Diagnosis. This species differs from the other species of the genus Leucophenga in lacking the postocellar seta; with a long seta (nearly equal to ocellar setae in length) above ocellar setae ( Fig. 8D View FIGURE 8 ); Orb 3 located behind Orb 2, separated by distance nearly 1/3 of that between Orb 2 and Orb 1 ( Fig. 8D View FIGURE 8 ); wing apically pointed ( Fig. 4B View FIGURE 4 ); surstylus lacking pubescence and seta except for its margin ( Fig. 33A View FIGURE 33 ); aedeagus wrinkled, mediolaterally with a slender process ( Fig. 33D View FIGURE 33 ).

Description. Body large. Ocellar triangle brown, with ca. 1 small seta above ocellar setae. Frons brownish ( Fig. 8D View FIGURE 8 ). Pedicel brownish yellow; first flagellomere dark yellow ( Fig. 8D View FIGURE 8 ). Clypeus entirely brownish yellow. Palpus dark yellow ( Fig. 8D View FIGURE 8 ). Mesonotum mostly brownish yellow ( Fig. 8E View FIGURE 8 ). Postpronotal lobe dark yellow ( Fig. 8F View FIGURE 8 ). Scutellum mostly brownish yellow ( Fig. 8E View FIGURE 8 ). Acrostichal setulae in ca. 14–16 irregular rows ( Fig. 8E View FIGURE 8 ). Pleura, katepisternum, and mesopleuron mostly dark yellow ( Fig. 8F View FIGURE 8 ). Wing ( Fig. 4B View FIGURE 4 ): clouded distally; costal vein between R 2+3 and R 4+5 distally with ca. 5 or 6 peg-like spinules on ventral surface; R 4+5 and M 1 slightly convergent distally; halter yellow, with dark yellow to brownish yellow patches at stem and knob ( Fig. 8F View FIGURE 8 ). Abdominal tergites black, 2nd tergite yellow anteriorly, medially and laterally, 3rd tergite mostly yellow except for sublateral region, setigerous laterally and on posterior submedial margin, 4th tergite yellow anteriorly in males ( Fig. 11F View FIGURE 11 ). Male terminalia: Epandrium lacking pubescence, with ca. 9 setae medially per side ( Fig. 33A View FIGURE 33 ). Cercus lacking pubescence ( Fig. 33A View FIGURE 33 ). Paramere rounded basally and apically, with ca. 6 sensilla dorsally ( Fig. 33C View FIGURE 33 ).
