Coelotes palinitropus Zhu and Wang 1994: 42 , figs 19–21 (holotype male, 1 male paratype from Jianfengling, Hainan, China, in NBUMS, not examined). — Song et al. 1999: 377, figs 220O, 224C; Xu and Li 2006a: 337, figs 8–13, 35– 37.

Material examined: 6 females, 2 males: China, Hainan, Jianfengling Nature Reserve, N18.7º, E108.8º, December 14, 1989 ( IZCAS); 1 female: China, Hainan, Wuzhishan Mt., N18.8º, E109.5º, April 16, 2005, Y.J. Song leg. ( IZCAS); 1 female: Hainan, Diaoluoshan Nature Reserve, N18.7º, E109.8º, April 19, 2005, Y.J.

Song leg. ( IZCAS); 1 female: China, Hainan, Baoting County, Maogan Xiang, Xian An, Shilin cave, N18.7º, E109.8º, March 2005, Y.F. Tong leg. ( IZCAS).

Diagnosis: Females of N. palinitropus can be easily distinguished by the elongated atrium which is 4–5 times longer than wide ( Figs 17 , 23 , 25 ). Males can be easily distinguished from N. vietnamensis sp. nov. by the reduced median apophysis (large in N. vietnamensis ), and from N. sparus by the semi-circular conductor (proximally extended and only slightly coiled in N. sparsus ) ( Figs 19–22 ).

Description: Females: Described by Xu and Li (2006a). Medium sized coelotine, total length 8.26–9.40. One female from Hainan, Jianfengling Nature Reserve: Total length 8.26. Dorsal shield of prosoma 3.91 long, 2.61 wide; opisthosoma 4.35 long, 3.04 wide. Eye sizes and interdistances: AME smallest, slightly more than half the size of other eyes which are subequal (AME 0.09, ALE 0.15, PLE 0.15, PME 0.14); AME separated by approximately their diameter; AME and ALE slightly separated, other eyes distinctly separated (ALE–PLE 0.06, PME–PME 0.09, PME–PLE 0.12, AME–PME 0.12) ( Fig. 26 ). Chelicerae with 3 promarginal and 2 retromarginal teeth. Legs normal length (I 11.30; II 9.45; III 7.60; IV 12.28) (1st leg/dorsal shield of prosoma = 2.90). Epigynum without teeth; atrium strongly elongated, with length 4–5 times longer than width; posterior margin of atrium with a tongue-shaped, posteriorly directed atrial scape; copulatory ducts large, anteriorly originated, posteriorly folded, covering anterior part of spermathecae; spermathecal bases broad, widely separated by copulatory ducts; spermathecal heads covered by copulatory ducts ( Figs 17–18 , 23–25 ).

Males: Described by Zhu and Wang (1994). Medium sized coelotine, total length 6.70–7.70. Eyes and chelicerae similar to female. Palpus without patellar apophysis; RTA small; lateral tibial apophysis strongly bifurcated; cymbial furrow about half of cymbial length or slightly longer; conductor long, extending proximally, coiling and forming a semi-circular shape; conductor dorsal apophysis absent; conductor lamella large; median apophysis reduced; embolus filiform, proximal in origin, with narrow base ( Figs 19–22 ).

Distribution: China (Hainan) ( Fig. 44 ).
