Diagnosis.
This species is very similar to
L
.
euryphylla
sp. nov.
in the abdominal tergites patterns (
Fig. 9
C), but can be distinguished from the latter by having the aedeagus basally sturdy, mostly slender and curved, leech-like (
Fig. 27
D).

sp. nov.
, male terminalia in lateral view: A. epandrium, surstylus and cercus; B. hypandrium, paramere, gonopods, aedeagus and aedeagal apodeme; C. paramere; D. aedeagus. Scale bars = 0.1 mm.
Description.
Ocellar triangle dark brown, with ca. 3–6 setae above ocellar setae. Frons yellowish brown. Pedicel yellow, first flagellomere yellowish brown. Clypeus brown to dark brown. Mesonotum medially brownish yellow, with 1 longitudinal stripe and 2 brown patches, laterally brown (

G). Postpronotal lobe yellowish brown. Acrostichal setulae in ca. 14–15 irregular rows (
Fig. 6
G). Scutellum mostly brownish yellow, brown along margin, pale at tip (
Fig. 6

Fig.
6H). Wing (
Fig. 3
D): Costal vein between R2+3 and R4+5 distally with ca. 8–9 peg-like spinules on ventral surface. Abdominal tergites brown to dark brown (
Fig. 9
C); second yellow medially and sublaterally; third with a pair of large, yellow patches submedially on anterior margin; fourth and fifth each with 2 pairs of yellow patches submedially; sixth with a M-shaped yellow patch. Male terminalia: Epandrium with ca. 21 setae near dorsal margin to ventral corner per side (
Fig. 27
A). Hypandrium with 1 sensillum (
