Leucophenga euryphylla Huang & Chen , sp. nov.
( Figs 2 View FIGURE 2 H, 5E, 5F, 8I, 11E, 11F, 21)
Diagnosis. This species is very similar to L. arcuata sp. nov. in the shaped of paramere ( Fig. 21 View FIGURE 21 C), and the patterns of wing ( Fig. 2 View FIGURE 2 H) and abdominal tergites ( Fig. 8 View FIGURE 8 I), but can be distinguished from the latter by having the aedeagus strongly dorsad expanded basally and round apically ( Fig. 21 View FIGURE 21 D).
Description. Ocellar triangle dark brown, with ca. 3–5 setae above ocellar setae. Frons yellowish brown. Pedicel yellowish; first flagellomere yellowish brown. Clypeus brownish. Mesonotum brownish yellow and with 2 brown patches medially, brown laterally ( Fig. 5 View FIGURE 5 E). Postpronotal lobe yellow. Acrostichal setulae in ca. 14–16 irregular rows ( Fig. 5 View FIGURE 5 E). Scutellum dark brown, pale at tip ( Fig. 5 View FIGURE 5 E). Pleura with a intermittent, brown longitudinal stripe above ( Fig. 5 View FIGURE 5 F). Katepisternum and meron yellow ( Fig. 5 View FIGURE 5 F). Wing ( Fig. 2 View FIGURE 2 H): Costal vein with ca. 7–8 peglike spinules between R2+3 and R4+5 on ventral surface. Abdominal tergites dark brown to black ( Fig. 8 View FIGURE 8 I); second with yellow patches anteriorly and laterally, third with 2 yellow patches anteriorly, fourth and fifth with 4 yellow patches medially, sixth with yellow patch posteriorly. Male terminalia: Epandrium with ca. 19 setae near dorsal to ventral margins per side ( Fig. 21 View FIGURE 21 A). Hypandrium with 1 long sensillum ( Fig. 21 View FIGURE 21 B). Paramere basally thin, distally broadened, with ca. 3 sensilla and pubescence ( Fig. 21 View FIGURE 21 C). Aedeagus with 1 small acute projection apically ( Fig. 21 View FIGURE 21 D).

Type specimens. Holotype ♂ (SCAU, No. 121798), CHINA: Hesong, Menghai, Yunnan, alt. 1900m, 9.iv.2011, ex tree trunk, SJ Yan. Paratypes: 9♂, 10♀ (2♂, 3♀ in KIZ; 7♂, 7♀ in SCAU, Nos 121791 –97, 121799 – 1805), same data as holotype, JM Lu, ZF Shao, YR Su, SJ Yan.
Etymology. A combination of the Greek words: eurys (= broad) + phyllon (= leaf), referring to the aedeagus expanded subbasally.
Distribution. China (Yunnan).
