Paramere distally broadened and pubescent in lateral view (Fig. 10D ); gonopods roundly expanded dorsally in lateral view (Fig. 10D ). The 5.3% interspecific genetic distance to S. scutellimargo is one of the smallest interspecific distances ascertained within this group (Table 2 ). Description. Male and female: Head (Fig. 4A ): frons yellowish brown. Pedicel brownish; first flagellomere yellowish. Facial carina yellowish, short, as 1/3 length as face. Thorax (Fig. 4B, C ): mesonotum brown, with three yellowish brown longitudinal stripes. Acrostichal setulae in ca. 8-10 irregular rows. Scutellum yellowish, dark brown near basal scutellar setae, pale at tip. Pleura brownish to brown. Abdomen (Fig. 4D ): all tergites yellow with dark brown caudal bands, the caudal band on tergite II narrowed medially. Male terminalia (Fig. 10A-D ): epandrium with ca. 16 setae near posterior and ventral margins per side. Surstylus with eight peg-like prensisetae. Hypandrium with a pair of paramedian setae and pubescence basomedially. Paramere with eight sensilla medially distally. Aedeagus lacking pubescence. Female terminalia (Fig. 10E ): oviscapt with one subapical trichoid ovisensillum, 17, 14 and 5 peg-like ovisensilla per side on ventral, dorsal and apical margins, respectively.
