Diagnosis. Paramere curved cucullately, subbasally with several serrations on inner margin ( Fig. 6View FIGURE 6 C); aedeagal basolateral process slender, longer than aedeagus, slightly curved submedially, slightly bifurcated apically ( Fig. 6View FIGURE 6 D).

Description. Ocellar triangle yellow, with 4 setae above ocellar setae. Frons yellow. Pedicel yellowish brown; first flagellomere yellow. Clypeus brown. Postpronotal lobe yellow ( Fig. 2View FIGURE 2 I). Scutellum brownish yellow ( Fig. 2View FIGURE 2 H). Wing ( Fig. 2View FIGURE 2 G): Costal vein between R 2 + 3 and R 4 + 5 distally with 5–7 peg-like spinules on ventral surface. Abdominal tergites dark brown ( Fig. 3View FIGURE 3 G); second mostly yellow; third to fifth each with a pair of yellow patches submedially on anterior margin, yellow laterally; sixth with a small yellow patch medially on anterior margin, yellow laterally.
