Fourteen populations of were collected from different agroecological regions of India. Morphological and morphometrical comparisons were made for various nematode life stages. Three populations (Hisar, New Delhi, and Samastipur) were different from typical on the basis of the length of eggs; J2 length, -value, hyaline tail portion; male length, distance up to excretory pore, spicule and gubernaculum lengths; female length and width, stylet length, distance up to excretory pore, EPST (distance of excretory pore from anterior end / stylet length [females]) ratio, and vulval length. Morphological and morphometrical comparison with closely related species , , , , and clustered these populations into two groups: Anand, Bhubaneswar, Hyderabad, Jammu, Jorhat, Kalyani, Kanpur, Ludhiana, Mandya, Palampur, Vellayani grouped with , and ; whereas, Hisar, New Delhi, Samastipur grouped with and . Molecular phylogenetic analysis using internal transcribed spacer (ITS) suggested that in spite of morphological differences, these populations belonged to .
从印度不同农业生态区域收集了14个[具体物种名称未给出]种群。对各种线虫生活阶段进行了形态学和形态测量学比较。三个种群（希萨尔、新德里和萨马斯蒂布尔）在卵的长度、J2长度、[具体参数未给出]值、透明尾部部分、雄虫长度、到排泄孔的距离、交合刺和引带长度、雌虫长度和宽度、口针长度、到排泄孔的距离、EPST（排泄孔距前端的距离/口针长度[雌虫]）比值以及阴门长度方面与典型的[具体物种名称未给出]不同。与近缘物种[具体物种名称未给出]、[具体物种名称未给出]、[具体物种名称未给出]、[具体物种名称未给出]和[具体物种名称未给出]的形态学和形态测量学比较将这些种群分为两组：阿南德、布巴内斯瓦尔、海得拉巴、查谟、乔哈特、卡利亚尼、坎普尔、卢迪亚纳、曼迪亚、帕拉姆布尔、韦拉亚尼与[具体物种名称未给出]、[具体物种名称未给出]归为一组；而希萨尔、新德里、萨马斯蒂布尔与[具体物种名称未给出]、[具体物种名称未给出]归为一组。使用内部转录间隔区（ITS）进行的分子系统发育分析表明，尽管存在形态差异，但这些种群属于[具体物种名称未给出]。
