Meloidogyne mayaguensis n. sp. is described and illustrated from specimens obtained from galled roots of eggplant, Solanum melongena L., from Puerto Rico. The perineal pattern of females is round to ovoid with fine, widely spaced striae. It has occasional breaks of striation laterally and a circular tail tip area lacking striae. The stylet, 15.8 mum long, has reniform knobs that merge gradually with the stylet shaft. Males have a high, rectangular, smooth head region, not set off from the body contour. The labial disc is continuous with the medial lips which do not slope posteriorly. The styler, 22.9 mum long, has large rounded backward sloping knobs; the shaft is of uneven diameter. Mean body length of second-stage juveniles is 453.6 mum. The truncate head region is not annulated, and the rounded, slightly raised labial disc and the crescentic medial lips form dumbbell-shaped lip structures. The stylet, 11.6 mum long, has rounded, posteriorly sloping knobs. The slender tail, 54.4 mum long, gradually tapers to a bluntly pointed tip. Tomato, tobacco, pepper, and watermelon are good hosts; cotton and peanut are not hosts. M. mayaguensis n. sp. reproduces by mitotic parthenogenesis and has a somatic chromosome number of 2n = 44-45. The enzyme patterns are unique among Meloidogyne species.
马亚圭斯根结线虫新种（Meloidogyne mayaguensis n. sp.）是根据从波多黎各茄子（Solanum melongena L.）的虫瘿根中获取的标本进行描述和绘图的。雌虫会阴花纹圆形至卵形，有细小、间距宽的条纹。侧面偶尔有条纹中断，尾部顶端圆形区域无条纹。口针长15.8微米，有肾形瘤，与口针杆逐渐融合。雄虫头部区域高、呈长方形且光滑，与身体轮廓无明显分界。唇盘与内侧唇连续，内侧唇不向后倾斜。交合刺长22.9微米，有大的圆形向后倾斜的瘤；杆部直径不均匀。二龄幼虫平均体长453.6微米。截形头部区域无环纹，圆形、稍隆起的唇盘和新月形内侧唇形成哑铃形唇结构。口针长11.6微米，有圆形、向后倾斜的瘤。细长的尾部长54.4微米，逐渐变细至钝尖。番茄、烟草、辣椒和西瓜是良好的寄主；棉花和花生不是寄主。马亚圭斯根结线虫新种通过有丝分裂孤雌生殖繁殖，体细胞染色体数为2n = 44 - 45。酶谱在根结线虫种类中是独特的。
