( Figs. 2View FIGURE 2 M, 2 N, 2 O, 3 I, 3 J, 8)

Diagnosis. This species can be distinguished from the other species of the interrupta  group by having the following characters: aedeagus reticulated basally; aedeagal basolateral process broadened, distally with several serrations on dorsal margin ( Fig. 8View FIGURE 8 D).

Description. Ocellar triangle yellowish brown, with 2–6 setae above ocellar setae. Frons yellowish brown. Pedicel yellowish brown; first flagellomere yellow. Clypeus yellowish brown. Postpronotal lobe yellow ( Fig. 2View FIGURE 2 O). Acrostichal setulae in 11–13 irregular rows ( Fig. 2View FIGURE 2 N). Scutellum yellowish brown ( Fig. 2View FIGURE 2 N). Wing ( Fig. 2View FIGURE 2 M): Costal vein between R 2 + 3 and R 4 + 5 distally with 6–7 peg-like spinules on ventral surface. Halter slightly brownish apically. Abdominal tergites black ( Fig. 3View FIGURE 3 I, J); second mostly yellow; third with a pair of yellow patches submedially on anterior margin, yellow laterally; fourth to fifth each with 2 pairs of yellow patches submedially on anterior margin, yellow laterally; sixth with yellow patch posteriorly in holotype, with a pair of yellow patches submedially in one female paratype. Male terminalia: Epandrium with ca. 12 setae near posterior margin and ventral corner per side ( Fig. 8View FIGURE 8 A). Paramere expended and slightly oblong, with distinct wrinkles, lacking sensillum ( Fig. 8View FIGURE 8 C).
