( Figs 3 E, 8C, 8D, 11E, 15G, 15H, 31) Diagnosis. This species is similar to L . quadripunctata in wing R2+3 vein with a short branch subapically ( Figs 2 H, 3E), but can be distinguished from the latter by having the paramere with an acute projection submedially, and 5 sensilla along apical margin ( Fig. 31 C); epandrium with 13 setae in irregular 2 rows near posterior margin per side ( Fig. 31 A). Description. Ocellar triangle brown, with 5 setae above ocellar setae. Frons brownish yellow. Pedicel yellowish brown; first flagellomere yellow. Clypeus brownish yellow. Palpus brownish yellow, yellowish brown at tip. Mesonotum yellowish brown, brown before scutellum ( Fig. 8 C). Postpronotal lobe brownish yellow ( Fig. 8 D). Acrostichal setulae in 12–14 irregular rows ( Fig. 8 C). Scutellum yellowish brown, yellow at tip ( Fig. 8 C). Pleura with an unapparent, brownish, longitudinal stripe above ( Fig. 8 D). Katepisternum and mesopleuron mostly yellowish brown ( Fig. 8 D). Wing ( Fig. 3 E): Costal vein between R2+3 and R4+5 distally with 6–7 peg-like spinules on ventral surface. Halter slightly brownish apically ( Fig. 8 D). Abdominal tergites dark brown, with yellow patches ( Fig. 11 E). Male terminalia: Epandrium mostly pubescent ( Fig. 31 A).
