Diagnosis. This species is similar to L. sujuanae sp. nov. in the patterns of abdominal tergites (Fig. 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 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 C), the aedeagus round apically (Fig. 5 C).
Description. Mesonotum and scutellum mostly brownish yellow (Fig. 3 B). Postpronotal lobe yellow. Katepisternum yellowish, pale below (Fig. 3 C). Halter white basally, grayish brown apically (Fig. 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 A). Hypandrium with a few minute sensilla subbasolaterally (Fig. 5 B). Paramere slender, with a few minute sensilla distally (Fig. 5 B).

Leucophenga brevivena sp. nov. (Figs 3 D, 3E, 3F, 4B, 6)
Diagnosis.
