description: <i>Paratus nanling</i> Lin &amp; Li, sp. nov. (Figs 20–21, 22B–C, 23) Diagnosis. The new species is similar to <i>P. hamatus</i> Mu &amp; Zhang, 2018 and <i>P. sinensis</i> Marusik, Zheng &amp; Li, 2008 by lacking a conductor, the curved embolus with a thin apex and the long, narrow retrolateral tibial apophysis but can be distinguished by the straightness of the retrolateral tibial apophysis (<i>vs.</i> curved in <i>P.hamatus</i>) and the embolus with serrations (<i>vs.</i> embolus smooth in <i>P.hamatus</i> and <i>P. sinensis</i>). The epigyne is similar to <i>P. sinensis</i> by having a W-shaped plate but can be distinguished by the long copulatory duct that turns almost 180° toward spermatheca (<i>vs.</i> long and V-shaped in <i>P. sinensis</i>) and the copulatory opening is as wide as the diameter of a spermatheca (<i>vs.</i> shorter than the diameter of a spermatheca in <i>P. sinensis</i>). Description. Male (holotype, Figs 22B, 23A). Total length 2.57, carapace 1.29 long, 1.21 wide, abdomen 1.28 long, 1.00 wide. Eye sizes and interdistances: AME 0.12, ALE 0.11, PME 0.10, PLE 0.11, AME–AME 0.06, AME–ALE 0.06, PME–PME 0.09, PME–PLE 0.10, ALE–PLE 0.02. Several bent setae originating at base of fang. Carapace bright yellow, with two pairs of brown bands laterally. Highest point of carapace at fovea. Fovea red brown, long and straight. Cervical groove indistinct, radial groove distinct. Sternum light yellow, with grey pattern submarginally. Chelicerae darker than carapace, with 3 promarginal and 4 retromarginal teeth. Abdomen grey with distinct black patches and irregular white guanine spots. Leg measurements: I 3.96 (1.21, 1.52, 0.79, 0.44), II 3.74 (1.10, 1.41, 0.77, 0.46), III 3.92 (1.08, 1.42, 0.87, 0.55), IV 4.30 (1.25, 1.34, 1.08, 0.63). Legs coloured as carapace, femora III and IV with two distinct black annuli that divide femora into three almost equal parts. Tibiae I and II with 7 pairs of long ventral spines, metatarsi I and II with 3 pairs of long ventral spines. Palp (Fig. 20). Retrolateral tibial apophysis narrowed, straight. Tegulum oval, with triangular tegular outgrowth. Embolus originating at middle of bulb, strongly curved, with serration, terminus with small, narrow apophysis. Female (IZCAS-Ar43270, Figs 22C, 23B). Total length 1.92, carapace 0.92 long, 0.91 wide, abdomen 1.04 long, 0.77 wide. Eye sizes and interdistances: AME 0.11, ALE 0.10, PME 0.09, PLE 0.11, AME–AME 0.07, AME–ALE 0.05, PME– PME 0.10, PME–PLE 0.11, ALE–PLE 0.02. Leg measurements: I 3.82 (1.13, 1.57, 0.74, 0.38), II 4.13 (1.22, 1.60, 0.85, 0.46), III 4.25 (1.31, 1.44, 1.00, 0.50), IV 4.76 (1.35, 1.45, 1.36, 0.60). Other characters as in male except darker colour and slightly larger body size. Epigyne (Fig. 21). Epigynal plate weakly sclerotized, with W-shaped posterior margin, without wrinkles. Copulatory opening hidden under epigynal plate. Copulatory duct long, V-shaped. Spermathecae spherical, separated by about 3 times spermatheca diameter. Fertilization duct curved dorsally, longer than radius of spermatheca. Material examined. Holotype &amp;male; (IZCAS-Ar43268), China: Guangdong, Shaoguan City, Nanling (24.9288°N, 113.0159°E), 23 August 2021, Q. Lu leg. Paratypes. 1&amp;male; 1&amp;female; (IZCAS-Ar43269, Ar43270), same data as holotype. Distribution. Known only from the type locality. Etymology. The specific name is a noun in apposition taken from the type locality.
