Diagnosis. Males of N. guarani resembles those of N. naylienae n. sp. by having a short copulatory bulb (tegulum + embolus), the length just two times or less the palpal tibia length (Figs 1 B–C; 4B–C), but differ by the weakly swollen tegulum apical section (tas), two times wider than basal section but narrower than palpal tibia width (Figs 1 B–C, 8G) and by the beveled embolus tip with very short projections (Fig. 3 G–I). Females are readily recognized by the triangular distal margin of receptaculum (dmr) (Figs 1I; 10A). Additionally, both males and females have a darker carapace pattern if compared with all other known Nyetnops species (Fig. 1A, E, G).

Description. Male and female described by Platnick and Lise (2007): 9. Complementary description of female (IBSP 154310): External genital area with anterior and posterior plates slightly sclerotized (Fig. 1H). Internal area with a triangular distal margin of receptaculum (Figs 1I; 10A).

Distribution. South and Southeast Brazil (Fig. 10C).
