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.
