Diagnosis: See the diagnosis under N. compta .

Description: The measurements see Chen & Zhu (1992). Male palp ( Figs 48 ): 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 and tapering; posterior one long and slender; anterior one large, blunt; 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. 49B .

Epigynum ( Figs 47A , 49C ): 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 47 B–C, 49D–E): Vulva wider than long; copulatory grooves started mesally, 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 laterally. Female habitus as in Fig. 49A .
