Five new species belonging to Dirhinus Dalman are described: D. quadrhinus Delvare sp. nov., D. gigasetosus Delvare sp. nov., D. kambae Delvare sp. nov., D. maasaii Delvare sp. nov. and D. leakeyorum Delvare sp. nov. These species belong to the newly defined and characterized quadrhinus species group, included in the subgenus Dirhinus of Dirhinus Dalman. Evidence for this taxonomic placement is provided despite the distinctive morphology exhibited by the relevant species. The himalayanus, claviger, anthracia and hesperidum groups, also included in subgenus Dirhinus, are similarly defined and characterized and lists of the relevant described species are provided. A key to the females of the quadrhinus group is given. The phylogeny of the genus Dirhinus, especially the other subgenera Pareniaca and Hontalia is discussed as well as the morphological characters the genus Dirhinus in relation to the potential hosts, and the restricted distribution of the members of the quadrhinus group in Kenya.
描述了属于达尔曼氏金小蜂属（Dirhinus Dalman）的五个新物种：四方达尔曼氏金小蜂（D. quadrhinus Delvare sp. nov.）、多刚毛达尔曼氏金小蜂（D. gigasetosus Delvare sp. nov.）、坎巴达尔曼氏金小蜂（D. kambae Delvare sp. nov.）、马萨伊达尔曼氏金小蜂（D. maasaii Delvare sp. nov.）和利基氏达尔曼氏金小蜂（D. leakeyorum Delvare sp. nov.）。这些物种属于新定义和特征化的四方金小蜂物种组，包含在达尔曼氏金小蜂属（Dirhinus Dalman）的金小蜂亚属（Dirhinus）中。尽管相关物种表现出独特的形态，但仍提供了这种分类地位的证据。同样包含在金小蜂亚属中的喜马拉雅金小蜂组、棒角金小蜂组、炭疽金小蜂组和柑橘金小蜂组也进行了类似的定义和特征描述，并提供了相关已描述物种的列表。给出了四方金小蜂组雌性的检索表。讨论了达尔曼氏金小蜂属的系统发育，特别是其他亚属帕雷尼亚卡（Pareniaca）和洪塔利亚（Hontalia），以及达尔曼氏金小蜂属与潜在宿主相关的形态特征，以及四方金小蜂组成员在肯尼亚的有限分布。
