( Figs 3 View FIGURE 3 C, 7I, 7J, 11C, 15C, 15D, 29)

Diagnosis. Abdominal 3rd to 6th tergites dark brown, with small yellow patches sublaterally ( Fig. 11 View FIGURE 11 C); paramere dorsad expanded medially ( Fig. 29 View FIGURE 29 C); aedeagus thick on basal 2/3, slender on distal 1/3 ( Fig. 29 View FIGURE 29 D).

Description. Ocellar triangle yellowish brown, with 4 setae above ocellar setae. Frons yellowish brown to brown. Pedicel yellowish brown; first flagellomere yellow. Clypeus yellowish brown. Palpus brownish yellow. Mesonotum yellowish brown, slightly brown before scutellum ( Fig. 7 View FIGURE 7 I). Postpronotal lobe brownish yellow ( Fig. 7 View FIGURE 7 J). Acrostichal setulae in 11–13 irregular rows ( Fig. 7 View FIGURE 7 I). Scutellum yellowish brown, black at tip and pale around apical scutellar setae ( Fig. 7 View FIGURE 7 I). Pleura slightly brown above ( Fig. 7 View FIGURE 7 J). Katepisternum and mesopleuron mostly brownish yellow; mesopleuron with a brownish patch ( Fig. 7 View FIGURE 7 J). Wing ( Fig. 3 View FIGURE 3 C): Costal vein between R2+3 and R4+5 distally with 6 peg-like spinules on ventral surface. Halter slightly brownish apically ( Fig. 7 View FIGURE 7 I). Male terminalia: Epandrium pubescent submedially, with 16 setae near posterior and ventral margins per side ( Fig. 29 View FIGURE 29 A).
