Three new species of the Afrotropical braconine wasp genus Bacuma are described, and biological observations (nectar feeding) by one of them are noted. The new species are: B. kayserae Quicke & Butcher sp. nov. from Kenya, B. madiensis Quicke & Butcher sp. nov. from Uganda and B. darfurensis Quicke & Butcher sp. nov. from Sudan. A group of four large nominal species with red metasomas and finely sculptured tergites (B. granulatus, B. maculipennis, B. rufa and B. whitei) may represent a single widespread species or a pair of species separated by mesoscutum colour, or four separate but morphologically very similar species. However, given the small number of specimens available for study and the poor condition of some of these, including the types, they are not formally synonymised here. A partial key to the species of Bacuma is presented, which recognizes those species that are clearly distinct, including three new species. Interactive Lucid dichotomous and matrix keys are available on www.waspweb.org.
描述了非洲热带地区茧蜂亚科黄蜂属Bacuma的三个新物种，并记录了其中一种的生物学观察情况（取食花蜜）。新物种分别是：来自肯尼亚的凯氏巴库茧蜂B. kayserae Quicke & Butcher sp. nov.、来自乌干达的马迪巴库茧蜂B. madiensis Quicke & Butcher sp. nov.以及来自苏丹的达尔富尔巴库茧蜂B. darfurensis Quicke & Butcher sp. nov.。一组有红色后体和具精细刻纹背板的四个大型指名物种（颗粒巴库茧蜂B. granulatus、斑翅巴库茧蜂B. maculipennis、红巴库茧蜂B. rufa和怀特巴库茧蜂B. whitei）可能代表一个分布广泛的单一物种，或者是由中胸盾片颜色分隔的一对物种，又或者是四个独立但形态非常相似的物种。然而，鉴于可供研究的标本数量较少，且其中一些标本（包括模式标本）状况不佳，在此并未对它们进行正式的同物异名处理。给出了一个巴库茧蜂属物种的分种检索表，该检索表识别出了那些明显不同以及包括三个新物种在内的物种。可在www.waspweb.org上获取交互式的Lucid二歧分类检索表和矩阵检索表。
