Eggs of Psorophora albigenu were analyzed by light and scanning electron microscopy. Eggs were laid singly and were black and elliptical in outline. A length of approximately 586.4 ± 10.83 μm, a width of 172.3 ± 8.09 μm (n=30), and an egg index (length/width ratio) of 3.33 were observed. The anterior extremity tapered abruptly from a width of 64.9 μm, while such tapering was more gradual at the posterior extremity from a width of 77.4 μm. The ventral surface of the chorionic coating presented cells with tubular aspect containing tubercles in rows with a density of 9-16 tubercles per cell. These tubercles presented two different sizes, with the largest measuring 7.87 ± 01.58 μm and the smallest measuring 0.71 ± 0.53 μm (n=30) in longitudinal diameter. The micropyle orifice was very evident, with a diameter of 3.36 μm. The morphometric characteristics of Ps. albigenu obtained in this study were distinct from those of other species of the Psorophora genus, including Psorophora varipes which has been considered for a long time to be synonymous with Ps. albigenu.
用光学显微镜和扫描电子显微镜对淡色库蚊的卵进行了分析。卵单独产下，呈黑色，椭圆形。卵的长度约为 586.4 ± 10.83 μm，宽度为 172.3 ± 8.09 μm（n=30），卵指数（长度/宽度比）为 3.33。前端从 64.9 μm 的宽度急剧变细，而后端从 77.4 μm 的宽度变细则更为渐进。卵壳表面的腹面呈现出具有管状外观的细胞，其中有呈排的结节，每细胞有 9-16 个结节，密度为 9-16 个结节/细胞。这些结节有两种不同的大小，最大的长径为 7.87 ± 01.58 μm，最小的长径为 0.71 ± 0.53 μm（n=30）。微孔口非常明显，直径为 3.36 μm。本研究中获得的淡色库蚊的形态特征与其他库蚊属物种明显不同，包括被长期认为与淡色库蚊同义的淡色库蚊。
