Three new species of Notidobiella Schmid (Insecta: Trichoptera) are described from South America: Notidobiella amazonianasp. n. (Brazil), Notidobiella brasilianasp. n. (Brazil), and Notidobiella ecuadorensissp. n. (Ecuador). In addition, the 3 previously described species in the genus, Notidobiella chacayana Schmid, Notidobiella inermis Flint, and Notidobiella parallelipipeda Schmid, all endemic to southern Chile, are redescribed and illustrated, including the females of each species for the first time, and a key to males of the species in the genus is provided. The occurrence of Notidobiella in Brazil and Ecuador represents a significant extension of the range of the genus beyond southern Chile where it previously was thought to be endemic. The biogeography of Sericostomatidae and other austral South American Trichoptera is reviewed. The presence of the family in South America may not be part of a "transantarctic" exchange, but instead may represent an earlier occurence in the region. The distribution of Notidobiella in tropical South America likely represents recent dispersal from southern South America to the north.
本文描述了采自南美洲的Notidobiella Schmid属（昆虫纲：毛翅目）的三个新物种：亚马逊Notidobiella amazonianasp. n.（巴西）、巴西Notidobiella brasilianasp. n.（巴西）和厄瓜多尔Notidobiella ecuadorensissp. n.（厄瓜多尔）。此外，还对该属之前描述的3个物种，即智利南部特有的查卡亚纳Notidobiella chacayana Schmid、无刺Notidobiella inermis Flint和平行Notidobiella parallelipipeda Schmid进行了重新描述和绘图，首次包括了每个物种的雌性，并提供了该属雄性物种的检索表。Notidobiella在巴西和厄瓜多尔的出现代表了该属分布范围从之前认为是其特有分布的智利南部显著扩展。对丝角石蛾科和其他南美洲南部毛翅目的生物地理学进行了综述。该科在南美洲的存在可能并非“跨南极”交换的一部分，而可能代表了该地区更早的出现。Notidobiella在南美洲热带地区的分布可能代表了最近从南美洲南部向北的扩散。
