Pedicel yellowish in male, yellow in female; first flagellomere yellow. Clypeus brownish yellow. Palpus brownish yellow. Postpronotal lobe yellowish in male (Fig. 4 D), yellow in female (Fig. 4 F). Acrostichal setulae in ca. 8–10 irregular rows (Fig. 4 C, E). Scutellum brown, dark brown laterally and yellowish at tip in male (Fig. 4 C), brownish yellow, dark brown laterally and yellow at tip in female (Fig. 4 E). Pleura, katepisternum and meron yellow to yellowish (Fig. 4 D, F). Wing (Fig. 2 D): Costal vein between R2+3 and R4+5 distally with ca. 4–7 peg-like spinules on ventral surface. All abdominal tergites with brown to black patches in both male and female (Fig. 5 J–L). Male terminalia: Epandrium pubescent medially and near posterior margin, with ca. 5 setae near posterior margin and ventral corner per side (Fig. 9 A). Paramere triangular, narrowed apically, with ca. 2 sensilla submedially (Fig. 9 C).
