was identified morphologically, using body annuli number (103105), stylet length (49-52 μm), tail conical with small rounded lobe, spermatheca with round sperm, and VL/VB (1.3). Molecular analysis was also undertaken, based on the 18S rDNA region, and the obtained DNA sequence data confirmed the present population from South Africa as . Phylogenetic analysis using the Bayesian inference method places this population close to from China (MH444620-21; MH444626-28). To the best of our knowledge, this is the first report of the 18S rDNA sequence for .
通过形态学鉴定，依据体环数（103 - 105）、口针长度（49 - 52μm）、尾部呈圆锥形且有小圆形叶、受精囊中有圆形精子以及VL/VB（1.3）。还基于18S rDNA区域进行了分子分析，所获得的DNA序列数据证实来自南非的当前种群为[具体物种名称未给出]。使用贝叶斯推断方法进行的系统发育分析将该种群置于与来自中国的[具体物种名称未给出]（MH444620 - 21；MH444626 - 28）相近的位置。据我们所知，这是关于[具体物种名称未给出]的18S rDNA序列的首次报道。
