( Figs 2C View FIGURE 2 , 6 View FIGURE 6 )

Diagnosis. This species resembles S. toyaensis Okada & Sidorenko, 1992 in some characters of the male terminalia, but can be distinguished by the mesonotum dark brown, with 1 thin, unconspicuous, yellow longitudinal stripe medially, yellowish brown laterally ( Fig. 2C View FIGURE 2 ); aedeagus slightly flat apically in ventral view ( Fig. 6C, D View FIGURE 6 ). The minimum interspecific genetic distance to S. toyaensis is 3.5%, which is smaller than to other species ( Table 2).

Description. Male: Frons black. First flagellomere yellow on basal 2/3, black on distal 1/3. Clypeus and palpus yellow. Katepisternum entirely white. Scutellum black ( Fig. 2C View FIGURE 2 ). Femur of foreleg with 4 long erect setae near distal part of posteroventral surface. Abdominal tergites dark brown to black ( Fig. 2C View FIGURE 2 ). Male terminalia ( Fig. 6 View FIGURE 6 ): Epandrium slightly protruded ventrally, with numerous setae on posterior portion per side. Surstylus with numerous setulae basally. Cercus lacking pubescence. Tenth sternite broadened, with 1 pair of processes submedially. Paramere with 1 setula.
