In a comprehensive survey of plant-parasitic nematodes of Gilgit Province, Pakistan, Quinisulcius capitatus (Allen, 1955) Siddiqi, 1971, was detected from 10 localities at high population density (≥1000 nematodes/100 g of soil) infecting different crop plantations. Morphplogical and molecular variations using principle component analysis of Q. capitatus have been given in this research. This species is characterized by body length (605–856 μm in females and 536–662 μm in males), stylet length (13–19 μm), pharynx (114–174 μm), tail length (40–56 μm in females and 38–50 μm in males), spicules (16–22 μm) and gubernaculum (6–8 μm). Principal component analysis (PCA) revealed the morphometric variation among the Pakistani populations of Q. capitatus. Phylogenetic analysis using the D2-D3 segment of 28S rDNA and ITS rDNA placed the Pakistani population of Q. capitatus in a clade with 100 posterior probability supports. Table with measurements, line illustrations, LM photographs, PCA plot and phylogenetic position for Q. capitatus within Dolchodoridae is given.

在对巴基斯坦吉尔吉特省的植物寄生线虫进行的全面调查中，从10个人口密度高的地方（≥1000线虫/ 100 g土壤）感染了不同的种植园，检测到了奎尼苏达人（亚伦，1955年）西迪奇。这项研究给出了使用Q. capitatus主成分分析的形态学和分子变异。该物种的特征是体长（雌性为605–856μm，雄性为536–662μm），管心针长度（13–19μm），咽（114–174μm），尾巴长度（雌性和雌性为40–56μm）。雄性38–50μm），针状体（16–22μm）和古柏（6–8μm）。主成分分析（PCA）显示巴基斯坦Q.capitatus种群之间的形态变化。使用28S rDNA和ITS rDNA的D2-D3区段进行系统发育分析，将巴基斯坦Q. capitatus种群置于具有100个后验概率支持的进化枝中。给出了在Dolchodoridae中的Q. capitatus的测量表，线条图，LM照片，PCA图和系统发生位置。
