Frons yellowish in male, yellow to brown in female. Pedicel yellowish in male, yellow to brownish in female; first flagellomere yellowish in male, yellow in female. Clypeus brownish medially, brown laterally. Palpus brownish. Mesonotum yellow in female ( Fig. 3C). Postpronotal lobe yellowish in male ( Fig. 3B), yellow in female ( Fig. 3D). Acrostichal setulae in ca. 8–10 irregular rows ( Fig. 3A, C). Scutellum brownish, black laterally and yellowish at tip in female ( Fig. 3C). Pleura, katepisternum and meron yellowish to yellow ( Fig. 3B, D). Wing ( Fig. 2A): Costal vein between R2+3 and R4+5 distally with ca. 6–7 peg-like spinules on ventral surface. Only 4th and 5th abdominal tergites with black patches in male ( Fig. 5A–C); all abdominal tergites with black patches in female ( Fig. 5D). Male terminalia: Epandrium pubescent near posterior margin, with ca. 9 setae near posterior margin and ventral corner per side ( Fig. 6B). Paramere slender, narrowed basally and apically, with ca. 5 sensilla distally ( Fig. 6D).   FIGURE 6.  Leucophenga argentatade Meijere, 1914, male head and terminalia in lateral view. A.
