( Figs 2 View FIGURE 2 I, 5G, 5H, 8J, 11G, 11H, 22)
Diagnosis. This species differs from the other species in having the epandrium without setae near ventral corner ( Fig. 22 View FIGURE 22 A); aedeagus broadened and slightly spatulate distally in lateral view ( Fig. 22 View FIGURE 22 D).
Description. Ocellar triangle dark brown, with ca. 3 setae above ocellar setae. Frons brown. Pedicel yellow; first flagellomere yellowish brown. Clypeus dark brown. Mesonotum mostly yellowish brown, dark brown before scutellum ( Fig. 5 View FIGURE 5 G). Postpronotal lobe slightly yellow. Acrostichal setulae in ca. 14 irregular rows ( Fig. 5 View FIGURE 5 G). Scutellum brown medially, dark brown laterally, pale at tip ( Fig. 5 View FIGURE 5 G). Katepisternum yellow, with brownish patch above ( Fig. 5 View FIGURE 5 H). Meron yellow ( Fig. 5 View FIGURE 5 H). Wing ( Fig. 2 View FIGURE 2 I): Costal vein between R2+3 and R4+5 distally with ca. 6 peg-like spinules on ventral surface. Abdominal tergites brown to dark brown ( Fig. 8 View FIGURE 8 J); second yellow anteriomedially, with a patch near lateral margin; third and fourth each with a pair of narrow, yellow patches submedially along anterior margins; fifth sometimes with a pair of small yellow patches submedially along anterior margin; sixth with narrow, yellow band on posterior margin. Male terminalia: Epandrium with ca. 9 setae near dorsal to posterior margin per side ( Fig. 22 View FIGURE 22 A). Hypandrium lacking sensillum ( Fig. 22 View FIGURE 22 B). Paramere narrow and slightly curved, with ca. 3 sensilla and pubescence distally ( Fig. 22 View FIGURE 22 C).
