Abstract:

A new species in the genus Aprostocetus is described in present paper:Aprostocetus magniventer Yang (Hymenopetra, Eulophidae:Tetrastichinae). It is an endo-parasitoid in the pupa of Fall Webworm, Hyphantria cunea (Drury) (Lepidoptera:Arctiidae), a serious invasive defoliator species to China. From one host, 45~62 adult wasps were reared out with proportion of female and male 2.6∶1, and parasitic ratio 3.5%. The species has good promising as a biological control agent for suppression of the pest. This unique species is quite different from all other species in the genus Aprostocetus by its great and sub-rounded gaster which is 1.5 times as wide as thorax. The type specimens of the new species are deposited in the Insect Museum of Chinese Academy of Forestry.
