Neriene aquilirostralis Chen & Zhu, 1989: 160   , f. 1–11 (Dmf); Song, Zhu & Chen, 1999: 188, f. 108E–F, O–P (mf).

Material examined. Hubei: GoogleMaps   Shennongjia Forestry District, Liujiawu   GoogleMaps , 31.55°N, 110.36°E, 1500m,, S. Q. Li and J. Chen leg., 6MM and 24FF (CBEE); Hubei: Luotian County, Tiantangzai National Forest Park, 31.11°N, 115.73°E, 946m, 26.x.2009, X. Xu & H.J. Xie leg., 3MM and 1F ( CBEE) GoogleMaps   ; Sichuan: Baoxing County, Wulong Town , 30.41°N, 102.77°E, 1058m,, J.

Diagnosis: This species is similar to Neriene oidedicata (Van Helsdingen, 1969)   in having flat, broad and branched distal arm of paracymbium, distal suprategular apophysis with hook-shaped tip of dorsal arm and membranous ventral tip, the small atrium opening ( Figs 7–8 View FIGURE 7 View FIGURE 8 , 9 View FIGURE 9 C–E, 50–51, 52C–E), but can be distinguished from the latter by the following characters: 1, the tip of terminal apophysis significantly membranous, beak-shaped in N. aquilirostralis   , but not in N. oidedicata   ( Figs 7F View FIGURE 7 , 8E View FIGURE 8 , 50E View FIGURE 50 , 51D View FIGURE 51 ); 2, the vulva square-shaped in N. aquilirostralis   , but trapezoid-shaped in N. oidedicata   ( Figs 7 View FIGURE 7 G–H, 9D–E, 50G–H, 51D–E).

Description: The measurements see Chen & Zhu (1989). Male palp ( Figs 7 View FIGURE 7 A–C, 7E–F, 8): Tibia shorter than cymbium, with several long spines on lateral and ventral surfaces, and one prodorsal, two retrodorsal trichobothria. Paracymbium developed, U-shaped, with two flat, broad branches distally, both branches with sharp ends. Distal suprategular apophysis slender, distally bifurcate and significantly curved backwards, dorsal part with narrow hooked tip, ventral part significantly broader than dorsal part. Lamella well-developed, with four projections: lateral one long, with a slightly wide, flat end curved upwardly, and posterior one slightly long and slender; anterior one large, blunt, with round margin, and with a small apophysis anteriorly; dorsal one short. Terminal apophysis spiral, with about two and a half coils, with the tip significantly membranous, beak-shaped. Embolus with long and slender appendage, and distal spermduct-tooth, appendage pigmented at base next to tooth but without second tooth. Male habitus as in Fig. 9B View FIGURE 9 .

Epigynum ( Figs 7D View FIGURE 7 , 9C View FIGURE 9 ): In ventral view, atrium opening small. Parmula arising from dorsal wall, tip of parmula curved in ventral direction. Vulva ( Figs 7 View FIGURE 7 G–H, 9D–E): Vulva as long as wide; copulatory grooves starting laterally, with about two and a half coils; fertilization grooves enter the spermathecae, with about two and a half coils; turning-points situated mesally, pointing towards sides; spermathecae long, slender, pointing mesad. Female habitus as in Fig. 9A View FIGURE 9 .

Distribution: China (Hainan, Hubei, Hunan, Sichuan, Yunnan) ( Fig. 69 View FIGURE 69 ).
