( Figs 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 B); the katepisternum yellow ( Fig. 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 C). Postpronotal lobe yellow. Acrostichal setulae in ca. 12–14 irregular rows ( Fig. 6 C). Scutellum dark brown, yellow at tip ( Fig. 6 C). Katepisternum and meron mostly yellow ( Fig. 6 D). Wing ( Fig. 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 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 A). Hypandrium lacking sensillum ( Fig. 25 B). Paramere pubescent and with ca. 2 sensilla submedially ( Fig. 25 C). Aedeagus reticulated, distally round and curved ventrad ( Fig. 25 D). Measurements.
