A new ant-like spider species of the subfamily Castianeirinae, Mazax akephaloi sp. nov., representing the second species of Mazax recorded from South America, is described from the Bolivian orocline and the Paraguayan Chaco region. The new species superficially resembles Mazax ramirezi Rubio Daniman, 2014, but can be distinguished from this species and all other congeners by a combination of the following characters: feathery setae on the carapace, a tibia I spine formula of 54 in males and 55 in females, the embolus sub-apical with a spatulate extension, the lung-shaped spermathecae II and slightly undulating copulatory ducts. Adults of M. akephaloi sp. nov. were observed foraging in association with workers of the ant Ectatomma permagnum Forel, 1908 on the ground or leaf litter along forest edges. Although the spiders were lacking a structure imitating the head of the ants, they shared several characters (dark brown integument with distinct, coarse wrinkles and shiny reflections, abdomen anteriorly with dorsally pointing process and distinct median constriction) that increased the species-specific similarity to their potential ant models.
一种新的拟蚁蜘蛛——卡氏拟蚁亚科 Mazax akephaloi sp. nov.，代表了从南美洲记录到的第二个 Mazax 物种，来自玻利维亚的造山带和巴拉圭查科地区。新种在外表上类似于 Mazax ramirezi Rubio Daniman, 2014，但可以通过以下特征组合与该物种和所有其他近缘种区分开来：甲壳上的羽状刚毛、雄性胫节 I 刺的 54 个公式和雌性的 55 个公式、触肢器亚顶端带有片状延伸的弯钩、肺形的精囊 II 和略微起伏的交配管。M. akephaloi sp. nov. 的成虫被观察到与蚂蚁 Ectatomma permagnum Forel, 1908 的工蚁一起在森林边缘的地面或落叶层中觅食。尽管这些蜘蛛没有模仿蚂蚁头部的结构，但它们具有几个特征（深棕色的外骨骼，有明显的粗糙皱纹和闪亮的反射，腹部前部有指向背部的突起和明显的中央收缩），这增加了它们与潜在的蚂蚁模型的物种特异性相似性。
