description: Leucophenga uncinata Huang & Chen, sp. nov.
(Figs 3 I, 7G, 7H, 9K, 13G, 13H, 32)
Diagnosis. This species is separated from other species of the ornata group by having the aedeagus with 1 hooklike process subapically (Fig. 32 D), the paramere short and broadened, nearly rectangular (Fig. 32 C).
Description. Ocellar triangle dark brown, with ca. 2–5 setae above ocellar setae. Frons brown. Pedicel yellow; first flagellomere brown. Clypeus dark brown. Mesonotum yellowish brown (Fig. 7 G). Postpronotal lobe brownish yellow. Acrostichal setulae in ca. 12–15 irregular rows (Fig. 7 G). Scutellum dark brown, pale at tip (Fig. 7 G).
Katepisternum yellow, slightly bring brownish (Fig. 7 H). Meron yellow (Fig. 7 H). Wing (Fig. 3 I): Costal vein between R2+3 and R4+5 distally with ca. 6–8 peg-like spinules on ventral surface. Abdominal tergites brown to dark brown (Fig. 9 K); second yellow medially, with 1 yellow patch laterally; third with a pair of narrow, yellow patches anteriorly; fourth sometimes with a pair of small yellow patches anteriorly; sixth yellow posteriorly. Male terminalia: Epandrium with ca. 14 setae near posterior margin and ventral corner per side (Fig. 32 A). Hypandrium with 1 small sensillum (Fig. 32 B). Paramere with pubescence, lacking sensillum (Fig. 32 C). Aedeagus reticulated, with a small projection medioventrally (Fig. 32 D).
