Male holotype (Fig. 1) total length 4.54. Prosoma 2.22 long, 1.98 wide; Opisthosoma 2.80 long, 1.84 wide. Carapace brown, irregular-shaped, with yellowish-brown radial markings extending from the fovea. Fovea vertical. Cervical groove and radial furrows distinct. Eye sizes and interdistances: AME 0.14, ALE 0.18, PME 0.16, PLE 0.17; AME – AME 0.06, AME – ALE 0.04, PME – PME 0.15, PME – PLE 0.08, ALE – PLE 0.03. MOA 0.40 long, anterior width 0.35, posterior width 0.45. Clypeus height 0.24. Chelicerae, brown, with three promarginal and two retromarginal teeth. Labium brown, wider than long. Endites brown, longer than wide. Sternum yellowish-brown and scutellate with sparse black hairs. Leg measurements: I 10.06 (2.89, 3.48, 2.31, 1.38); II 7.92 (2.23, 2.70, 1.80, 1.19); III 6.66 (1.85, 2.20, 1.52, 1.09); IV 7.93 (2.03, 2.57, 1.99, 1.34). Leg formula: 1423. Opisthosoma oval, dorsum yellowish-brown, dorsally with five light chevrons, venter yellowish-brown. Palp (Figs 2, 3). Patella with short apophysis (PA), curving and with a hook end. Retrolateral tibia apophysis (RTA) arc-shaped in ventral and dorsal view, helical-shaped in retrolateral view. The embolus (E) originating at about 6: 00 o’clock position, clockwise curved along the bulbus margin. Female. Unknown. Diagnosis The new species is similar to N. quelpartensis Paik, 1958 (Figs 4, 5) in having similarly shaped patellar and tibia retrolateral apophyses, but it can be distinguished by the rounded tegulum (vs. oval, cf. Fig. 2 A, Fig. 3 A and Fig. 5 A), the embolus originating at about 6: 00 o’clock position (vs. 5: 30, cf. Fig. 2 A, Fig. 3 A and Fig. 5 A), the strong patellar apophysis (vs. puny, cf. Figs 2, 3 and Fig. 5). Etymology The specific name is derived from the type locality; noun in apposition. Distribution Known only from the type locality. Biology Living under stones by the stream, weaves a small net.
