( Figs. 2 View FIGURE 2 L, 5C, 5D, 9B, 9C, 20)

Diagnosis. This species is mostly similar to L. nigroscutellata in having the wing fuscous along R1 and costa ( Fig. 2 View FIGURE 2 D, L), the shape of paramere ( Figs. 13 View FIGURE 13 , 20 View FIGURE 20 C), and the aedeagus ventrolaterally with a thin process bearing a sensillum at tip ( Figs. 13 View FIGURE 13 , 20 View FIGURE 20 D), but can be distinguished from the latter by the color patterns of abdominal tergites in both male ( Fig. 9 View FIGURE 9 B) and female ( Fig. 9 View FIGURE 9 C), and the aedeagus acute apically ( Fig. 20 View FIGURE 20 D).

Description. Ocellar triangle dark brown, with ca. 0–2 seta(e) above ocellar setae. Frons brownish yellow to brownish, with an indistinct, brownish, longitudinal stripe medially. Pedicel brownish yellow to brownish; first flagellomere yellow. Clypeus brown. Palpus brownish yellow to brownish. Mesonotum brownish, mostly with three broad, dark brown, longitudinal stripes medially and laterally in male ( Fig. 5 View FIGURE 5 C), brownish yellow, brownish before scutellum in female. Postpronotal lobe yellow to brownish yellow ( Fig. 5 View FIGURE 5 D). Acrostichal setulae in ca. 6–8 irregular rows ( Fig. 5 View FIGURE 5 C). Scutellum dark brown, brownish at tip in male ( Fig. 5 View FIGURE 5 C), brownish yellow at tip in female. Pleura, katepisternum and meron mostly brown above ( Fig. 5 View FIGURE 5 D). Wing ( Fig. 2 View FIGURE 2 L): Costal vein between R2+3 and R4+5 distally with ca. 4–7 peg-like spinules on ventral surface. Midleg obviously brown on knees. Abdominal tergites brown, 2nd to 4th tergites each with a pair of yellow patches submedially in male ( Fig. 9 View FIGURE 9 B), entirely brown in female ( Fig. 9 View FIGURE 9 C). Male terminalia: Epandrium with ca. 3 setae near posterior margin per side ( Fig. 20 View FIGURE 20 A). Surstylus rounded apically ( Fig. 20 View FIGURE 20 A). Hypandrium with 1 sensillum ( Fig. 20 View FIGURE 20 B). Paramere with ca. 6 sensilla distally ( Fig. 20 View FIGURE 20 C).

Distribution. China (Yunnan).

Etymology. A combination of the Latin words “ fuscus ” (= brown) + “ pedes ” (= leg), referring to the leg obviously brown on knees.
