Type material.

Holotype ♀: China, Hainan, Ledong County, Jianfengling National Natural Reserve, Mingfenggu Scenic Spot, 18°44'25.87"N, 108°50'47.83"E, 4 April 2021, Yunhu Mo leg. (Tho-292, ASM-JGSU).

Etymology.

The specific name refers to the Chinese abbreviation for Hainan Province; noun in apposition.

Diagnosis.

The female of this new species resembles Stephanopis xiangzhouica Liu, 2022 (see Liu et al. 2022c: 64, fig. A, B) in having the copulatory openings hidden by a transverse ridge, but can be distinguished by the inverted heart-shaped atrium (vs. oval) and the tube-shaped spermathecae separated by nearly as long as their width (vs. the oval spermathecae separated by their half width) (Fig. 5G, H View Figure 5 ).

Description.

Female (holotype). Habitus as in Figs 5A, B View Figure 5 , 6C, D View Figure 6 . Total length 5.46, prosoma (Fig. 5A, B View Figure 5 ) length 2.32, width 2.86, anteriorly narrowed to 0.43 × its maximum width, covered with numerous strong, short, radially distributed peg-like setae and dense short plumose setae, with three rows of short, strong setae along the midline. Eye diameters (Fig. 5C View Figure 5 ): AME 0.05, ALE 0.11, PME 0.08, PLE 0.09; interdistances: AME-AME, 0.10, AME-ALE, 0.12, PME-PME, 0.25, PME-PLE, 0.14, AME-PME, 0.36, AME-PLE, 0.39, ALE-ALE, 0.37, PLE-PLE 0.67, ALE-PLE, 0.16. MOA 0.44 long, front width 0.19, back width 0.41. Chelicerae (Fig. 5D, E View Figure 5 ) with three promarginal and two retromarginal teeth, and a small denticle in-between. Endites (Fig. 5B View Figure 5 ) nearly quadrilateral, longer than wide. Labium (Fig. 5B View Figure 5 ) rectangular, wider than long, anteriorly with strong setae. Sternum oval, anteriorly flattened, as long as wide, covered by very dense setae. Legs measurements (Fig. 5A, B, F View Figure 5 ): I 9.17 (3.09, 1.53, 2.22, 1.55, 0.78); II 6.86 (1.97, 1.14, 2.03, 1.28, 0.44); III 4.67 (1.39, 0.75, 1.31, 0.67, 0.55); IV 5.85 (1.69, 0.73, 1.21, 1.73, 0.49); spination (Fig. 5A, B, F View Figure 5 ): I Ti: d1, v8; Mt: d1, r1, v8; II Ti: d2, v8; Mt: d2, v8; III Pa: d1; cusps: I Fe: 5; Pa: 2; Ti: 3; II Fe: 9; Pa: 3; Ti: 3; IV Fe: 2. Opisthosoma (Fig. 5A, B View Figure 5 ) length 3.14, width 3.87, pentagonal with a notch posteromedially; dorsum covered with sparse peg-like setae; venter with numerous plumose setae medially.

Colouration (Fig. 5A, B View Figure 5 ). Prosoma reddish brown, with radial, irregular, dark brown mottled markings in the surface. Chelicerae, endites, labium, and sternum yellow-brown. Legs yellow to yellow-brown. Opisthosoma white to yellow, with numerous irregular guanine spots; venter yellow, with a few guanine spots on lateral parts.

Epigyne (Fig. 5G, H View Figure 5 ). Epigyne oval, wider than long. Atrium (At) large, inverted heart-shaped, covering 2/3 of epigynal field. Copulatory openings (CO) invisible, hidden by a transverse ridge (TR). Copulatory ducts very short, touching. Membranous sacs (MS) transparent, located anteriorly, covering 2/3 of epigynal plate, slightly separated. Glandular appendages (GA) nearly spherical, almost as long as 1/2 width of spermatheca. Spermathecae (Sp) tube-shaped, slightly separated by less spermathecal width. Fertilisation ducts (FD) slightly less than the length of spermatheca, directed anterolaterally.

Male. Unknown.
