Type material.

Holotype ♂ (IZCAS-Ar43206), China: Hainan: Baisha County, Yinggeling National Nature Reserve (19°02.93'N, 109°33.65'E, ca. 730 m), 20.viii.2010, G. Zheng leg. Paratypes 20♂17♀ (IZCAS-Ar43207-43243), same data as holotype.


The specific name is a patronym of Mr. Runbang Zhou, our guide in Jianfengling National Nature Reserve; noun (name) in genitive case.


Philates zhoui sp. nov. resembles that of P. grammicus Simon, 1900 known from Philippines and Indonesia in the carapace sloping steeply at the posterior sub-margin, the enlarged femora I, and the dense setae ventrally on the enlarged tibia I, but it can be easily distinguished by the following characters: (1) the RTA is longer than the tibia (Fig. 15B View Figure 15 ), whereas it is ~ 1/2 the tibia length in P. grammicus ( Wanless 1978: fig. 10J); (2) the copulatory ducts are separated from each other proximally by their width (Fig. 16A, B View Figure 16 ), whereas they are touching in P. grammicus ( Wanless 1978: fig. 10D, H); (3) the male carapace lacks patches of scales (Fig. 16C, D View Figure 16 ), whereas there are patches of white scales behind the PMEs and on the slope of the thorax in P. grammicus ( Wanless 1978: fig. 10D, H). The new species is also similar to Colaxes sazailus Paul, Prajapati, Joseph & Sebastian, 2020 known from India in having very similar copulatory organs, but it can be easily distinguished by the square cephalic region, which is trapeziform in C. sazailus ( Paul et al. 2020: fig. 6, 15).


Male (Figs 15 View Figure 15 , 16C-E, G, H View Figure 16 ). Total length 2.51. Carapace 1.30 long, 1.04 wide. Abdomen 1.28 long, 1.02 wide. Eye sizes and inter-distances: AME 0.33, ALE 0.19, PLE 0.15, AERW 0.98, PERW 0.98, EFL 0.57. Leg measurements: I 2.26 (0.75, 0.43, 0.55, 0.33, 0.20), II 1.61 (0.53, 0.25, 0.30, 0.33, 0.20), III 1.56 (0.50, 0.23, 0.30, 0.33, 0.20), IV 1.86 (0.63, 0.25, 0.40, 0.38, 0.20). Carapace red-brown, acutely sloped at posterior sub-margin, the square cephalic region with two longitudinal white streaks of setae medially. Chelicerae with two promarginal and four retromarginal teeth. Endites colored as chelicerae, broadened distally. Labium sub-linguiform, dark brown, paler apically. Sternum yellow-brown, slightly longer than wide. Legs I robust, with enlarged femora and tibiae, and dense, long, dark setae ventrally on femora, patellae and tibiae; other legs pale yellow to dark brown. Abdomen oval, dorsum red-brown, paler at terminus, with longitudinal, irregular dark streak centrally, two pairs of muscle depressions medially, covered entirely by scutum, with dense, thin setae; venter colored as dorsum. Palp (Fig. 15A-D View Figure 15 ): tibia slightly wider than long, with straight, tapered RTA ~ 1.5 × of its length, and blunt apically; bulb swollen, longer than wide, sperm duct sinuous retrolaterally; embolus coiled ~ 2 ×, pointed at terminus; process of embolus disc lamellar.

Female (Fig. 16A, B, F View Figure 16 ). Total length 2.44. Carapace 1.17 long, 0.92 wide. Abdomen 1.23 long, 1.01 wide. Eye sizes and inter-distances: AME 0.31, ALE 0.16, PLE 0.15, AERW 0.87, PERW 0.87, EFL 0.51. Leg measurements: I 1.76 (0.58, 0.33, 0.40, 0.25, 0.20), II 1.41 (0.43, 0.25, 0.28, 0.25, 0.20), III 1.39 (0.43, 0.23, 0.28, 0.25, 0.20), IV 1.74 (0.58, 0.28, 0.38, 0.30, 0.20). Habitus (Fig. 16F View Figure 16 ) similar to that of male except with pair of dark spots medially in eye field. Epigyne (Fig. 16A, B View Figure 16 ): longer than wide; anteriorly located, oval atrium separated by broad, sub-oblong septum ~ 2 × longer than wide; copulatory openings beneath the lowest margin of atrium; copulatory ducts separated, widened proximally, with complex coils; spermathecae elongated; fertilization ducts lamellar, extending anterolaterally.
