Zhu leg., 1M ( CBEE) ; Guizhou: Tongren City, Fanjingshan National Nature Reserve , 27.85°N, 108.78°E, 912m, 24.vi.1985, C.D. Zhu leg., 1M and 1F ( CBEE) ; Fujian: Wuyishan National Nature Reserve , 27.63°N, 117.99°E, 1216m, 18.vii.1986, C.D. Zhu leg., 1M and 7FF .

Diagnosis: This species is significantly similar to N. nitens in genital structures, but can be distinguished from the latter by the following characters: 1, the body size of N. compta usually larger than N. nitens : total length of male ( N. nitens : 4.66–5.97; N. compta : 5.40–8.00) and female ( N. nitens : 4.76–6.87; N. compta : 5.02–8.10) ( Figs 23 A–B, 49A–B); 2, chelicerae furnished with one large tooth on a half of length of chelicera, two teeth on fourfifths of length of chelicera, both lateral-dorsal in position, promargin of fang furrow with four to five teeth, retromargin with four or six teeth in males of N. compta , but with a small tooth on two-thirds of length of chelicera, lateral-dorsal in position, promargin of fang furrow with two teeth, first much bigger than second, retromargin with five or six equally big teeth in males of N. nitens ( Figs 21C , 47D ); 3, copulatory grooves started laterally in N. compta , but rather mesally in N. nitens ( Figs 21H , 23D , 47B , 49D ); 4, spermathecae long, slender, curved and pointing laterally in N. compta , but pointing towards mesally in N. nitens ( Figs 21I , 23E , 47C , 49E ).

Description: The measurements see Zhu & Sha, 1986. Male palp ( Figs 21 A–C, 21E–G, 22): Tibia slightly shorter than cymbium. Paracymbium long, slender, U-shaped, with distal arm curved upwardly. Distal suprategular apophysis slender, distally bifurcate, dorsal part with narrow hooked tip, ventral part membranous, significantly broader than dorsal part. Lamella well-developed, with four projections: lateral one long, slender, L-shaped in the ventral view; posterior one slightly long and slender; anterior one large, blunt, with round margin; dorsal one short. Terminal apophysis spiral, with about one coil. Embolus with short appendage distally of spermduct-tooth, appendage pigmented wholly with second tooth. Male habitus as in Fig. 23B .

Epigynum ( Figs 21D , 23C ): In ventral view, atrium opening large, semicircular. Parmula arising from dorsal wall, with a semicircular tip, which has a small depression at its tip. Vulva ( Figs 21 H–I, 23D–E): Vulva wider than long; copulatory grooves started slightly laterally, with about one and a half coils; fertilization grooves enter the spermathecae, with about one and a half coils; turning-points long, slender, significantly curved, situated laterally, pointing towards mesally; spermathecae long, slender, also significantly curved, pointing towards mesally. Female habitus as in Fig. 23A .

Distribution: China (Anhui, Guizhou, Fujian, Zhejiang) ( Fig. 69 ).
