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) (
