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 (

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 (

Diagnosis.
This species is similar to
L. zhengfangae
in the patterns of abdominal tergites (
Fig. 4
B), but can be differentiated from it by having the mesonotum mostly yellowish brown and the scutellum brown (
Fig. 3
E), the pleura with a dark brown longitudinal stripe above (
Fig. 3
F), the katepisternum dark brown above, yellow below (
Fig. 3
F), the aedeagus acute apically (
Fig. 6
C).
Description.
Halter white basally, brownish distally (
Fig. 3
F). Abdominal tergites brownish; second yellow medially and a small patch laterally; third and fourth each with narrow bands on anterior margins and a small patch laterally (
Fig. 4
B). Male terminalia: Epandrium with pubescence except for anterior margin and ca. 10 setae near posterodorsal to ventral margins per side; apodeme developed (
Fig. 6
A). Hypandrium with a few minute, sensilla subbasolaterally (
Fig. 6
B). Paramere slender, with a few minute sensilla distally (
Fig. 6
B).
