( Figs. 8G, 8H View FIGURE 8 , 39 View FIGURE 39 )
Diagnosis. This species is similar to S. (S.) clavispinula Chen & Chen, 2009 in the shape of male terminalia (as figs. 1–7 in Chen & Chen 2009, Fig. 39 View FIGURE 39 ), but can be distinguished from the latter by having the surstylus with 1 peg-like tooth ( Fig. 39B View FIGURE 39 ); the pregonite small, with 3 sensilla ( Fig. 39C, D View FIGURE 39 ); the aedeagus distally broadened in ventral view ( Fig. 39C View FIGURE 39 ).
Description. Male: First flagellomere brown. Clypeus yellow. Mesonotum brown medially, brownish yellow laterally ( Fig. 8G View FIGURE 8 ). Katepisternum yellowish ( Fig. 8H View FIGURE 8 ). Scutellum dark brown ( Fig. 8G View FIGURE 8 ). Halter mostly brown (Fig. Epandrium with ca. 26 setae on dorsal to posterior portions per side ( Fig. 39A View FIGURE 39 ). Surstylus with numerous minute, serrated processes on outer surface and setulae along distal margin ( Fig. 39A, B View FIGURE 39 ). Cercus with much pubescence ( Fig. 39A View FIGURE 39 ). Hypandrium expanded anteromedially ( Fig. 39C, D View FIGURE 39 ). Aedeagal sheath distally slightly dorsad curved and with several minute, serrated processes ( Fig. 39C, D View FIGURE 39 ). Aedeagus with numerous minute, serrated processes distally ( Fig. 39C, D View FIGURE 39 ). Subepandrial sclerite slightly vaulted, rounded distally ( Fig. 39E View FIGURE 39 ).
