Abstract

A new genus of the spider family Trachelidae L. Koch, 1872 from the Afrotropical Region is described. Capobula gen. nov. is represented by five species, known from South Africa and Lesotho only. Adults of both sexes of Orthobula infima Simon, 1896a, which is widely distributed in the Western Cape, South Africa, are described for the first time, and this species is transferred to Capobula gen. nov. as its type species. Four new species are described: C. capensis spec. nov. and C. neethlingi spec. nov. (South Africa: Western Cape), C. montana spec. nov. (Lesotho and South Africa: Eastern Cape, Free State and KwaZulu-Natal) and C. ukhahlamba spec. nov. (South Africa: KwaZulu-Natal). A phylogenetic analysis based on the cytochrome oxidase subunit I (COI) gene, including 14 genera of Trachelidae, one genus of Clubionidae Wagner, 1887 and three genera of Phrurolithidae Banks, 1892, supports the placement of Capobula gen. nov. in Trachelidae, with Orthobula Simon, 1897 as its likely closest relative.

摘要

描述了来自非洲热带地区的 Trachelidae L. Koch, 1872 科的一个新蜘蛛属。Capobula 属由仅分布在南非和莱索托的 5 个物种组成。广泛分布在南非西开普省的 Orthobula infima Simon, 1896a 的雌雄成体首次被描述，并将该物种转移到 Capobula 属作为其模式种。描述了四个新物种：C. capensis spec. nov. 和 C. neethlingi spec. nov.（南非：西开普省）、C. montana spec. nov.（莱索托和南非：东开普省、自由州和夸祖鲁-纳塔尔省）和 C. ukhahlamba spec. nov.（南非：夸祖鲁-纳塔尔省）。基于细胞色素氧化酶亚基 I（COI）基因的系统发育分析，包括 Trachelidae 的 14 个属、Clubionidae Wagner, 1887 的 1 个属和 Phrurolithidae Banks, 1892 的 3 个属，支持将 Capobula 属归入 Trachelidae，其中 Orthobula Simon, 1897 可能是其最接近的亲缘关系。
