Material examined. 1♂ (Topotype; MHBU-ARA-00023614), CHINA: Hainan Island, Ledong County, Jianfengling National Park , Mingfenggu , 9 April 2016, leg. C. Jin & J. He ; 1♂ 1♀ (MHBU-ARA-00023641~MHBU-ARA-00023642), CHINA: Hainan Island, Sanya City, Haishishanmeng Scenic Area , 18.2533°N, 109.5457°E, 369m elev., 23 July 2022, leg. W. Wang , HBUARA#2022-133.

Diagnosis. It can be distinguished from all other congeners by its straight spine-like RTA, domed top margin of LPT and the absence of VFB in males ( Fig. 210 ), and the presence of rough central area which has a large number of small pits on sternum of females ( Fig. 207 ).

Description. Male. See Song, Gu & Chen (1988).

Female. Habitus as shown in Fig. 204 . Carapace length 2.92; abdomen length 3.15; measurements of eyes:AME 0.62, ALE 0.41, PME 0.12, PLE 0.33; measurements of legs: I 4.85 (1.57, 0.93, 1.04, 0.74, 0.57), II 4.44 (1.53, 0.87, 0.90, 0.66, 0.48), III 4.75 (1.54, 0.69, 0.97, 0.93, 0.62), IV 5.43 (1.75, 0.77, 1.26, 1.04, 0.61); leg formula 4132. Body rather dark, sternum with dense pits centrally; ventral surface of each trochanter flat.

Epigynum ( Fig. 212 ): outer rim of each atrium extending upwards and connecting each other, forming a large but very shallow concave area at upper part of epigynum. Vulva ( Fig. 213 ): accessory glands with many small branches distally.

Natural History. All specimens were collected from cracks of tree trunks or handrails ( Figs 19, 23 ).

Distribution. China (Hainan).
