description: Leucophenga euryphylla Huang & Chen, sp. nov.
(Figs 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 C), and the patterns of wing (Fig. 2 H) and abdominal tergites (Fig. 8 I), but can be distinguished from the latter by having the aedeagus strongly dorsad expanded basally and round apically (Fig. 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 E). Postpronotal lobe yellow. Acrostichal setulae in ca. 14–16 irregular rows (Fig. 5 E). Scutellum dark brown, pale at tip (Fig. 5 E). Pleura with a intermittent, brown longitudinal stripe above (Fig. 5 F). Katepisternum and meron yellow (Fig. 5 F). Wing (Fig. 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 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 A). Hypandrium with 1 long sensillum (Fig. 21 B). Paramere basally thin, distally broadened, with ca. 3 sensilla and pubescence (Fig. 21 C). Aedeagus with 1 small acute projection apically (Fig. 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).
