Diagnosis. This species is similar to S. crassitarsa and S. longituba in having similar body size ( Figs 1–6 View Figs 1–6 ), cusps on metatarsus I and tarsus I ( Figs 12, 14 View Figs 11–14 ), anterolateral extension of carapace and pit, tubercle on chelicerae ( Figs 11, 13 View Figs 11–14 ), 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 View Figs 27–30 View Figs 31–33 ); 2) the much larger and nontransparent dorsal scutum in S. wuyi ( Figs 3, 6 View Figs 1–6 ); 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 View Figs 20–23 View Figs 24–26 ); 2) copulatory ducts folded versus spiral in S. longituba ( Figs 20–26 View Figs 20–23 View Figs 24–26 ).
