Etymology. The species epithet is derived from the type locality, Nonggang National Reserve, Guangxi, China.

Diagnosis. The male of the new species resembles that of Hyptiotes dentatus Wunderlich 2008 in having two tegular apophyses, and a very long embolus circling around the bulb for more than one circle but can be distinguished from each other by different positions of origin of embolus and different shapes of tegular apophyses 2 (TE2) and terminal apophyses (TA): embolus approximately originated from the seven o’clock and so can be seen in the prolateral view of palpal organ in the new species ( Figs 4A View FIGURE 4 , 5A View FIGURE 5 ), while embolus approximately originated at the nine o’clock (the right palp described in Wunderlich, 2008) and can be seen in the prolateral view of palpal organ in H. dentatus ( Wunderlich 2008: fig. 9); TE2 extended flat, extending transversely in the new species ( Figs 4C View FIGURE 4 , 5C View FIGURE 5 ), while TE2 slender, extending longitudinally in H. dentatus ( Wunderlich 2008: figs 8, 9); TA highly sclerotized, like an macrosetae in the new species ( Figs 4C View FIGURE 4 , 5C View FIGURE 5 ), while TA wide and flat, membranous and translucent in H. dentatus ( Wunderlich 2008: figs 8, 9). The male of the new species also resembles that of H. paradoxus but can be distinguished easily from each other by median apophysis (MA) and TE2: MA with a wide apical part in new species ( Figs 4C View FIGURE 4 , 5C View FIGURE 5 ), while with a narrow apical part in H. paradoxus ( Figs 12C View FIGURE 12 , 13C View FIGURE 13 ). TE2 with only one end in new species ( Figs 4C View FIGURE 4 , 5C View FIGURE 5 ), while with two ends in H. paradoxus ( Figs 12C View FIGURE 12 , 13C View FIGURE 13 ). The female of the new species resembles that of Hyptiotes gerhardti Wiehle 1929 in having similar receptacula (R), and long and twisted copulatory ducts (CD), but can be distinguished from each other by the number of loops of accessory glands (AG) and the developed degrees of median ridge (MR), AG twisted to form at least 7 regular loops around receptaculum in the new species ( Figs 8B View FIGURE 8 , 9B View FIGURE 9 ), while AG twisted, but not to form regular loops in H. gerhardti ( Wunderlich 2017: fig. 14). MR weak in the new species ( Fig. 8C View FIGURE 8 ), while MR developed in H. gerhardti ( Wunderlich 2017: figs 13, 14). The obvious difference between the females of new species and H. paradoxus is that MR of the new species is inconspicuous ( Fig. 8C View FIGURE 8 ), while that of the latter is distinct ( Fig. 16C View FIGURE 16 ).

Description. Male. Total length 2.83, carapace 1.08 long, 1.13 wide, abdomen 2.58 long, 2.04 wide. Carapace deep brown, nearly triangular, narrow anteriorly, and sparsely covered with plumose setae. Clypeus slightly light in color, with two brown longitudinal strips in front of ALE (The position pointed by the red arrows in Figs 2A View FIGURE 2 , 3A View FIGURE 3 ). Eye area strongly elevated. Fovea wide and deep. Eight eyes are present, but ALE degenerated, only dark red marks remained. Posterior border of MOA about six times of the anterior border in width.

Labium triangular. Sternum yellow, shield-shaped, with a posterior hump ( Fig. 2B View FIGURE 2 ). Legs brown dorsally and yellowish ventrally, bearing many strong bristles ( Fig. 2A, B View FIGURE 2 ).

Leg measurements: I 3.49 (1.18, 0.36, 0.81, 0.84, 0.3); II 2.44 (0.87, 0.31, 0.32, 0.67, 0.27); III 2.06 (0.67, 0.21, 0.31, 0.53, 0.34); IV 2.70 (0.83, 0.37, 0.55, 0.67, 0.28). Abdomen oval, light yellow, covered with short setae and plumose setae, and dorsally with irregular dark spots and two rows of white dots in the middle line; ventrally, anterior spinnerets much larger than others. Cribellum wide, close to spinnerets. ( Figs 2B, C View FIGURE 2 ; 3B View FIGURE 3 ).

Palp ( Figs 4 View FIGURE 4 , 5 View FIGURE 5 ). Terminal apophysis sclerotized and bending towards prolateral side. Median apophysis strong, highly sclerotized, with the apical part rolled towards both base and venter. Tegular apophysis 1 membranous, transversely extending and slightly twisting. Tegular apophysis 2 strong sclerotized, transversely extending, with a slender apical end bending towards base. Conductor consisting of two parts: one part with a strong sclerotized apical part; the other part membranous, gradually becoming narrow. Embolus extremely long, with the original point be seen in the prolateral side. Cymbium long and narrow, with numerous of long setae. Patella and tibia with a strong bristle each and tibia also with a tuft of neat and long setae.

Female: Total length 3.25, carapace 1.14 long, 1.17 wide, abdomen 2.58 long, 2.04 wide. Carapace light brown. Eye diameters: AME 0.08, PME 0.13, PLE 0.2, AME-AME 0.05, AME-PME 0.21, PME-PME 0.76, PME-PLE 0.13, PLE-PLE 1.2 ( Figs 1A, C View FIGURE 1 ; 2A View FIGURE 2 ). Leg measurements: I 3.49 (1.18, 0.36, 0.81, 0.84, 0.3); II 2.44 (0.87, 0.31, 0.32, 0.67, 0.27); III 2.06 (0.67, 0.21, 0.31, 0.53, 0.34); IV 2.70 (0.83, 0.37, 0.55, 0.67, 0.28). The other features of cephalothorax and legs resemble those of the male ( Figs 6 View FIGURE 6 , 7A View FIGURE 7 ). Abdomen oval, with middle area projecting upwards ( Fig. 6C View FIGURE 6 ). White patches covering throughout abdomen ( Fig. 6 View FIGURE 6 ). Anterior spinnerets much larger than others. Cribellum close to spinnerets and relatively larger than that of male ( Figs 6B View FIGURE 6 , 7B View FIGURE 7 ).

Copulatory duct sclerotized and twisted. Accessory glands twisting around the receptaculum to form seven loops. Receptaculum spherical.
