( Figs 3 View FIGURE 3 H, 8G–I, 11I –K, 16A, 16B, 33)

Diagnosis. This species is similar to L. multipunctata in the male terminalia, but can be distinguished from the latter by having the paramere slightly broadened and small process apically ( Fig. 33 View FIGURE 33 C); katepisternum and mesopleuron brownish yellow, each with brown patches ( Fig. 8 View FIGURE 8 I).

Description. Ocellar triangle dark brown, with 2–5 setae above ocellar setae. Frons brownish to brown. Pedicel yellowish brown; first flagellomere yellow. Clypeus brown. Palpus brownish. Mesonotum brownish yellow to brown ( Fig. 8 View FIGURE 8 G), sometimes with unapparent, brown longitudinal stripes ( Fig. 8 View FIGURE 8 H). Postpronotal lobe yellow ( Fig. 8 View FIGURE 8 I). Acrostichal setulae in 13–15 irregular rows ( Fig. 8 View FIGURE 8 G, H). Scutellum yellowish brown to dark brown, pale at tip ( Fig. 8 View FIGURE 8 G, H). Pleura with a brown, longitudinal stripe above ( Fig. 8 View FIGURE 8 I). Wing ( Fig. 3 View FIGURE 3 H): Costal vein between R2+3 and R4+5 distally with 5–8 peg-like spinules on ventral surface, and broad, brownish band diastally ( Fig. 3 View FIGURE 3 H). Abdominal tergites brown to black, mostly with yellow patches ( Fig. 11 View FIGURE 11 I–K). Male terminalia: Epandrium with pubescence and 5 setae near posterior and ventral margin per side ( Fig. 33 View FIGURE 33 A). Paramere broad, with 7 sensilla distodorsally and small process apically ( Fig. 33 View FIGURE 33 C). Aedeagus thick, with pubescence distally ( Fig. 33 View FIGURE 33 D).
