摘要
Ekapagen mygalomorph蜘蛛的一个新属。nov.,描述自南非。新属的形成包括Hermacha curpipes Purcell,1902年和Hermacha nigra Tucker,1917年。这些物种基于它们的身体相似性而被同义,如中央凹形状、螯齿分布、眼睛模式、梳理梳的存在以及它们的紧密地理分布。提出的新属的区别在于雄性触诊胫骨后腹侧有一个突起,以及一个独特的交配球形状;雌性受精囊的形状决定,具有高基部和顶端茎,顶端茎通向椭圆形的顶端容器。
Ekapa, a new genus of mygalomorph spiders (Araneae, Entypesidae) from South Africa
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.
