Nebridia parva Mello-Leitão, 1945: 289 (♀ Holotype from Pindapoy, Misiones, Argentina, Birabén leg., MLP 16810, examined).

Amphidraus parvus : ZHang & Maddison, 2015: 22 (transferred from Nebridia to Amphidraus after genus synonymy); World Spider Catalog 2017.

Description. See Mello-Leitão (1945).

Distribution. Known only from the type locality ( Argentina, Misiones)

Note. The genus Titanattus belongs in the clade Amycoida and is nested within a smaller clade including scopocirines, sarindines and thiodinies (See Ruiz & Maddison 2015, clade 2). The new combination is based on the similarity with the species referred to as “ Titanattus sp. D” in Ruiz & Maddison (2015), which is being described by Bustamante & Ruiz (2017, in press). New diagnostic illustration of the holotype of T. parvus is provided herein ( Fig. 27 E).
