Material examined: 1 male, 1 female, CHINA: Hainan, Jianfengling National Natural Reserve, Huxiaolongyin Scenic Area (18°45.159´N, 108°54.604´E), 900 m a.s.l., 20 July 2007, C. Wang leg. (WangCX 53); 1 male, CHINA: Hainan, Bawangling National Natural Reserve (19°04.871´N, 109°07.395´E), Yajia Bawangling Convention Center, 654 m a.s.l., 27 July 2007, S. Li leg. (LiSQ 106). All specimens deposited in IZCAS.
Comparative material: Opopaea deserticola Simon, 1891 (Figs 1Q, S, T, 7, detailed description see Platnick and Dupérré, 2009). 6 males, 14 females, Fort Myers Beach (26°26'N, 81°56'W), Florida, USA, Mar. 17, 1954 (W. Ivie, AMNH PBI _OON 1265); 1 male, 4 females, Fort Myers (26°38'N, 81°50'W), Florida, USA, Mar. 18, 1954 (W. Ivie, AMNH PBI _OON 1326); 6 males, 9 females, South Bimini, Bahama Islands, May 1951 (W. Gertsch, M. Cazier, AMNH PBI _OON 1254).
Diagnosis: This species is very similar to O. deserticola Simon, 1891, but can be distinguished by the shape and size of palpal bulb (bulb nearly as wide as palpal patella in O. sauteri, but distinctive narrower than palpal patella in O. deserticola) and the outgrowths on the distal part of bulb (compare Figs 1P, Q, 6A–C and 7A–C); by the median postgynal depression with smooth posterior margin, but with distinctive triangular posterior margin in O. deserticola (compare Figs 1R, S); and by the larger sized eyes in both sexes (compare Figs 1U, T).
Description: Male. Yellowish brown species with yellowish legs. Body length 1.34; carapace 0.58 long, 0.45 wide; abdomen 0.82 long, 0.55 wide. Habitus as in Figs 1G, N. Carapace sides with finely longitudinal streaks; dorsal area smooth with some hairs at lateral edges. Eyes six, well developed, ALE largest, PLE smallest; posterior eye row straight from above; ALE separated by less than their radius, ALE-PLE separated by less than ALE radius, PME touching throughout most of their length, PLE-PME separated by less than PME radius (Fig. 6D). Clypeus margin unmodified; clypeus height about 0.75 times of ALE diameter. Sternum longer than wide, uniform, fused to carapace; radial furrows present between coxae I-II, II-III, III-IV, with rows of small pits; surface smooth, without pits, microsculpture only in furrows. Anterior end of endites with a small, sharply pointed projection. Legs short, thick and spineless. Measurements of legs: I 1.04 (0.34, 0.18, 0.21, 0.18, 0.13); II 1.04 (0.34, 0.18, 0.21, 0.18, 0.13); III 0.83 (0.29, 0.13, 0.14, 0.16, 0.11); IV 1.19 (0.37, 0.21, 0.26, 0.22, 0.13). Leg formula: 4>1=2>3. Abdominal dorsal scutum strongly sclerotized, punctate, covering full length of abdomen. Book lung covers very small, ovoid, without setae. Pedicel tube short, ribbed, with small, dorsolateral, triangular extensions, scuto-pedicel region with paired curved scutal ridges (Fig. 6E), scutum not extending far dorsal of pedicel. Sperm pore small, clearly discernible, transverse; posteriorly directed apodemes present. Colulus very small, with two short setae; spinneret scutum present, incomplete ring. Supra-anal scutum absent. Patella of palp greatly enlarged and swollen, shorter than cymbiobulbus, attached to femur subbasally; cymbium completely fused to bulb without suture line; embolus simple, without distinct outgrowths (Figs 6A–C).
Female. As in male except as noted. Body length 1.42; carapace 0.58 long, 0.45 wide; abdomen 0.89 long, 0.66 wide. Endites without projections. Measurements of legs: I 1.00 (0.34, 0.18, 0.19, 0.16, 0.13); II 1.02 (0.34, 0.18, 0.21, 0.18, 0.11); III 0.87 (0.29, 0.13, 0.16, 0.18, 0.11); IV 1.23 (0.37, 0.21, 0.26, 0.26, 0.13). Postgynal depression of epigastric area shallow, without parmula, but with a small pit visible through cuticle (Fig. 6F). Vulva with a short, T-shaped sclerite, situated near epigastric furrow (Fig. 6G).
Distribution: China (Taiwan, new to Hainan) (Map 2).
