description: Leucophenga rugatifolia sp. nov.
(Figs. 2 Q, 6C, 6D, 9K, 25)
Diagnosis. This species is mostly similar to L. gracilenta 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 with a remarkable wrinkle subdorsally and ca. 8 sensilla aligned above (Fig. 25 C), and the aedeagus slender, acute apically, broadened on posteroventral 1/2, slightly spoon-shaped in lateral view (Fig. 25 D).
Description. Ocellar triangle dark brown, with ca. 1–3 seta(e) above ocellar setae. Frons yellow to brownish yellow, brown laterally. Pedicel brownish yellow; first flagellomere yellow to brownish yellow. Clypeus and palpus brownish yellow. Mesonotum entirely dark brown to black in male (Fig. 6 C), brownish yellow, brownish before scutellum in female. Postpronotal lobe brownish in male (Fig. 6 D), yellow in female. Acrostichal setulae in ca. 12–14 irregular rows (Fig. 6 C). Scutellum entirely dark brown in male (Fig. 6 C), entirely brownish in female, yellow at tip in some female. Pleura, katepisternum and meron mostly dark brown in male (Fig. 6 D), mostly brown in female. Wing (Fig. 2 Q): 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 K), 2nd tergite with yellow patches submedially and laterally, 3rd tergite with a pair of yellow patches subanteromedially. Male terminalia: Epandrium with ca. 6 setae near posterior margin per side (Fig. 25 A). Surstylus rounded apically (Fig. 25 A). Hypandrium with 4 sensilla (Fig. 25 B).
