The geographic distribution of Aedes (Stegomyia) aegypti (L.) in South America has been expanding during the last decades. Herein we present two new distribution records that extend its southern limits towards localities with extremer environmental conditions than reported to date. San Antonio Oeste constitutes the southernmost finding for the continent (40º44’S), whereas Tandil is the infested locality with the coldest mean annual temperature in Argentina (14.17ºC). The projection of a previous distribution model for Ae. aegypti predicts these two cities as positive and suggests several other localities with suitable conditions for vector proliferation beyond its assumed distribution limits.

埃及伊蚊在南美洲传播：新的最冷和最南端的记录。

在过去的几十年中，南美伊蚊（Stegomyia）埃及（L.）的地理分布一直在扩大。在此，我们提供了两个新的分布记录，这些记录将其南部范围扩展到环境条件比迄今报告的极端的地方。圣安东尼奥·奥埃斯特是该大陆最南端的发现（40º44'S），而坦迪尔（Tandil）是受感染的地区，阿根廷的年平均气温最低（14.17ºC）。Ae以前的分配模型的投影。aegypti预测这两个城市为阳性，并建议其他几个具有适当媒介传播条件的地区，超出其假定的分布范围。
