Remarks.

Tetragnatha major  and T. riparia  were described by Holmberg (1876), but the original descriptions are very short, without any suitable characters to correctly diagnose the species. There is a lack of illustrations and no type materials are specified because Holmberg did not collect the specimens he described. No specimens labeled as types of either species were found in MACN during our visit to that collection; Galiano and Maury (1979) had previously determined this. Despite the lack of information on these two species, both were subsequently reported from many localities from Argentina (e.g. Mello-Leitão 1941, 1942). However, we re-examined many of these specimens at the MACN and MNRJ and they belong to either T. argentinensis  or T. nitens  . Therefore, we treat both species as nomina dubia.
