Specimens examined. CHINA : 1♂ , 1♀ (SCAU, Nos 128246, 47), Nonggang , Chongzuo , Guangxi , 25°00'N , 106°51'E , alt. 230 m , 21-24.viii.2004 , HW Chen . Diagnosis. This species is very similar to S. scutellimargo in the patterns of abdominal tergites (Fig. 3H ) and aedeagus curved dorsal (Fig. 9D ), but can be distinguished from the latter by having the paramere slightly broadened distally in lateral view (Fig. 9D ); gonopods elliptically expanded dorsally in lateral view (Fig. 9D ); see under that species. Description. Male and female: Head (Fig. 3E ): frons yellowish brown with a brown band anteriorly. Pedicel brownish; first flagellomere yellowish. Facial carina yellowish brown. Thorax (Fig. 3F, G ): mesonotum yellowish brown, with a brown longitudinal stripe on 1/3 posterior. Acrostichal setulae in ca. 8-10 irregular rows. Scutellum brownish, dark brown near basal scutellar setae, pale at tip. Pleura dark brown. Abdomen (Fig. 3H ): tergites II to V yellow, with dark brown caudal bands, the caudal band on tergite II narrowed medially; tergite VI entirely dark brown. Male terminalia (Fig. 9A-D ): epandrium with ca. 15 setae near posterior and ventral margins per side. Surstylus with 6-7 peg-like prensisetae. Hypandrium with a pair of paramedian setae and pubescence basomedially. Paramere with 12 sensilla, and a small projection basally. Aedeagus lacking pubescence. Female terminalia (Fig. 9E ): oviscapt with one subapical trichoid ovisensillum, 14, 8 and 5 peg-like ovisensilla per side on ventral, dorsal and apical margins, respectively.
