The sand fly Lutzomyia cruciata has been associated with the transmission of Leishmania mexicana to humans in Mexico. This species has a wide distribution in Mexico occupying different microhabitats and environments. In this work comparisons of the egg exochorion of Lu. cruciata from different physiographic areas are presented. Study sites are from different states of southern Mexico. Exochorion analysis was carried out using scanning electron microscopy (SEM). Results show differences in the exochorionic pattern among samples from Veracruz (AVER), Yucatán (HOYU) and Chiapas (TACH). The morphotype "Chiapas" has a polygonal crest pattern, the morphotype "Veracruz" shows parallel and longitudinal crests with some or few connections, and the morphotype "Yucatán" has weak connections between crest ridges. These morphological differences could be the result of local adaptations or evidence of divergence within the nominal unit Lutzomyia cruciata.
在墨西哥，沙蝇克氏白蛉已被证实与墨西哥利什曼原虫向人类的传播有关。该物种在墨西哥分布广泛，占据着不同的微生境和环境。在这项研究中，我们对来自不同自然地理区域的克氏白蛉的卵外卵壳进行了比较。研究地点来自墨西哥南部的不同州。使用扫描电子显微镜（SEM）对外卵壳进行了分析。结果显示，来自韦拉克鲁斯（AVER）、尤卡坦（HOYU）和恰帕斯（TACH）的样本在外卵壳图案上存在差异。“恰帕斯”形态型具有多边形嵴纹图案，“韦拉克鲁斯”形态型呈现平行且纵向的嵴纹，有一些或很少的连接，而“尤卡坦”形态型在嵴纹之间的连接较弱。这些形态学差异可能是局部适应的结果，或者是克氏白蛉这个名义分类单元内分化的证据。
