Leucophenga fuscipalpula Huang & Chen View in CoL , sp. nov.

( Figs. 3F View FIGURE 3 , 7G–I View FIGURE 7 , 10I, 10J View FIGURE 10 , 15E, 15F View FIGURE 15 , 29 View FIGURE 29 )

Diagnosis. This species is most similar to L. brevitabulata sp. nov. in the colour patterns of abdominal tergites in both male ( Fig. 10D, I View FIGURE 10 ) and female ( Fig. 10E, J View FIGURE 10 ), but can be distinguished from the latter in having the paramere nearly quadrate ( Fig. 29C View FIGURE 29 ); aedeagus slender, laterally mostly covered by its long, distoventrally serrated process ( Fig. 29D View FIGURE 29 ).

Description. Ocellar triangle dark brown, with ca. 2 setae above ocellar setae. Frons brownish ( Fig. 7G View FIGURE 7 ). Pedicel brownish yellow; first flagellomere yellow ( Fig. 7G View FIGURE 7 ). Clypeus entirely brownish yellow. Palpus brownish ( Fig. 7G View FIGURE 7 ). Mesonotum mostly brownish yellow ( Fig. 7H View FIGURE 7 ). Postpronotal lobe yellow ( Fig. 7I View FIGURE 7 ). Acrostichal setulae in ca. 12–14 irregular rows ( Fig. 7H View FIGURE 7 ). Scutellum mostly brownish yellow, brownish laterally, yellow at tip ( Fig. 7H View FIGURE 7 ). Pleura with a brown to dark brown, longitudinal stripe above ( Fig. 7I View FIGURE 7 ). Katepisternum and mesopleuron mostly yellow ( Fig. 7I View FIGURE 7 ). Wing ( Fig. 3F View FIGURE 3 ): brownish distally; costal vein between R 2+3 and R 4+5 distally with ca. 5–7 peg-like spinules on ventral surface; R 4+5 and M 1 slightly divergent distally; halter mostly yellowish, with a brownish to brown patch at knob ( Fig. 7I View FIGURE 7 ). Abdominal tergites brown to dark brown, 2nd tergite yellow anteromedially and laterally, 3rd tergite mostly yellowish except for lateral region, setigerous laterally and on posterior margin in males ( Fig. 10I View FIGURE 10 ), 3rd and 4th tergites anteriorly yellow in females ( Fig. 10J View FIGURE 10 ). Male terminalia: Epandrium lacking pubescence, with ca. 10 setae near posterior and ventral margins per side ( Fig. 29A View FIGURE 29 ). Cercus lacking pubescence ( Fig. 29A View FIGURE 29 ). Surstylus pubescent ( Fig. 29A View FIGURE 29 ). Hypandrium with 1 sensillum ( Fig. 29B View FIGURE 29 ). Paramere with ca. 13 sensilla distally ( Fig. 29C View FIGURE 29 ).
