Diagnosis.
This species is very similar to
L
.
rectifoliacea
sp. nov.
in the patterns of wing (
Fig. 3
E) and abdominal tergites (
Fig. 9
D–G), but can be distinguished from the latter by having the paramere curved basally and distally (
Fig. 28
C); aedeagus with 1 triangular projection subbasally and reticulated distally (
Fig. 28
D).
Description.
Ocellar triangle dark brown, with ca. 2–5 setae above ocellar setae. Frons yellowish brown to dark brown. Pedicel yellow; first flagellomere brown. Clypeus brown to dark brown. Mesonotum yellowish brown to brown, with 3 dark brown longitudinal stripes on anterior 2/3: broad medially and thin laterally in
holotype
(
Fig.
6
I), sometimes without any stripes in some
paratypes
. Postpronotal lobe yellow. Acrostichal setulae in ca. 14–16 irregular rows (
Fig.
6
I). Scutellum brown, pale at tip (
Fig.
6
I). Katepisternum mostly brownish yellow, brown anterior corner (
Fig. 6
J). Meron brown (
Fig. 6
J). Wing (
Fig. 3
E): Costal vein between R2+3 and R4+5 distally with ca. 6–8 peg-like spinules on ventral surface. Abdominal tergites brown to black (
Fig. 9
D–G); second yellow medially, each with a yellow patch laterally; third with a pair of narrow, yellow patches submedially on anterior margin; fourth and fifth each with a pair of yellow patches submedially; sixth yellow medially in
holotype
(
Fig. 9
D); sometimes fourth and fifth with a variety changes in some
paratypes
(
Fig. 9
E–G). Male terminalia: Epandrium with ca. 19 setae near posterior margin and ventral corner per side (
Fig. 28
A). Hypandrium with 1 small sensillum (
Fig. 28
B). Paramere with ca. 3 sensilla submedially and pubescence distally (
Fig. 28
C).
