Type material.

Holotype ♂ (IZCAS-Ar44529), China: Hainan: Ledong County, Jianfengling National Nature Reserve, Tianchi (18°44.45′N, 108°57.49′E, ca. 860 m), 18.vii.2007, S.Q. Li leg. Paratypes 1♂1♀ (IZCAS-Ar44530-44531), same data as holotype; 1♂1♀ (IZCAS-Ar44532-44533), Jianfengling National Nature Reserve (18°44.38′N, 108°51.06′E, ca. 890 m), 19.vii.2007, C.X. Wang leg.; 1♂1♀ (IZCAS-Ar44534-44535), Lingshui County, Diaoluoshan National Nature Reserve, Direction of the Mysterious Tree (18°43.50′N, 108°52.10′E, ca. 920 m), 18.iv.2011, Y.Y. Zhou leg.; 1♀ (IZCAS-Ar44536), Diaoluoshan Resort (18°43.51′N, 108°52.10′E, ca. 920 m), 20.iv.2011, Y.Y. Zhou leg.

Etymology.

The specific name is after one of the collectors of the type specimens, Ms. Yuanye Zhou; noun (name) in genitive case.

Diagnosis.

The male of Qiongattus yuanyeae sp. nov. resembles that of Chinattus chichila Logunov, 2003 in the general shape of palp, but it can be easily distinguished by the narrow cymbium, which is ~ 3 × longer than wide in ventral view (Fig. 17B ), vs. less than 2 × longer than wide in C. chichila ( Logunov 2003: fig. 1), and by the RTA, which is acutely narrowed distally in retrolateral view (Fig. 17C ), vs. tapered in C. chichila ( Logunov 2003: fig. 2). The female of this species resembles that of Chinattus inflatus Wang & Li, 2020 in having similar basal epigynal plate, but it can be easily distinguished by the presence of spermathecal head and the absence of round structure on basal epigynal plate (Fig. 18A-C ) vs. spermathecae lack heads and basal epigynal plate has round structure in C. inflatus ( Wang and Li 2021: fig. 1A, B).

Description.

Male (Figs 17 , 18D, E, G, H ). Total length 3.94. Carapace 2.00 long, 1.65 wide. Abdomen 1.62 long, 1.32 wide. Clypeus 0.12 high. Eye sizes and inter-distances: AME 0.53, ALE 0.31, PLE 0.29, AERW 1.59, PERW 1.50, EFL 1.03. Legs: I 4.38 (1.23, 0.75, 1.00, 0.95, 0.45), II 3.69 (1.13, 0.65, 0.85, 0.63, 0.43), III 4.04 (1.23, 0.63, 0.88, 0.80, 0.50), IV 4.25 (1.32, 0.60, 0.88, 0.95, 0.50). Carapace red-brown to dark brown, covered with dense pale thin setae, with elevated cephalic region, and sloped thorax; fovea longitudinal, dark, bar-shaped. Chelicerae red-brown, each with two promarginal teeth and one retromarginal tooth. Endites widened distally, the distal half of inner margins paler, bearing dense brown setae. Labium red-brown to dark brown. Sternum slightly longer than wide, with straight anterior margin. Legs yellow to dark brown. Abdomen oval, dorsum grey to dark brown, with transverse, antero-marginal dark stripe, pair of anteromedian muscle depressions followed by pair of mediolateral dark patches; venter coloured as dorsum. Palp (Figs 17A-C , 18E ). Patella longer than wide, with disto-retrolateral bump; tibia ~ 1.5 × longer than wide, with short, inwards curved RTA acutely narrowed to rather pointed tip in retrolateral view; cymbium narrow, ~ 3 × longer than wide in ventral view; bulb elongated, swollen medio-posteriorly, with blunt posterior lobe extending postero-prolaterally; embolus originating the apex of bulb, short, slightly curved medially.

Female (Fig. 18A-C, F ). Total length 4.16. Carapace 2.10 long, 1.81 wide. Abdomen 1.94 long, 1.45 wide. Clypeus 0.12 high. Eye sizes and inter-distances: AME 0.56, ALE 0.32, PLE 0.29, AERW 1.74, PERW 1.64, EFL 1.16. Legs: I 4.44 (1.38, 0.83, 1.05, 0.73, 0.45), II 4.00 (1.25, 0.75, 0.90, 0.65, 0.45), III 4.37 (1.38, 0.65, 0.98, 0.88, 0.48), IV 4.62 (1.43, 0.63, 1.00, 1.03, 0.53). Habitus (Fig. 18F ) similar to that of male, except paler. Epigyne (Fig. 18A-C ). Wider than long, with broad, arc-shaped basal plate; copulatory openings small, medially located, separated from each other ~ 1/3 the basal plate width; copulatory ducts very short, with bar-shaped accessory glands; spermathecae oval, with almost U-shaped heads.

Distribution.

Known only from the type locality in Hainan Island, China.
