n. sp. is described and illustrated from the West Azerbayjan province, northwestern Iran. The new species is characterized by its body length of 807 to 963 μm (males) and 792 to 1,094 μm (females), offset cephalic region, lateral fields with four incisures, long stylet with 15 to 16 μm length, and excretory pore situated opposite or behind the nerve ring. Pharyngeal glands overlapping intestine dorsally and extending for 90 to 121 μm, tail terminus mucronate in both sexes. Vagina directed anteriad, and spicules are relatively large (27-32 μm) with well-developed broadly rounded apex and condylus. The new species comes close to seven known species of the genus namely , , , , , , and , but it differs from them by the body size, stylet length, size of spicules, and length of postvulval uterine sac. The results of phylogenetic analyses based on sequences of D2-D3 expansion region of 28S and 18S rDNA, confirmed its status as a new species.
在伊朗西北部的西阿塞拜疆省发现并描述了一个新种线虫。该新种的特征为：雄虫体长807至963微米，雌虫体长792至1094微米；头部区域偏移；侧区有四条刻线；口针长15至16微米；排泄孔位于神经环相对处或后方。咽腺在肠的背侧重叠，延伸90至121微米；两性的尾端均具短尖。阴道向前；交合刺相对较大（27 - 32微米），顶端宽阔圆润且具关节突，发育良好。该新种与该属的七个已知物种相近，即[此处原文未列出具体物种名]，但在虫体大小、口针长度、交合刺大小以及阴门后子宫囊长度等方面与之不同。基于28S和18S rDNA的D2 - D3扩增区域序列进行的系统发育分析结果，证实了它作为一个新物种的地位。
