description: Leucophenga serrateifoliacea Huang & Chen, sp. nov.
(Figs 3 G, 7C, 7D, 9I, 13C, 13D, 30)
Diagnosis. This species is very similar to L. rectifoliacea sp. nov. in the patterns of wing (Fig. 3 G) and abdominal tergites (Fig. 9 I), but can be distinguished from the latter by having the aedeagus thick, curved ventrad and with minute, serrated processes submedially (Fig. 30 D).
Description. Ocellar triangle dark brown, with ca. 3–7 setae above ocellar setae. Frons brown. Pedicel yellow; first flagellomere yellowish brown. Clypeus brownish yellow. Mesonotum nearly yellowish brown, slightly brown before scutellum (Fig. 7 C). Postpronotal lobe yellow. Acrostichal setulae in ca. 14 irregular rows (Fig. 7 C). Scutellum brown medially, dark brown laterally, pale at tip (Fig. 7 C). Pleura with a indistinctive, brown longitudinal stripe above (Fig. 7 D). Katepisternum and meron yellowish (Fig. 7 D). Wing (Fig. 3 G): Costal vein between R2+3 and R4+5 distally with ca. 7–8 peg-like spinules on ventral surface. Abdominal tergites brown to dark brown (Fig. 9 I), with yellow margins on second to fifth; second yellow medially; third to fifth each with 2 pairs of yellow patches submedially on anterior margins; sixth with a pair of yellow patches submedially. Male terminalia: Epandrium with ca. 15 setae near posterior margin and ventral corner per side (Fig. 30 A). Hypandrium with 1 sensillum (Fig. 30 B). Paramere basally narrow, distally broadened, with ca. 4 sensilla and pubescence (Fig. 30 C). Aedeagus almost reticulated completely (Fig. 30 D).

Etymology. A combination of the Latin words “ serratus ” (= serrated) + “ foliaceus ” (= folium), referring to the aedeagus with minute, serrated processes submedially.
Distribution. China (Guangxi, Hainan, Yunnan).
