Diagnosis. This species is similar to L. sujuanae sp. nov. in the patterns of abdominal tergites ( Fig. 4 View FIGURE 4 A), but can be differentiated from it by having the black bands of abdominal second to fifth tergites continuous on posterior margins ( Fig. 4 View FIGURE 4 A), the pleura with a curved, brown longitudinal stripe above (running from base of foreleg to base of halter), but sometimes variable in length ( Fig. 3 View FIGURE 3 C), the aedeagus round apically ( Fig. 5 View FIGURE 5 C).

Description. Mesonotum and scutellum mostly brownish yellow ( Fig. 3 View FIGURE 3 B). Postpronotal lobe yellow. Katepisternum yellowish, pale below ( Fig. 3 View FIGURE 3 C). Halter white basally, grayish brown apically ( Fig. 3 View FIGURE 3 C). Abdominal fifth tergite sometimes nearly entirely black in some Taiwan samples. Male terminalia: Epandrium with sparse pubescence and ca. 8 setae near posterodorsal to ventral margins per side; apodeme developed ( Fig. 5 View FIGURE 5 A). Hypandrium with a few minute sensilla subbasolaterally ( Fig. 5 View FIGURE 5 B). Paramere slender, with a few minute sensilla distally ( Fig. 5 View FIGURE 5 B).
