Diagnosis
Diagnosis. This species is mostly similar to L. rugatifolia sp. nov. in having the thorax mostly dark colored (Figs. 5 E, 5F, 6C, 6D), the wing fuscous along R1 only (Fig. 2 M, Q), and the color patterns of abdominal tergites in both male (Fig. 9 D, K) and female, but can be distinguished from the latter by the paramere lacking any remarkable wrinkle and sensillum (Fig. 21 C), and the aedeagus slender, acute apically, slightly expanded distally (Fig. 21 D); see below that species.
Description
Description. Ocellar triangle dark brown, with ca. 0–1 seta above ocellar setae. Frons brownish yellow. Pedicel brownish yellow; first flagellomere yellow. Clypeus and palpus brownish yellow. Mesonotum brownish, mostly with three broad, brown, longitudinal stripes medially and laterally in male (Fig. 5 E), brownish yellow, brown before scutellum in female. Postpronotal lobe yellow (Fig. 5 F). Acrostichal setulae in ca. 8–10 irregular rows (Fig. 5 E). Scutellum dark brown, brownish yellow at tip (Fig. 5 E). Pleura mostly brown (Fig. 5 F). Katepisternum and meron mostly brown in male (Fig. 5 F), brownish in female. Wing (Fig. 2 M): Costal vein between R2+3 and R4+5 distally with ca. 4–6 peg-like spinules on ventral surface. Abdominal tergites dark brown (Fig. 9 D), 2nd tergite with two pairs of yellow patches submedially and laterally, 3rd tergite with a pair of yellow patches subanteromedially. Male terminalia: Epandrium with ca. 4 setae near posterior margin per side (Fig. 21 A). Surstylus rounded apically (Fig. 21 A). Hypandrium with 1 sensillum (Fig. 21 B). Measurements.
