Description.

Male and female: Head (Fig. 7A ): frons brownish with a brown band anteriorly. Pedicel brown; first flagellomere yellowish. Facial carina yellowish brown, short, as 1/3 length as face.

Thorax (Fig. 7B, C ): mesonotum yellowish brown, with four brown longitudinal stripes. Acrostichal setulae in ca. 10-12 irregular rows. Scutellum yellowish brown, dark brown near basal scutellar setae, pale at tip. Pleura dark brown.

Male terminalia (Fig. 16A-D ): epandrium with ca. 17 setae near posterior and ventral margins per side. Surstylus with six peg-like prensisetae. Hypandrium with a pair of paramedian setae and pubescence medially. Paramere with seven sensilla medially and pubescence distally. Aedeagus with pubescence ventrally.

Female terminalia (Fig. 16E ): oviscapt with one subapical trichoid ovisensillum, 16, 11 and 5 peg-like ovisensilla per side on ventral, dorsal and apical margins, respectively.
