We describe and compare the morphology and morphometry of the egg exochorion for five species and two morphotypes of Mexican triatomines with scanning electron microscopy. The results show differences in egg ornamentation for each species, including between morphotypes. Polygonal ornamentation was observed in each species, including pentagons, octagons and, in certain cases, a majority of hexagons. We observed small perforations in T. protracta protracta, small spheres on the T. lecticularia polygons, a crown with festoons in T. barberi, and less complex ornamentation in T. mexicana. Through morphometric analysis, significant differences in egg dimensions were determined for the studied species.
我们用扫描电子显微镜描述并比较了墨西哥锥蝽五个物种和两种形态型的卵外卵壳的形态和形态测量学特征。结果显示，每个物种的卵纹饰存在差异，包括不同形态型之间。在每个物种中都观察到了多边形纹饰，包括五边形、八边形，在某些情况下，还有多数的六边形。我们在伸展锥蝽中观察到小穿孔，在细锥蝽的多边形上观察到小球体，在巴氏锥蝽上观察到带有花彩的冠状物，而墨西哥锥蝽的纹饰则较不复杂。通过形态测量分析，确定了所研究物种在卵尺寸上存在显著差异。
