We investigated the morphology and morphometry of eggs from the colonies of the Entomology Laboratory at ENCB-IPN belonging to six species of the genus Meccus and Triatoma recurva, using both light and scanning electron microscopy. Egg ornamentation is an important parameter to consider in the differentiation of species. Samples were observed under a scanning electron microscope. Measurements of fifty eggs per species included length, width, and opercular diameter, which were used for the morphometric analysis. The results showed that the seven species display a polygonal ornamentation dominated by hexagons; the operculum shows also a polygonal ornamental characteristic in each species. Morphometry provided valuable information for discriminating between closely related species of the genus Meccus and Triatoma recurva, a species akin to this group, thereby facilitating the complete discrimination of these species.
我们使用光学显微镜和扫描电子显微镜，对隶属于梅科斯属六种昆虫以及弯锥蝽的、来自国立理工学院生物科学系昆虫学实验室种群的虫卵进行了形态学和形态测量学研究。卵的纹饰是物种鉴别中需要考虑的一个重要参数。样本在扫描电子显微镜下进行观察。对每个物种的五十枚卵进行测量，测量内容包括长度、宽度和卵盖直径，这些数据用于形态测量分析。结果表明，这七个物种呈现出以六边形为主的多边形纹饰；每个物种的卵盖也呈现出多边形的纹饰特征。形态测量学为区分梅科斯属亲缘关系较近的物种以及与该类群相近的弯锥蝽提供了有价值的信息，从而有助于对这些物种进行全面鉴别。
