| 中文摘要:尖唇叶蜂属Adamas Malaise是中国新记录属。本文记述1个中国新记录种：宽缘尖唇叶蜂Adamas jakowleffi(Konow，1897)和4个新种：黄尾尖唇叶蜂A.caudatus sp.nov.，平行尖唇叶蜂A.parallelus sp.nov.，徐氏尖唇叶蜂A.xuisp.nov.和吕氏尖唇叶蜂A.lui sp.nov.，给出了详细描述和形态特征图，并编制了分种检索表。详细讨论了尖唇叶蜂属的系统学地位，初步分析了6个已知种之间的关系，认为A.jakowleffi(Konow)和A.ermak Zhelochovtsev,A.caudatus和A.parallelus.A.xui和A.lui分别构成一对姊妹种关系。尖唇叶蜂属上颚不对称，左上颚具1个大型基齿，右上颚单齿，唇基缺口深，侧叶尖，前翅臀室具很短的倾斜横脉，前胸侧板腹侧接触面窄或无，后胸后背板中央甚狭，后足基跗节很短等，表明本属是平背叶蜂亚科成员，系统学地位介于Allantini族和Empriini族之间，并自成一族——尖唇叶蜂族Adamasini。 |

| Abstract:The genus Adamas Malaise is firstly recorded from China. Four species are described as new to science: A. caudatus sp. nov., A. parallelus sp. nov., A. xui sp. nov. and A. lui sp. nov. Adamas jakowleffi (Konow, 1897) is also firstly recoded from China. Each species are described in detail and figured. A key to species of the genus is provided. The systematic position of Adamas Malaise and the relationships between the 5 species of the genus are discussed. Adamas is undoubtedly a member of the Allantinae as shown in the character combination: the mandibles asymmetrical, left mandible with a long apical tooth and a large basal tooth, right mandible simple; the clypeus broadly and deeply incised with narrow lateral lobes; the anal cell of fore wings with a short cross vein at the apical 2/5, and the vein R straight. The propleura acute and hardly meeting ventrally, the metapostnotum very narrow and contracted on meson, the hind basitarsi quite short and the tarsal claws simple, these suggest that the genus Adamas has relation to Empriini. However, the anal cross vein in fore wings basad of the vein 1M, the peculiar clypeus, the long R+M and the asymmetrical mandibles take it apart from the tribe Empriini and support it to be a separate tribe Adamasini (= Adamini Wei et Nie, 1998). A. jakowleffi (Konow) and A. ermak Zhelochovtsev, A. caudatus and A. parallelus, A. xui and A. lui are sister species separately. Type specimens are deposited in the Insect Collection of Central South Forestry University, Zhuzhou, China (CSFU). |
