ṣậḍljHḑ (ṉÿ) ( Figs. 6 View Fig S-T, 18I-O)
Material examined. Holotype: ♂, mixed forest (38°10 ʹ 04 ʺ N, 128°22 ʹ 17 ʺ E, alt. 543 m), Buk-myeon, Inje-gun, Gangwon-do, 19 July 2010, J. C. Lim. Paratypes: 10♂♂,
2$$, same data as holotype.
Etymology. The specific name is a Latin adjective “ bituberculata ” (two-tuberculate), referring to having two tubercles on the male palpal tibia.
Diagnosis. The new species resembles N. nodosa ( Oi, 1960) in the general appearance and the tibial apophysis of male palp, but different from the latter by the number of tibial apophysis and the detailed structure of male palp ( Fig. 18 View Fig I-L).
Description. Male (holotype). Total length 1.34. Habitus as in Figure 6S View Fig . Carapace dirty brown, 0.70 long, 0.56 wide. Clypeus height 2.7 times of diameter of AME. AER 0.25, PER 0.26. AER recurved and PER straight in dorsal view. AME 0.04, ALE 0.07, PME 0.07, PLE 0.05, AME-AME 0.01, AME-ALE 0.02, PME-PME 0.03, PME-PLE 0.05, AME-PME 0.05, and ALE-PLE contiguous. Median ocular quadrangle, height = posteri- or side>anterior side (3:2). Chelicera with four teeth on each margin. Sternum 0.40 long, 0.39 wide. Labium 0.12 wide. Leg measurements: I 2.57 (0.66, 0.20, 0.65, 0.60, 0.46), II 2.32 (0.61, 0.20, 0.57, 0.52, 0.42), III 1.92 (0.55, 0.18, 0.43, 0.43, 0.33), IV 2.53 (0.70, 0.20, 0.65, 0.59, 0.39). Leg I/c 3.67. Fem. I/c 0.94. Tib. I/c 0.93. Met. I/c 0.86. Pat. I + tib. I/c 1.21. Met. I/tar. I 1.30. Met. IV/tar. IV 1.51. Chaetotaxy 2-2-2-2 (male paratype). Tm 1 0.24, Tm IV absent. Abdomen oval, and long, 0.58 wide; dorsum dirty brown anteriorly, dark brown posteriorly. Palp ( Fig. 18 View Fig I-L): tibia short, with two dorsal apophyses: paracymbium U-shaped, with a proximal hump and ventral pocket in lateral view; distal suprategular apophysis bifurcate; embolus curved with pointed embolus apex and embolus proper, without embolus thumb; Lamella characteristica divided into three branches; terminal apophysis also divided into three parts - one long point- ed, another round membranous, and other small pointed. Female (paratype). Total length 1.28. Habitus as in Figure 6T View Fig . Carapace 0.64 long, 0.52 wide. Clypeus height 2.7 times of diameter of AME. AER 0.25, PER 0.26.
