NOTES ON CHINESE SPECIES OF THE GENUS ZAGLYPTUS FOERSTER,WITH DESCRIPTIONS OF A NEW SPECIES AND A NEW SPECIES-GROUP (HYMENOPTERA:ICHNEUMONIDAE)

雕姬蜂属Zaglyptus Foerster隶长尾姬蜂亚科Ephialtinae,瘤姬蜂族Pimplini。本属成虫特征前翅长3.0—9.0毫米;体稍长并细于大部分其他瘤姬蜂族的姬蜂;后头脊完整,中央不下弯;并胸腹节中等长,无中纵脊,在侧方亚端部有一个瘤状突起,此瘤在雌蜂非常突出而在雄蜂弱;无小翅室;后小脉通常在中央上方曲折;腹部第一节背板短宽,在中央正后方每边有一斜沟;第二节背板基侧角和后侧角有相当明显斜沟。

The present paper deals with seven species of the genus Zaglyptus Foerster collected from China. Among them, one species is new to science, four species marked with an asterisk*in the following list are recorded for the first time from China, and a new species-group is erected for the reception of a single species, Z. formosus Cushman. Formosus-group, group nov. The Formosus-group may be distinguished from all other groups of the genus by the combination of the following charactes, face black; notauli weakly im- pressed; submetapleural carina present only anteriorly as a blunt tooth; swellings on abdominal tergites punctate. Zaglyptus wuyiensis He, sp. nov. This species belongs to the Nigrolineata- group and resembles Z. nigrolineata Gupta, 1961 (Indian J. Ent.,22: 255) in the general sculpture and colour pattern on head and thorax, However, it differs from the latter in the following respects cheak 0.25 the basal width of the mandible; submetapleural carina present in the anterior 0.5 of the distance between middle and hind coxae; first tergite with a basal nib-like pentagonal black mark, the apex of which reaches the apical trans- verse band; second to fifth tergites each with a large basal triangular mark, the apex of which almost reaches the apical transverse band. Holotype:♀, Shi-ba-tiao, Mt. Wuyi, Fujian province, 1983.viii.3, HeJun-hua, No. 832554, deposited in the Laboratory of Biological Control, Zhejiang Agri- cultural University, Hangzhou.
