The specific name is after the holotype locality, Yinggeling National Nature Reserve; noun (name) in apposition. Diagnosis. Spiralembolus yinggeling sp. nov. resembles that of S. yui sp. nov. in having similar habitus and copulatory organs, but it can be easily distinguished by the following: (1) the embolus is spiralled into less than three coils (Fig. 19B ), vs. more than four coils in S. yui (Fig. 21B ); (2) the RTA is tapered in retrolateral view (Fig. 19C ), vs. acutely narrowed postero-medially in S. yui (Fig. 21C ); (3) the copulatory ducts ca. half the spermathecal width, and connected to the postero-inner portions of spermathecae (Fig. 20B ), vs. ~ 1/4 the spermathecal width, and connected to the antero-inner portions of spermathecae in S. yui (Fig. 22B ).

Scale bars: 0.1 mm ( A-C, H ); 0.5 mm ( D-G ). Description. Male (Figs 19 , 20D, E, G, H ). Total length 3.20. Carapace 1.76 long, 1.36 wide. Abdomen 1.40 long, 1.10 wide. Clypeus 0.07 high. Eye sizes and inter-distances: AME 0.40, ALE 0.26, PLE 0.22, AERW 1.36, PERW 1.28, EFL 0.80. Legs: I 3.26 (1.00, 0.55, 0.80, 0.53, 0.38), II 2.82 (0.90, 0.48, 0.63, 0.43, 0.38), III 3.24 (1.03, 0.48, 0.75, 0.63, 0.35), IV 3.57 (1.08, 0.48, 0.80, 0.83, 0.38). Carapace red-brown to dark, almost square, covered with thin setae on cephalic region, with cluster of white setae on clypeus, and oblique, dark brown stripes on thorax; fovea longitudinal, dark, linear. Chelicerae dark yellow to red-brown, each with two promarginal teeth and one retromarginal tooth. Endites almost square, with paler inner margins bearing brown setae. Labium tapered, bearing several dark setae on paler distal portion. Sternum almost oval, yellow-brown, and covered with dark setae. Legs yellow to dark brown, bearing dense dark brown ventral setae on tibiae I and clusters of white setae on femora and tibiae. Abdomen oval, dorsum dark brown, covered with white and dark setae and anteromedian scutum, with irregular pale-yellow patches medially and transverse, pale stripes posteriorly; venter dark brown, covered with short dark brown setae, with pair of mediolateral pale patches. Palp (Figs 19A-C , 20E ). Tibia short, covered with dense white, long setae dorsally, with tapered RTA curved towards ventral side medially and blunt apically; cymbium ~ two times longer than wide, covered with dense, long, white setae on the dorsum of proximal half; bulb swollen; sperm duct strongly curved retrolaterally; embolus originates from the antero-prolateral portion of bulb, spiralled into less than three coils, with rather pointed tip. Female (Fig. 20A-C, F ). Total length 3.68. Carapace 1.56 long, 1.20 wide. Abdomen 1.98 long, 1.54 wide. Clypeus 0.08 high. Eye sizes and inter-distances: AME 0.39, ALE 0.24, PLE 0.22, AERW 1.24, PERW 1.17, EFL 0.78. Legs: I 3.13 (0.95, 0.55, 0.75, 0.50, 0.38), II 2.90 (0.93, 0.48, 0.63, 0.48, 0.38), III 3.36 (1.05, 0.50, 0.78, 0.60, 0.43), IV 3.79 (1.08, 0.50, 0.88, 0.80, 0.53). Habitus (Fig. 20F ) similar to that of male except paler, without dense dorsal white and dark setae, and the dorsal scutum on the abdomen, the cluster of white setae on clypeus, and clusters of white setae on femora and tibiae of legs. Epigyne (Fig. 20A-C ). Wider than long; copulatory openings round, anteromedially located, separated from each other ~ 1.5 x equal to their width; copulatory ducts thick, inner to spermathecae, close to each other, strongly curved anteromedially, and connected to the posterior portions of spermathecae; spermathecae almost oval, ~ 2 x wider than copulatory ducts; fertilization ducts originate from the most antero-inner portions of spermathecae, transversely extending. Distribution. Known only from the type locality in Hainan Island, China.
