Abstract

We newly diagnose, illustrate, and clarify the distribution ranges of six of the most common and broadly distributed species ofTetragnathaLatreille, 1804 found in the Neotropical region. Twenty new junior synonyms from around the world are included, nine forT. bogotensisKeyserling, 1865, four forT. mandibulataWalckenaer, 1841, three forT. keyserlingiSimon, 1890, three forT. nitens(Audouin, 1826), and one forT. elongataWalckenaer, 1841.Tetragnatha vermiformisEmerton, 1884 is newly recorded from South America. The ArgentineT. majorHolmberg, 1876 andT. ripariaHolmberg, 1876 are considered nomina dubia. Finally, we discuss the terminology of the structures of the chelicerae to establish a coherent nomenclature for teeth and fang cusps.
