With a frontal tubercle; frons six times longer than high; first frontal row with eight or nine setae on each side; chaetotaxy of dorsal margin of hind tibia 2; 2; 2; 2; 2; 1; 2; 2; inner side of hind femur with two or three subventral setae; apical seta of movable process of clasper slightly pigmented; fixed process with three or four marginal setae, without submarginal setae; sternum VII in female with four setae and a well-developed, rounded lobe on lower portion of distal margin.......... N. rosenbergi

- Without a frontal tubercle; frons four times longer than high; first frontal row with six or seven setae on each side; chaetotaxy

of dorsal margin of hind tibia 2; 2; 1–2; 1–2; 2; 2; 2–3; 2; inner side of hind femur with five to seven subventral setae; apical seta of movable process of clasper dark; fixed process with eight to ten marginal setae, and three or four submarginal setae; sternum VII in female with five setae and distal margin rounded, almost straight, convex in the lower portion or with conspicuous lobe in the middle................................................................................. 2 2. Second and/or third abdominal tergites with one to three dorsal spinelets on each side............. N. crassispina hemisus

- Abdominal tergites without dorsal spinelets................................................................. 3

3. Males with last distal marginal seta on the fixed process of the clasper at tip or removed from tip by distance equal to the width of the fixed process at the point of attachment of the seta; distal arm of sternum IX with dorsal margin strongly concave. Female sternum VII with apical margin wide and distal margin rounded or convex in the lower portion.................. 4

- Males with last distal marginal seta on the fixed process of the clasper removed from tip by distance of about twice the width of the fixed process at the point of attachment of the seta; distal arm of sternum IX with dorsal margin slightly concave. Female sternum VII with apical margin narrow and distal margin almost straight or with conspicuous lobe in the middle......... 5

4. Males with last distal marginal seta on the fixed process of the clasper at tip of the process; apex of the crochet of the aedeagus with proximal margin bearing a large, almost rounded projection; distal arm of sternum IX with six or seven spine-like ventromarginal setae, the first three strongly pigmented and located in the apex above the others. Females with distal margin of sternum VII rounded................................................................ N. crassispina crassispina

- Males with last distal marginal seta on the fixed process of the clasper separated from its tip; apex of the crochet of the aedeagus with proximal margin bearing a large pointed projection, forming an angle ≤ 45º, distal arm of sternum IX with apex bearing one small dorsomarginal seta in the centre and seven curved setae, the first seta strongly pigmented. Female sternum VII with distal margin convex in the lower portion................................................ N. pardinasi n. sp.

5. Males with the upper lobe of the fixed process of clasper with apex clearly turned up; lower lobe of the fixed process with sharp distal edge; movable process with distal margin almost straight and ventral margin strongly indented; distal arm of sternum IX bearing five curved spine-like setae, the first seta located in the centre above the others; crochet with rounded projection on proximal margin and distal margin strongly convex. Females with distal margin of sternum VII almost straight................................................................................................. N. chilensis

- Males with upper lobe of the fixed process of clasper with apex almost straight; lower lobe of the fixed process with rounded distal edge; movable process with distal margin rounded and ventral margin slightly indented; distal arm of sternum IX bearing six curved spine-like setae, the first one located at the apex; crochet of the aedeagus with two angular projections on proximal margin and distal margin almost straight or slightly concave. Sternum VII in females with conspicuous lobe in the middle of distal margin.......................................................................... N. crackensis n. sp.
