( Figs 3 View FIGURE 3 B, 6C, 6D, 9A, 12C, 12D, 25)

Diagnosis. This species is similar to L. todai in the patterns of abdominal tergites and the shaped of aedeagus, but can be distinguished from the latter by having the wing with distinct dark patch basally ( Fig. 3 View FIGURE 3 B); the katepisternum yellow ( Fig. 6 View FIGURE 6 D).

Description. Ocellar triangle dark brown, with ca. 3 setae above ocellar setae. Frons yellowish brown. Pedicel yellowish brown; first flagellomere yellow. Clypeus brown. Mesonotum yellowish brown medially, brown laterally and near scutellar sutere ( Fig. 6 View FIGURE 6 C). Postpronotal lobe yellow. Acrostichal setulae in ca. 12–14 irregular rows ( Fig. 6 View FIGURE 6 C). Scutellum dark brown, yellow at tip ( Fig. 6 View FIGURE 6 C). Katepisternum and meron mostly yellow ( Fig. 6 View FIGURE 6 D). Wing ( Fig. 3 View FIGURE 3 B): Costal vein between R2+3 and R4+5 distally with ca. 7–8 peg-like spinules on ventral surface. Abdominal tergites dark brown ( Fig. 9 View FIGURE 9 A); second brown subanterolaterally and posteriorly; third with a pair of narrow, yellow patches submedially along anterior margin; fourth and fifth with 2 pairs of yellow patches submedially along or near anterior margins; sixth with M-shaped yellow patch medially. Male terminalia: Epandrium with ca. 18 setae near dorsal margin to ventral corner per side ( Fig. 25 View FIGURE 25 A). Hypandrium lacking sensillum ( Fig. 25 View FIGURE 25 B). Paramere pubescent and with ca. 2 sensilla submedially ( Fig. 25 View FIGURE 25 C). Aedeagus reticulated, distally round and curved ventrad ( Fig. 25 View FIGURE 25 D).
