Vevers, 1922 is a genus of gastrointestinal spirurid nematodes parasitizing mainly felid but also canid, hyaenid and dasyurid hosts. Presently, 11 species are recognized worldwide, of which 4, , , and , have been recorded from African carnivores. In the present study, we describe n. sp. from hyaenas, namely (type host) in Zimbabwe and in Cameroon. The new species is the second species in the genus with bicuspid teeth. Furthermore, it can be distinguished from its congeners by a combination of characters, such as the absence of accessory teeth, the length and shape of the muscular oesophagus, position of the nerve ring, deirids and excretory pore in relation to the muscular oesophagus, the position of the vulva, spicule length and the shape of the female tail. Additionally, based on new material, detailed morphological descriptions are provided for and whose original descriptions were based on fragmented material. The material from , currently deposited as , is described as . First-time scanning electron micrographs are presented for the 4 species confirmed in African carnivores.
维弗斯 1922 年是一种寄生在主要是猫科动物身上的胃肠道旋尾线虫属，但也可以寄生在犬科、鬣狗科和袋鼬科宿主身上。目前，全世界已确认有 11 种，其中有 4 种， ， ， 和 ，已从非洲食肉动物中记录到。在本研究中，我们描述了来自鬣狗的新种，即 （模式宿主）在津巴布韦和 在喀麦隆。该新种是该属中的第二种具有双尖齿的物种。此外，它可以通过一系列特征与同属的其他种区分开来，例如没有副齿、肌肉食道的长度和形状、神经环的位置、与肌肉食道的关系、肛门的位置、肛刺的长度和雌性尾部的形状。此外，基于新材料，对 和 的形态学描述进行了详细说明，其原始描述是基于碎片材料。目前作为 保存的 材料被描述为 。首次呈现了在非洲食肉动物中确认的 4 种旋尾线虫的扫描电子显微镜照片。
