Figures 1–6 View Figures 1‒5 View Figure 6

Type material. Male holotype ( FML 02173 View Materials ), Castellanos , Provincial Route 28, 2 km W of north of Salta city (24°43ʹ2.4ʺS, 65°26ʹ2.4ʺW, 1286 m a.s.l.), Capital Department, Salta Province, Argentina, 03.XI.2006, IEBI Team Cols GoogleMaps .

Etymology. The noun in apposition was taken from the type locality.

Diagnosis. Males of Nesticus salta sp. nov. can be recognized by: the shape of the two-branched paracymbium showing a translucent membrane between them, the ventral process of the paracymbium is slender and hook-shaped, while the dorsal one is larger, with a keel and blunt ending ( Figures 1 and 2 View Figures 1‒5 ); the great conductor with an slender base arising from the center of the bulb ( Figure 1 View Figures 1‒5 ) continuing in a very deep concave medial and distal portion ending in a three-lobulated border ( Figures 1 and 3 View Figures 1‒5 ) (prolateral lobe subrectangular, the middle one small with a sharp small tip, and retrolateral rounded); and the presence of a quadrangular suprategular process ( Figure 2 View Figures 1‒5 ). Males of N. salta sp. nov. resemble those of N. ivone Faliero and Santos, 2011 and N. brignolii by the presence of a tegulum wider than the cymbium, but differ from them by the shape of the suprategular process and the conductor. Furthermore, the absence of a median process in the paracymbium and hook-shaped paracymbium processes distinguish the males of N. salta sp. nov. from those of the former and latter species, respectively.
