Diagnosis. This species is similar to S. crassitarsa and S. longituba in having similar body size ( Figs 1–6 ), cusps on metatarsus I and tarsus I ( Figs 12, 14 ), anterolateral extension of carapace and pit, tubercle on chelicerae ( Figs 11, 13 ), males of this species have a similar complicated apophysis on the patella in palp and similar location of the embolus on the genital bulb, but can be distinguished from the latter by: 1) basal retrolateral patellar apophysis of male palp proximately as long as cymbium in retrolateral view, longer than that in S. crassitarsa , but shorter than that in S. longituba ( Figs 27, 29–31, 33 ); 2) the much larger and nontransparent dorsal scutum in S. wuyi ( Figs 3, 6 ); 3) patella of male palp with dentigerous apophysis versus absent in S. wuyi ; 4) leg I of S. longituba stonger than that of S. wuyi . Females are similar to S. longituba , but differ in: 1) spermathecae calabash-shaped versus round in S. longituba ( Figs 20–26 ); 2) copulatory ducts folded versus spiral in S. longituba ( Figs 20–26 ).

Sternum 0.50 long, 0.38 wide. Thoracic region modified with semiround pits, rugose at posterior margin; cephalic pars distinctly raised, smooth, slightly lower than in male. Abdomen fawn, patch different from that of male, with brown stain, abdominal dorsal scutum absent ( Figs 1, 5 ).

Chelicerae brown, bearing a small proximal tubercle on anterior surface, with one proximal and two adnate promarginal teeth, and a few long plumose setae distally close to fang, with long setae on frontal © Zoological Systematics , 39 (2): 236–247 surface ( Figs 11 , 15–16 ). Labium brown, wider than long, Labral spur large, porrect ( Figs 7–8 ). Legs yellowish-brown, femoral cuticle granulated. Leg measurements: I 2.96 (1.00, 0.25, 0.73, 0.38, 0.60); II 2.31 (0.78, 0.15, 0.55, 0.28, 0.55); III 1.84 (0.58, 0.15, 0.40, 0.28, 0.43); IV 2.21 (0.70, 0.20, 0.53, 0.28, 0.50). Leg formula: I-II-IV-III. Leg I longest and robust, and with four short cusps on ventral metatarsus and tarsus ( Fig 12 ). Ventral scutum modified with tiny stripes ( Fig 5 ), and a pair of retrolateral corners. Book lung covers large, longer than wide ( Figs 19–21, 23–25 ). An annular sclerotized plate closely surrounding the spinnerets ( Fig 2 ). Spermathecae calabash-shaped, strongly sclerotized. Fertilization ducts long and sinuous, arising from the bottom of spermathecae. Copulatory ducts long, twisty, opening at the posterior margin of epigynal area ( Figs 20–26 ). Fig. 34. Distribution records of Sinanapis wuyi Jin & Zhang, 2013 . Male. Total length 2.13. Cephalothorax 1.03 long, 0.75 wide, 1.05 high. Abdomen 1.10 long, 1.03 wide, 1.43 high. Carapace red-brown. Cephalothorax same as in female, but with two setae on midline and two setae behind PLE, with six processes. Clypeus 0.40 high. Gnathochilarium and sternum reddish-brown, sternum 0.63 long, 0.50 wide. Eye pattern same as in female. ALE> PLE> PME> AME in size.

Labium and leg chaetotaxy are same as in female ( Figs 9, 10 ). Leg measurements: I 3.65 (1.26, 0.33, 0.93, 0.43, 0.70), II 2.38 (0.80, 0.15, 0.70, 0.28, 0.45), III 1.86 (0.53, 0.15, 0.45, 0.28, 0.45), IV 2.19 (0.70, 0.20, 0.58, 0.28, 0.43). Leg formula: I-II-IV-III. Abdomen spherical. Dorsal scutum sub-circular,, cuticle faintly granulate anteriorly, covered with bushy short setae. Ventral scutum small, closely surrounding pedicel ( Figs 3, 6 ). Spinnerets encircled with a sclerotized plate ( Fig 4 ). Male palp relatively large, yellowish-brown. Palpal patella structure complex, with three apophyses, one retrolaterally longest and hook like, two prolaterally shorter ( Figs 27–33 ). Palpal tibia with a few long setae and a bulge, but without apophysis. Cymbium hemispherical, covered with long setae ( Figs 27–33 ). Bulb simple, concave, without apophysis. Tegulum smooth and flat. Embolus long, strongly sclerotized, distally filiform. Conductor absent. ( Fig 28 ). Distribution. China ( Jiangxi , Hunan , Fujian ).
