Abstract

Two new Neotropical species of the predaceous midge genus Austrohelea Wirth & Grogan, A. sirii n. sp. and A. spinosa n. sp., and the previously known A. shannoni (Wirth & Blanton) are described, illustrated and photomicrographs provided of male and female specimens collected from several localities in Argentine and Chilean Patagonia. The similarities and differences between the three Neotropical species are discussed, and a key is provided of the males and females of these three species. The distribution of A. shannoni is extended to the southernmost region of South America.

摘要

描述了新热带地区食蚊蠓属Austrohelea Wirth & Grogan的两个新物种，即西里Austrohelea sirii新种和多刺Austrohelea spinosa新种，以及此前已知的香农Austrohelea shannoni（Wirth & Blanton），并提供了从阿根廷和智利巴塔哥尼亚多个地点采集的雄性和雌性标本的图示及显微照片。讨论了这三个新热带物种之间的异同，并给出了这三个物种雄性和雌性的检索表。香农Austrohelea shannoni的分布范围扩展到了南美洲最南端地区。
