Leucophenga rhombura View in CoL sp. nov.

( Figs. 2 View FIGURE 2 P, 6A, 6B, 9I, 9J, 24)

Diagnosis. This species is mostly similar to L. rugatifolia sp. nov. in having the thorax mostly dark colored ( Fig. 6 View FIGURE 6 A–D), the wing fuscous along R1 only ( Fig. 2 View FIGURE 2 P, Q), and the shape of paramere ( Figs. 24 View FIGURE 24 , 25 View FIGURE 25 C), but can be distinguished from the latter by the hypandrium lacking any sensillum ( Fig. 24 View FIGURE 24 B), and the aedeagus slender, narrow on posteroventral 1/3 and apically, slightly rhombic distally in lateral view, with 1 sensillum distally ( Fig. 24 View FIGURE 24 D); see below that species.

Description. Ocellar triangle dark brown, with ca. 2–3 setae above ocellar setae. Frons brownish yellow, brown laterally. Pedicel and first flagellomere brownish yellow. Clypeus brown. Palpus yellow. Mesonotum entirely dark brown to black in male ( Fig. 6 View FIGURE 6 A), brownish yellow, with three brown, longitudinal stripes medially and laterally in female. Postpronotal lobe brown in male ( Fig. 6 View FIGURE 6 B), brownish yellow in female. Acrostichal setulae in ca. 10–12 irregular rows ( Fig. 6 View FIGURE 6 A). Scutellum entirely dark brown to black ( Fig. 6 View FIGURE 6 A). Pleura, katepisternum and meron mostly dark brown in male ( Fig. 6 View FIGURE 6 B), mostly brown in female. Wing ( Fig. 2 View FIGURE 2 P): Costal vein between R2+3 and R4+5 distally with ca. 5–6 peg-like spinules on ventral surface. Abdominal tergites dark brown, 2nd tergite with two pairs of yellow patches submedially and laterally, 3rd tergite with a pair of yellow patches submedially, 4th tergite with a pair of yellow patches subanteromedially in male ( Fig. 9 View FIGURE 9 I), 3rd tergite with a pair of yellow patches subanteromedially in female ( Fig. 9 View FIGURE 9 J). Male terminalia: Epandrium with ca. 4 setae near posterior margin per side ( Fig. 24 View FIGURE 24 A). Surstylus rounded apically ( Fig. 24 View FIGURE 24 A). Paramere with a wrinkle remarkable subdorsally and ca. 9 sensilla aligned above ( Fig. 24 View FIGURE 24 C).
