Leucophenga quadrifurcata sp. nov.

( Figs. 2 View FIGURE 2 J, 2K, 2L, 3H, 7)

Diagnosis. This species differs from the other species of the interrupta group in having the following characters: wing clouded on r-m and dm-cu crossveins ( Fig. 2 View FIGURE 2 J); aedeagus not bifurcated; aedeagal basolateral process slender basally, quadrifurcated distally ( Fig. 7 View FIGURE 7 D).

Description. Ocellar triangle yellowish brown to dark brown, with 3–4 setae above ocellar setae. Frons brownish yellow to yellowish brown. Pedicel yellowish brown; first flagellomere yellow. Clypeus brown. Scutum yellowish brown ( Fig. 2 View FIGURE 2 K). Postpronotal lobe brownish yellow ( Fig. 2 View FIGURE 2 L). Scutellum yellowish brown ( Fig. 2 View FIGURE 2 K). Wing ( Fig. 2 View FIGURE 2 J): Costal vein between R2+3 and R4+5 distally with 6–8 peg-like spinules on ventral surface. Halter mostly brownish. Abdominal tergites black ( Fig. 3 View FIGURE 3 H); second mostly yellow, but brown posteriorly; third and fourth each with a pair of narrow, yellow patches submedially on anterior margin, yellow laterally; fifth to sixth mostly black. Male terminalia: Epandrium with ca. 10 setae near posterior margin and ventral corner per side ( Fig. 7 View FIGURE 7 A). Paramere nearly rectangular distally, with several weak wrinkles, 2 sensilla and pubescence subdorsally ( Fig. 7 View FIGURE 7 C).
