Diagnosis.
This species is very similar to
L
.
arcuata
sp. nov.
in the shaped of paramere (
Fig. 21
C), and the patterns of wing (
Fig. 2
H) and abdominal tergites (
Fig.
8
I), but can be distinguished from the latter by having the aedeagus strongly dorsad expanded basally and round apically (
Fig. 21
D).

Fig. 2
H): Costal vein with ca. 7–8 peglike spinules between R2+3 and R4+5 on ventral surface. Abdominal tergites dark brown to black (
Fig.
8
I); second with yellow patches anteriorly and laterally, third with 2 yellow patches anteriorly, fourth and fifth with 4 yellow patches medially, sixth with yellow patch posteriorly. Male terminalia: Epandrium with ca. 19 setae near dorsal to ventral margins per side (
Fig. 21
A). Hypandrium with 1 long sensillum (
Fig. 21
