Diagnosis. This species is somewhat similar to L. angusta in the color patterns of abdominal tergites (Fig. 4 D, 4E), but can be distinguished from the latter by having the mesonotum yellow (Fig. 1 J), the aedeagus thick and pubescent on distal 1/3 (Fig. 6 B).

Description. Male and female: Frons yellow to yellowish brown. Pedicel mostly yellow; first flagellomere yellowish. Palpus light brown in male and female. Acrostichal setulae in ca. 12–14 irregular rows (Fig. 2 G). Postpronotal lobe yellow (Fig. 2 H). Scutellum nearly yellow (Fig. 2 G). Pleura yellow below, brownish yellow above (Fig. 2 G, 2H). Halter brownish yellow, white apically (Fig. 2 H). Abdominal tergites yellow, with brown patches (Fig. 4 D, 4E). Male terminalia: Epandrium with 14 setae near posterior margin and ventral corner per side (Fig. 6 A). Paramere lacking sensilla (Fig. 6 B
