Diagnosis
Diagnosis. This species resembles L. flaviclypeata sp. nov. in having the thorax mostly dark colored (Figs. 4 C, 4D, 5A, 5B), the wing fuscous along R1 only (Fig. 2 G, K), and in the color patterns of abdominal tergites in male (Figs. 8 F, 9A), but can be distinguished from the latter by the paramere with a remarkable wrinkle subdorsally (Fig. 15 C), and the aedeagus needle-shaped apically (Fig. 15 D); see below that species.
Description
Description. Ocellar triangle dark brown, with ca. 2–3 setae above ocellar setae. Frons yellow to brownish yellow. Pedicel brownish yellow; first flagellomere yellow. Clypeus brownish. Palpus yellow to brownish yellow. Mesonotum brownish yellow, with four brown, longitudinal stripes submedially and laterally in male (Fig. 4 C), brown before scutellum and brownish laterally in female. Postpronotal lobe yellow (Fig. 4 D). Acrostichal setulae in ca. 10–12 irregular rows (Fig. 4 C). Scutellum dark brown, yellow at tip in male (Fig. 4 C), brownish, dark brown laterally, brownish yellow at tip in female. Pleura and katepisternum mostly brown above (Fig. 4 D). Meron mostly brownish to brown above (Fig. 4 D). Wing (Fig. 2 G): Costal vein between R2+3 and R4+5 distally with ca. 5–6 peglike spinules on ventral surface. Abdominal tergites dark brown to black (Fig. 8 F, G), with a pair of yellow patches submedially between 2nd to 3rd tergites, 4th tergite with a pair of yellow patches subanteromedially in female (Fig. 8 G). Male terminalia: Epandrium with ca. 6 setae near posterior margin per side (Fig. 15 A). Surstylus rounded apically (Fig. 15 A). Hypandrium with 1 sensillum (Fig. 15 B). Paramere with ca. 6 sensilla aligned above wrinkle and ca. 3 sensilla distally (Fig. 15 C). Measurements.
