本文报道姬蜂亚科Ichneumoninae,杂姬蜂族Joppini一新属,四新种。本新属与并区姬蜂属(Pterocormus Foerster,1850.)及裂缝姬蜂属(Chasmias Ashmead,1900.)相似,其主要区别是:本属并胸腹节第二侧区端横脊弯曲,唇基末端截形,无一宽弱齿,上颚顶端不窄,雄鞭节顶端不卷曲以及寄主等。模式标本保存在中国科学院昆明动物研究所。
In the present paper, a new genera and four new species of tribe Joppini, subfamily Ichne-umpninae are described as new from Lijiang and Deqin, Yunnan. A key to the species is provided in the Chinese text. All type specimens are deposited in the Kunming Institute of Zoology, Academia Sinica. 籋epialichneumon gen. nov.Black more yellow spots. Frons area with semicircular deep depression. Antennae fla-gellunes cylindric in the female and not serrate in the male. Apical margin of clypeus truncate, without a median tooth. Eyes large, long oval. Occipital carina joining hypostomal ca-rina above the base of mandible. Mesoscutum without notaulices. Propodeum slightly flat on basal half and then sloping, costula absent, its two lateral area have merged into one. Areo-la complete, nearly square. Spiraculs long. Wings hyaline, areolate sessile, pentagon. Nervel-lus curved towards inside. Petiole selencler, arch. Postpetiole with a weak median field, which is weakly striate. Abdomen without epiplearum, lanceolate, deprssed. Thyridia moderately large and distinctly impressed, the space between them larger than the width of a thy-ridia. Ovipositor sheath distinctly exserted beyond the dp of abdomen, as long as second tarsi of hind leg.Type species: Hepialichneumon yulcngensis Dong sp. nov.Closely allied to Pterocormus Foerster and Chasmias Ashmead, but differs from the two genera by the following characters: Apical transverse carina cuved; apical margin of clypeus truncate, without a broad median tooth; apical part of male flagellum not serrate and host. 1.
