Figs 4–5 , 9

Neriene sinense Chen, 1991: 164 , f. 2A–D; Song, Zhu & Li, 1993: 866, f. 27A–D; Song, Zhu & Chen, 1999: 194, f. 112C–D, M–N;

P. sinense ( Chen, 1991) : Tu & Li, 2006: 113, f. 9A–H.

Material examined: 1 male and 7 females, China, Hainan Province: Bawangling Mountain National Nature Reserve , 19.13°N, 109.10°E, 300m, 7 June 2007, H. Yu leg. ( CBEE) .

Diagnosis: The male of this species can be distinguished from other Prosoponoides species by the long embolus with wide membrane ( Fig. 4D ) which is gradually reduced distally. The femle of this species can be differed from other Prosoponoides species by the coiled copulatory ducts ( Figs 5 D–E) which are about two and half coils in P. sinense but less than two coils in other Prosoponoides species.

Description. See Tu & Li (2006).

Distribution: China (Fujian; Hainan, new record; Zhejiang), Vietnam (Cao Bang, Sac Tay) ( Fig. 9 ).
