Figs 18–19 , 62 urn:lsid:zoobank.org:act: D33E3AA5-0D26-42CD-ABC3-D44F0B25D2A7 Type material. Holotype male: CHINA : Guangxi Province : Nanning City , Wuming County , Damingshan National Nature Reserve , 23.53°N , 108.37°E , 603 m , native forest, 27 May 2017 , Y. Zhong leg. (CBEE). Paratype : 1 male , with same data as holotype ( CBEE ) . Etymology. The specific name is derived from the Latin adjective curvus , - a , - um , meaning “curved” referring to the tip of embolic apophysis being curved. Diagnosis. The males of this new species can be separated from other Sinopoda species by the male palp with unique “U”-shape of the RTA in retrolateral view ( Figs 18 A–C, 19A–D). Description.

Measurements of palp and legs: Palp 10.0 (3.5, 1.2, 1.6, –, 3.7); I 29.0 (7.7, 3.4, 7.2, 8.1, 2.6); II 30.4 (8.4, 2.9, 8.1, 8.3, 2.7); III 23.5 (7.2, 2.7, 5.9, 5.9, 1.8); IV 26.0 (7.5, 2.4, 6.5, 7.3, 2.3). Leg formula: II-I-IV-III. Cheliceral furrow with 3 anterior, 4 posterior teeth and ca. 22 denticles. Palp as in diagnosis. Cymbium distinctly longer than tibia. Embolus arising from tegulum at 7:30 to 8-o’clockposition. Tip of embolic apohysis wide, significantly curved and membranous distally. Tegulum partly covering proximal part of embolus. Spermophor distinctly curved in ventral view. RTA arising medially to proximally from tibia, with the dRTA straight in ventral view, undulating in retrolateral view, with the vRTA triangular in retrolateral view ( Figs 18 A–C, 19A–D). Colouration in ethanol. Dorsal prosoma yellowish-brown, with broad dark lateral bands and yellow submarginal transversal light band posteriorly. Fovea and radial furrows slightly marked. Labium and gnathocoxae yellowish-brown, both with distal parts brighter. Sternum yellowish-brown, with margin brown. Chelicerae brown with 2 longitudinal stripes. Legs yellowish-brown with dark spots. Dorsal opisthosoma yellowish-brown, covered by brown hairs, with three pairs of dark patches laterally. Ventral opisthosoma yellowish-brown with irregular pattern ( Figs 19 E–F). Distribution. China ( Guangxi ) ( Fig. 62 ).
