Abstract

Generic relationships within the parasitoid wasp subfamily Braconinae are assessed based on a molecular phylogenetic analysis of four gene fragments: mitochondrial cytochrome c oxidase subunit I, 16S rDNA, nuclear 28S D2-D3 rDNA and elongation factor 1-alpha. Our results support the recognition of Aphrastobraconini, Braconini and Coeloidini plus three new tribes: Compsobraconini tribus nov., Tropobraconini tribus nov. and Virgulibraconini tribus nov. The first of these new tribes is restricted to the New World; the second includes the Old World genera Tropobracon Cameron, Trispinaria Quicke and Grangerbracon Samartsev and Belokobylskij and possibly others, whereas the third comprises the Australian genus Virgulibracon Quicke, plus several other described and undescribed Australian genera. Consistent placement of Amyosoma Viereck with members of the Virgulibraconini tribus nov. is discussed, whereas Amyosoma is left currently unplaced. A preliminary key to tribes is presented, and the characters used to differentiate between Aphrastobraconini and Braconini are revised. Megacoeloides Quicke was never recovered with Coeloides, the type genus of Coeloidini, so it is treated as Braconinae incertae sedis. By combining molecular and morphological traits, nearly all valid genera are assigned to tribes, and the possible relationships of the remainder are discussed. Alienoclypeus Shenefelt, 1978 is synonymised with Atanycolus Förster, 1862 (Atanycolus insolitus (Shenefelt) comb. nov.). Several new genera have been revealed and will be described elsewhere.

腕足动物的系统发育（膜翅目：腕足动物）：A new tribal order！

基于线粒体细胞色素 c 氧化酶亚单位 I、16S rDNA、核 28S D2-D3 rDNA 和伸长因子 1-α 四个基因片段的分子系统学分析，评估了寄生蜂亚科 Braconinae 内的类属关系。我们的研究结果支持对 Aphrastobraconini、Braconini 和 Coeloidini 以及三个新支系的确认：Compsobraconini tribus nov.、Tropobraconini tribus nov.和 Virgulibraconini tribus nov.。其中第一个新支系仅限于新世界；第二个支系包括旧世界的 Tropobracon Cameron 属、Trispinaria Quicke 属和 Grangerbracon Samartsev 和 Belokobylskij 属，可能还有其它属；第三个支系包括澳大利亚的 Virgulibracon Quicke 属，以及其它几个已描述和未描述的澳大利亚属。讨论了 Amyosoma Viereck 与 Virgulibraconini tribus nov.成员的一致归属，而 Amyosoma 目前尚未归属。提出了一个初步的部落检索表，并修订了用于区分 Aphrastobraconini 和 Braconini 的特征。Megacoeloides Quicke从未与鳗鲡科的模式属Coeloides一起被发现，因此将其作为Braconinae的现生属处理。通过结合分子和形态特征，几乎所有有效属都被归入了部，并讨论了其余属的可能关系。Alienoclypeus Shenefelt, 1978 与 Atanycolus Förster, 1862（Atanycolus insolitus (Shenefelt) comb.）发现了几个新属，并将在其他地方进行描述。
