectoparasitoid of junior larva of M.alternatus.The number of adult wasps reared from a single host larva ranges from 6 to 45.The ratio of female to male is 20:1.The new parasitoid species has a high potential in using as a biocontrol agent for the wood borer.Diagnosis of the new species with comparisons to its related species,S.pupariae Yang&Yao and a key to known species of Sclerodermus from China is provided.
