(Figs 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 C); katepisternum and mesopleuron brownish yellow, each with brown patches (Fig. 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 G), sometimes with unapparent, brown longitudinal stripes (Fig. 8 H). Postpronotal lobe yellow (Fig. 8 I). Acrostichal setulae in 13–15 irregular rows (Fig. 8 G, H). Scutellum yellowish brown to dark brown, pale at tip (Fig. 8 G, H). Pleura with a brown, longitudinal stripe above (Fig. 8 I). Wing (Fig. 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 H). Abdominal tergites brown to black, mostly with yellow patches (Fig. 11 I–K). Male terminalia: Epandrium with pubescence and 5 setae near posterior and ventral margin per side (Fig. 33 A). Paramere broad, with 7 sensilla distodorsally and small process apically (Fig. 33 C). Aedeagus thick, with pubescence distally (Fig. 33 D).
