Diagnosis. Dorsal scutum beta-shaped in dorsal view, with shallow cheliceral sockets. Dorsal scutum and free tergites entirely unarmed except for a pair of small tubercles on area I and a pair of paramedian tubercles or rounded-tip spines on area III. Reticulate pattern of blots bordering carapace and scutal areas I – III (being diffuse or weak in areas II and III in some species) and invading area IV ( Figures 2 , 7 – 11 and 15 ). Pedipalpal tibia asymmetrical, with maximum width at 3/4 length ( Figure 4 (a – b)). Chelicerae weak, monomorphic, with reduced armature on posterior and ectal margins of bulla ( Figure 4 (e)); movable finger with a medium to large basal tubercle ( Figure 4 (d), except in N. frigida ). All legs moderately elongate (femur IV approximately 1.5 times body length), with femora straight and podomeres cylindrical and unarmed ( Figures 2 (b), 3, 13 and 16). Coxa IV granulated, convex and entirely visible in dorsal view, without groin warts ( Figures 2 (a), 8(b), 12(c), 15(b) and 16b). Ventral plate of penis rectangular ( Figures 5b and 14c ); glans immersed in a depression of truncus ( Figures 5 (a) and 14(a – b)); stylus with ventral laminar process (VLP; Figure 5 (d – e), absent or reduced in N. venezuelensis ). Macrosetae C1 – C2 large, flat, curved and twisted ( Figures 5 (a,e) and 14(a – d)); D1 – D2 and A1 – A2 straight, pointed basally ( Figures 5 (b,d) and 14(a – d)); small ventral B, E1 – E2 ( Figure 5 (b)).

Remarks. All the species here transferred to Neocynorta fit with our generic diagnosis. We recognise those species as members of Neocynorta based on the reticulate pattern of blots on the dorsal scutum; dorsal scutum beta-shaped in dorsal view, with shallow cheliceral sockets, cheliceral movable finger with a median basal tubercle (except N. frigida ) and stylus with VLP visible in most species schematised by González-Sponga (not evident in N. lata , N. meridensis , N. sanarensis , N. tovarzeai and N. yaracuyana ).
