Scanning electron micrographs were used to describe and compare structures of eggs obtained from wild-caught females of 6 species of the Albimanus section of Anopheles (Nyssorhynchus) from South America, which includes important regional vectors of human malaria. Among species from the Oswaldoi Complex, eggs of Anopheles oswaldoi (Peryassu) were not differentiated from those of its sibling Anopheles konderi Galvão & Damasceno, and eggs of the former species from Brazil, Ecuador, and Suriname showed no regionally distinguishing characteristics. Eggs of Anopheles dunhami Causey were recognized by the reticulate beadwork of outer chorion on the dorsal plastron, 1 of several egg characters separating this species from the related Anopheles trinkae Faran and Anophels nuneztovari Gabaldón. In both species examined from the Strodei Complex, Anopheles strodei Root and Anopheles benarrochi Gabaldón, Cova Garcia & Lopez, the anterior frill forms a distinctive ventral crown separated from the floats. Anopheles triannulatus (Neiva & Pinto), collected from 4 geographic sites, differed in the occurrence of perforated mounds on the dorsal plastron, but these chorionic structures and the extent of overlap of floats varied among eggs from single females. Changes among related species in the structure of the anterior frill and dorsal plastron are described for phylogenetic and developmental inferences.
扫描电子显微镜图像用于描述和比较从南美洲按蚊(尼氏按蚊)阿尔比马努斯组6种野生雌蚊获取的卵的结构,该组包括人类疟疾的重要区域传播媒介。在奥斯瓦尔多伊复合体的物种中,奥斯瓦尔多伊按蚊(佩亚苏)的卵与其同胞康代里按蚊的卵无法区分,该前一物种来自巴西、厄瓜多尔和苏里南的卵未表现出区域特征。邓哈米按蚊的卵可通过背侧气盾外层绒毛膜的网状珠饰来识别,这是将该物种与相关的特林卡按蚊和努涅斯托瓦里按蚊区分开来的几个卵特征之一。在从斯特罗代伊复合体中检测的两个物种,即斯特罗代伊按蚊和贝纳罗奇按蚊中,前褶形成一个与浮器分离的独特腹冠。从4个地理地点采集的三带喙库蚊,其背侧气盾上穿孔丘的出现情况有所不同,但这些绒毛膜结构以及浮器的重叠程度在单个雌蚊的卵之间也有所变化。描述了相关物种在前褶和背侧气盾结构上的变化,以用于系统发育和发育推断。
