Abstract
A new genus of mygalomorph spider Ekapagen. nov., is described from South Africa. The new genus was formed to include the species Hermacha curvipes Purcell, 1902 and Hermacha nigra Tucker, 1917. These species are synonymized based on their somatic similarities, such as fovea shape, cheliceral teeth distribution, ocular pattern, presence of preening combs, and their close geographic distribution. The new genus proposed is distinguished by the presence of a projection in the retroventral side of the palpal tibia in males, together with a distinctive copulatory bulb shape; and in females by the shape of their spermathecae, with a high base and apical stalks that open into oval apical receptacles.
期刊介绍：
African Invertebrates is an international peer-reviewed, open-access journal that focuses primarily on the taxonomy, systematics, biogeography, and palaeontology of Afrotropical invertebrates, whether terrestrial, freshwater or marine. Aspects concerning biology, ecology, and conservation may also be considered where these relate to the primary focus areas. Papers dealing solely with biology, ecology, physiology, pests and pest control should be submitted elsewhere.
