Leucophenga latipenis sp. nov.

(Figs. 2 N, 5G, 5H, 9E, 9F, 22)

Diagnosis. This species resembles L. acuticauda sp. nov. in having the wing fuscous along R1 and costa (Fig. 2 H, N), the color patterns of abdominal tergites in both male (Figs. 8 H, 9E) and female (Figs. 8 I, 9F), and the surstylus acute apically (Figs. 16, 22 A), but can be distinguished from the latter by the aedeagus thick, obviously broadened distally, with a small acute projection distodorsally (Fig. 22 D).

Description. Ocellar triangle dark brown, with ca. 2–3 setae above ocellar setae. Frons brownish in male, yellow to brownish in female, both with an indistinct, brown, longitudinal stripe medially. Pedicel brownish; first flagellomere yellowish. Clypeus brown. Palpus brownish. Mesonotum entirely dark brown in male (Fig. 5 G), brownish yellow, brownish before scutellum in female. Postpronotal lobe yellow (Fig. 5 H). Acrostichal setulae in ca. 8–10 irregular rows (Fig. 5 G). Scutellum entirely dark brown (Fig. 5 G). Pleura and katepisternum mostly brown above (Fig. 5 H). Meron mostly brown above in male (Fig. 5 H), brownish above in female. Wing (Fig. 2 N): Costal vein between R2+3 and R4+5 distally with ca. 4–6 peg-like spinules on ventral surface. Midleg obviously brown on knees. Abdominal tergites mostly black in male (Fig. 9 E), entirely dark brown in female (Fig. 9 F). Male terminalia: Epandrium with ca. 3 setae near posterior margin per side (Fig. 22 A). Paramere with ca. 2 sensilla submedially (Fig. 22 C).
