Treatment

Leucophenga piscifoliacea Huang & Chen , sp. nov.

( Figs 3 View FIGURE 3 E, 6I, 6J, 9D–G, 12I, 12J, 28)

Diagnosis. This species is very similar to L. rectifoliacea sp. nov. in the patterns of wing ( Fig. 3 View FIGURE 3 E) and abdominal tergites ( Fig. 9 View FIGURE 9 D–G), but can be distinguished from the latter by having the paramere curved basally and distally ( Fig. 28 View FIGURE 28 C); aedeagus with 1 triangular projection subbasally and reticulated distally ( Fig. 28 View FIGURE 28 D).

Description. Ocellar triangle dark brown, with ca. 2–5 setae above ocellar setae. Frons yellowish brown to dark brown. Pedicel yellow; first flagellomere brown. Clypeus brown to dark brown. Mesonotum yellowish brown to brown, with 3 dark brown longitudinal stripes on anterior 2/3: broad medially and thin laterally in holotype ( Fig. 6 View FIGURE 6 I), sometimes without any stripes in some paratypes. Postpronotal lobe yellow. Acrostichal setulae in ca. 14–16 irregular rows ( Fig. 6 View FIGURE 6 I). Scutellum brown, pale at tip ( Fig. 6 View FIGURE 6 I). Katepisternum mostly brownish yellow, brown anterior corner ( Fig. 6 View FIGURE 6 J). Meron brown ( Fig. 6 View FIGURE 6 J). Wing ( Fig. 3 View FIGURE 3 E): Costal vein between R2+3 and R4+5 distally with ca. 6–8 peg-like spinules on ventral surface. Abdominal tergites brown to black ( Fig. 9 View FIGURE 9 D–G); second yellow medially, each with a yellow patch laterally; third with a pair of narrow, yellow patches submedially on anterior margin; fourth and fifth each with a pair of yellow patches submedially; sixth yellow medially in holotype ( Fig. 9 View FIGURE 9 D); sometimes fourth and fifth with a variety changes in some paratypes ( Fig. 9 View FIGURE 9 E–G). Male terminalia: Epandrium with ca. 19 setae near posterior margin and ventral corner per side ( Fig. 28 View FIGURE 28 A). Hypandrium with 1 small sensillum ( Fig. 28 View FIGURE 28 B). Paramere with ca. 3 sensilla submedially and pubescence distally ( Fig. 28 View FIGURE 28 C).
