The Afrotropical banchine fauna comprises 12 genera: Apophua Morley, Atropha Kriechbaumer, Cryptopimpla Taschenberg, Exetastes Gravenhorst, Glyptopimpla Morley, Himertosoma Schmiedeknecht, Lissonota Gravenhorst, Sjostedtiella Szépligeti, Spilopimpla Cameron, Syzeuctus Förster, Tetractenion Seyrig, and Tossinola Viktorov. A well-illustrated revised key to the genera using high definition images is provided, and the endemic Afrotropical genus Tetractenion is revised, previously represented by two described species. Four new species are described: T. ibayaensissp. nov., T. pascalisp. nov., T. pseudoluteasp. nov., and T. roseisp. nov. The first species-level identification key is provided for this rare genus. Based on morphological attributes the hypothesis is presented that the species in this genus are probably nocturnal. All images and online interactive Lucid keys are available at: www.waspweb.org and the associated underlying data is made available as Suppl. materials 1, 2 LIF3 files to this paper for inter-exchange with other key production software.

修订地方性非洲热带属 Tetractenion（膜翅目，Ichneumonidae），并为该地区提供 Banchinae 属的识别关键

Afrotropical banchine 动物群包括 12 个属：Apophua Morley、Atropha Kriechbaumer、Cryptopimpla Taschenberg、Exetastes Gravenhorst、Glyptopimpla Morley、Himertosoma Schmiedeknecht、Lissonota Gravenhorst、Sjostedtiella Szépligeti、Spilopimpla Cameron、Syzeuctus Förster、Tetractenion Seyrig 和 Tossinola Vik。提供了使用高清图像的该属的详细说明的修订密钥，并修订了地方性的非洲热带属 Tetractenion，以前由两个描述的物种代表。描述了四个新物种：T. ibayaensissp。十一月，T. pascalisp。11 月，T. pseudoluteasp。十一月，和 T.roseisp。十一月 为这个稀有属提供了第一个物种级别的识别密钥。基于形态属性，提出了该属的物种可能是夜间活动的假设。所有图像和在线交互式 Lucid 密钥均可在以下网址获得：www.waspweb.org，相关的基础数据作为增刊提供。资料 1、2 LIF3 文件到本文中，用于与其他关键制作软件的互通。
