Abstract

The continental Afrotropical species of the spider genus Orthobula Simon, 1897 are revised. The three currently known species, O. calceata Simon, 1897 (West Africa and western Congo Basin), O. milloti Caporiacco, 1949 (Kenya) and O. radiata Simon, 1897 (southern Africa), are redescribed, including the first descriptions of the males of O. calceata and females of O. radiata. Three new species are described from both sexes: O. aethiopica sp. nov. from Ethiopia, O. arca sp. nov. from South Africa, and O. marusiki sp. nov. from West Africa and the western Congo Basin. All of the species are obligate ground-dwellers, being particularly common in the leaf litter of woody plants, except for O. arca sp. nov., which prefers open grasslands.

摘要

修订了大陆非洲热带地区的蜘蛛属 Orthobula Simon, 1897 种。目前已知的三个物种，O. calceata Simon, 1897（西非和刚果盆地西部）、O. milloti Caporiacco, 1949（肯尼亚）和 O. radiata Simon, 1897（南部非洲），进行了重新描述，包括 O. calceata 雄蛛和 O. radiata 雌蛛的首次描述。从两性中描述了三个新物种：来自埃塞俄比亚的 O. aethiopica sp. nov.、来自南非的 O. arca sp. nov. 和来自西非和刚果盆地西部的 O. marusiki sp. nov.。所有这些物种都是专性地面生物，特别是在木本植物的落叶层中非常常见，除了 O. arca sp. nov.，它更喜欢开阔的草原。
