( Figs 1–6 ) Diagnosis. This species is related to S . multidentata from Shennonjia, Hubei, but clearly distinguishable from the latter by the epandrium and aedeagus (in S . multidentata : epandrium broadened on posterior margins, more wider than 3/5 high; aedeagus distinctly expanded submedially and with rhombic opening in ventral view). Description. Male terminalia: Epandrium roundly protruded ventrally, approximately twice as high as wide on posterior margins ( Fig. 1 ). Cercus lacking pubescence ( Fig. 2 ). Surstylus with 8 prensisetae submedially ( Fig. 2 ). Tenth sternite strongly protruded apicolaterally ( Fig. 3 ). Paramere with ca. 5–6 sensilla ( Figs 4, 5 ). Aedeagus with globular projections bearing finely serrated processes basally ( Figs 4, 5 ); nearly oval on opening in ventral view ( Fig. 4 ). Gonopods round apically, not protruded dorsomedially ( Fig. 6 ). Measurements.
