( Figs. 11–15)

Oxyopes labialis Song 1991: 170 , figs. 2A–D (female holotype and 1 male allotype from Jianfengling, Hainan Province, China, N 18°42’, E 108°48’, IZB, examined). — Song, Zhu & Chen 1999: 400, figs. 234A–B, 235G, 236G.

Diagnosis. This species is similar to Hamataliwa cordata sp. nov. in female epigynum with a heart­like depression, but it differs from the latter in copulatory ducts of female epigynum long and swollen at the base ( Fig. 13); tip of median apophysis of male palpal organ beak­shaped, conductor relatively simple, with a lateral lobe and a triangular process, ventral tibial apophysis small and club­like, retrolateral tibial apophysis flat ( Figs. 14–15).

Redescription.

Female (holotype): Total length 5.16. Prosoma 2.58 long, 2.10 wide; opisthosoma 2.39 long, 1.67 wide. Carapace red brown, with some white hairs and brown streaks; eyes area black brown. Chelicerae with two promarginal and one retromarginal teeth. Labium longer than wide, with dark patches on basal half.

Opisthosoma oval; dorsum white yellow, with two pairs of brown spots and five chevron­shaped brown bands across horizontal axis, posterior half of dorsum grayish laterally; venter with a mesal wide brownish longitudinal stripe behind the epigastric furrow.
