( Figs. 2 View FIGURE 2 B, 3E–H, 5E, 5F, 7)
Diagnosis. This species resembles L. argentata in having the mesonotum and scutellum entirely yellowish in male ( Fig. 3 View FIGURE 3 A, E), and in the color patterns of abdominal tergites in female ( Fig. 5 View FIGURE 5 D, F), but can be distinguished from the latter by having the paramere nearly triangular ( Fig. 7 View FIGURE 7 C), and the aedeagus distolaterally with two acute processes each bearing a sensillum at tip ( Fig. 7 View FIGURE 7 D).
Description. Ocellar triangle brown, with ca. 0–2 setae above ocellar setae. Frons yellowish to yellow in male, yellow in female. Pedicel yellowish in male, yellow in female; first flagellomere yellow. Clypeus brownish. Palpus brownish. Mesonotum brownish yellow in female ( Fig. 3 View FIGURE 3 G). Postpronotal lobe yellowish in male ( Fig. 3 View FIGURE 3 F), yellow in female ( Fig. 3 View FIGURE 3 H). Acrostichal setulae in ca. 8–10 irregular rows ( Fig. 3 View FIGURE 3 E, G). Scutellum brownish, black laterally and yellow at tip in female ( Fig. 3 View FIGURE 3 G). Pleura, katepisternum and meron yellow to yellowish ( Fig. 3 View FIGURE 3 F, H). Wing ( Fig. 2 View FIGURE 2 B): Costal vein between R2+3 and R4+5 distally with ca. 6–8 peg-like spinules on ventral surface. Third to 6th abdominal tergites with black patches in male ( Fig. 5 View FIGURE 5 E); all abdominal tergites with black patches in female ( Fig. 5 View FIGURE 5 F). Male terminalia: Epandrium pubescent medially and near posterior margin, with ca. 7 setae near posterior margin and ventral corner per side ( Fig. 7 View FIGURE 7 A). Paramere narrowed basally and apically, with ca. 1 sensillum submedially and ca. 4 ones distally ( Fig. 7 View FIGURE 7 C).
