Meloidogyne morocciensis n. sp. is described from specimens parasitic on peach rootstock from Morocco. This species exhibits a combination of morphological characters similar to M. arenaria, M. incognita, and M. javanica. The perineal pattern of females is oval to squarish with a moderately high to high dorsal arch, and widely spaced, smooth striae; lateral lines are absent. The stylet, 16.5 mum long, has transversely ovoid, set-off knobs. Males have a set-off, annulated head region. The large, rounded labial disc is distinctly demarcated from the crescent-shaped medial lips; lateral lips are absent. The robust stylet, 24.6 mum long, has large, rounded knobs that taper slightly posteriorly. Mean second-stage juvenile (J2) length is 401 mum. The set-offhead region has incomplete annulations; the lip structures are dumbbell shaped. The stylet, 12.3 mum long, has rounded knobs that slope posteriorly. The J2 tail, 52.6 mum long, has irregularly sized annules in the posterior region and ends in a bluntly rounded tip. Tomato, tobacco, pepper, and watermelon are good hosts; cotton and peanut are not hosts. Meloidogyne morocciensis n. sp. reproduces by mitotic parthenogenesis and has a somatic chromosome number of 47-49. Its esterase phenotype is identical with the three-banded phenotype (A3) of M. arenaria.
摩洛哥根结线虫新种(Meloidogyne morocciensis n. sp.)是根据寄生于摩洛哥桃砧木上的标本描述的。该物种呈现出与南方根结线虫(M. arenaria)、爪哇根结线虫(M. javanica)和花生根结线虫(M. incognita)相似的形态特征组合。雌虫会阴花纹为椭圆形至方形,背弓中等高至较高,条纹间距宽且平滑;无侧线。口针长16.5μm,有横向卵形、突出的瘤。雄虫头部区域突出且有环纹。大的圆形唇盘与新月形的中唇明显分界;无侧唇。粗壮的口针长24.6μm,有大的圆形瘤,向后逐渐变细。二龄幼虫(J2)平均长度为401μm。突出的头部区域环纹不完整;唇结构呈哑铃形。口针长12.3μm,有向后倾斜的圆形瘤。J2尾部长度为52.6μm,后部区域有大小不规则的环纹,末端为钝圆形。番茄、烟草、辣椒和西瓜是良好的寄主;棉花和花生不是寄主。摩洛哥根结线虫新种通过有丝分裂孤雌生殖进行繁殖,体细胞染色体数为47 - 49。其酯酶表型与南方根结线虫的三带表型(A3)相同。
