The holotype was requested for study but so far it is unavailable. However, we do not consider this a major drawback since in a recent contribution, Ott et al. (2015) synonymized Neonella cabana with Neonella montana based on specimens collected in southern Brazil, which had been noted as a possibility by Galiano (1998). In agreement with Ott and collaborators, we found that males of Neonella montana have variations in both somatic and reproductive structures. Therefore, an updated diagnosis including both sexes and an additional re-description of the male including the variation found in the palp of specimens from Argentina (near the type locality) are given below.
Males of Neonella montana are similar to those of Neonella colalao in sharing a comb-like, branched lamella of embolus (LE), but can be distinguished from this species by having non bifurcated terminal apex of the embolus (Fig. 3E; and Galiano (1998): Figs 11, 12, compare with Figs 7-10). Females of Neonella montana can be distinguished from the other species of Neonella by having only one opening on the epigynal plate, formed by a large, trapezoid atrium (Fig. 4E; and Galiano 1988: 447, Figs 14, 21).
Male from Ciudad de Córdoba (IBSI-Ara 00243) (Fig. 3). Total length: 1.47. Carapace 0.67 long, 0.47 wide, 0.32 high; abdomen 0.67 long, 0.44 wide. Eye sizes: AME 0.15, ALE 0.10, PME 0.025, PLE 0.090. Ocular quadrangle 0.35 long. Anterior eye row 0.50 wide, posterior 0.50 wide. Clypeus height 0.012. Teeth of chelicerae inconspicuous. Sternum longer (0.32) than wide (0.22). Leg measurements: I 0.96 (0.31, 0.32, 0.17, 0.15); II 0.80 (0.25, 0.27, 0.15, 0.12); III 0.96 (0.27, 0.32, 0.19, 0.17); IV 1.15 (0.32, 0.40, 0.22, 0.20). Carapace light brown with narrow black margins. Cephalic region black, covered by white hairs; thoracic region with a lighter longitudinal band. Clypeus very low. Chelicerae tiny, yellow, light brown proximally. Legs light brown, with blackish irregular bands on femurs side (pro and retrolateral), and blackish rings around the distal ends of the patella and tibia, and scarcely on metatarsus. Sternum and labium yellow. Palp (Fig. 3 C–E): brown; cymbium yellow. Femur and patella black proximally, with a hook-shaped retrolateral apophysis (PA). Copulatory bulb light brown, with conspicuous tegular lobe (TL) and embolus base (EB). Embolus (E) short, with comb-like lamella (LE). Abdomen light brown, with a few scattered black hairs; with a pair of longitudinal dark stripes on the abdomen in anterior half, and the posterior half with chevrons. Dorsal abdomen completely covered with a scutum (DS). Spinnerets pale yellow. Variation (n=10): some specimens from Córdoba vary in thickness and shape of embolus and LE respectively; for comparison see Figure 4E; in addition, the blackish irregular bands of the femora may be less developed.
Female (Holotype, MACN-Ar 8409). The female is well illustrated and described in previous contributions: See Galiano (1988): 447 and illustration in Ott et al. (2015).
