摘要

1804年，描述了南美洲长颌圆织蛛属的五个新种：亚马逊四颚蛛。11月（委内瑞拉）；T.cristasp。11月（阿根廷和巴西）；T.didoratasp。11月（巴西）；T.oncognathasp。11月（巴西）；和T.pradoisp。十一月（阿根廷和巴西）。提供了来自阿根廷和巴西的21种四颚虫的一个索引，完成了这些国家对该属的修订。对1880年的T.cladognatha Bertkau的雌性进行了重新描述，并提出了一种新的类型，首次描述了其雄性。此外，我们还更新了以下六个南美洲物种的分类状况：唇颚四颚虫（Tetragnatha lipilis Nicolet），1849年和美洲锥虫西蒙（T.americana Simon），1896年被认为是锥虫的新初级同义词（Audouin，1826）；和Tetragnatha bispisi Caporiacco，1947，T.linearis Nicolet，1849，T.similis Nicolet（1849）和T.sternalis Nicolet。

Five new species of the long-jawed orb-weaving spider genus Tetragnatha (Araneae, Tetragnathidae) in South America, with a key to the species from Argentina and Brazil

Five new species in the long-jawed orb-weaving spider genus Tetragnatha Latreille, 1804 are described from South America: Tetragnatha amazonicasp. nov. (Venezuela); T. cristatasp. nov. (Argentina and Brazil); T. didoratasp. nov. (Brazil); T. oncognathasp. nov. (Brazil); and T. pradoisp. nov. (Argentina and Brazil). A key to the 21 species of Tetragnatha from Argentina and Brazil is provided, completing the revision of the genus for these countries. The female of T. cladognatha Bertkau, 1880 is redescribed and a neotype is proposed, and its male is described for the first time. Additionally, we update the taxonomic status of the following six South American species: Tetragnatha labialis Nicolet, 1849 and T. americana Simon, 1896 are considered new junior synonymies of T. nitens (Audouin, 1826); and Tetragnatha bishopi Caporiacco, 1947, T. linearis Nicolet, 1849, T. similis Nicolet, 1849 and T. sternalis Nicolet, 1849 are proposed as nomina dubia due to missing or juvenile type-material.
