Diagnosis. This species strongly resembles L . spinifera in the colour patterns of abdominal tergites in both male ( Fig. 9G, I ) and female ( Fig. 9H, J ), and the shape of paramere ( Figs. 21C , 22C ), but can be distinguished from the latter in having the postocellar setae minute ( Fig. 6A ); aedeagus laterally with a long, acute, wave-shaped process ( Fig. 22D ). Description. Ocellar triangle dark brown, with ca. 2 setae above ocellar setae. Frons brownish yellow to brownish ( Fig. 6A ). Pedicel brownish yellow; first flagellomere yellow ( Fig. 6A ). Clypeus entirely brownish. Palpus brownish yellow to brownish ( Fig. 6A ). Mesonotum brownish yellow anteromedially, brown to dark brown posteromedially and laterally ( Fig. 6B ). Postpronotal lobe yellow ( Fig. 6C ). Acrostichal setulae in ca. 14–16 irregular rows ( Fig. 6B ). Scutellum brownish yellow to dark brown, black laterally, yellow at tip or around apical scutellar setae ( Fig. 6B ). Pleura with a brown, longitudinal stripe above ( Fig. 6C ). Katepisternum and mesopleuron mostly yellow ( Fig. 6C ). Wing ( Fig. 2F ): slightly clouded; 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 brown to dark brown patch at knob ( Fig. 6B ). Mid and hindlegs brownish on femur in some specimens ( Fig. 6B, C ). Abdominal tergites dark brown to black, 2nd tergite yellow to brownish medially and laterally, 3rd tergite mostly yellow to brownish (especially in the posterior margin) except for lateral region, setigerous laterally and on posterior margin in males ( Fig. 9I ), yellow anteriorly in females ( Fig. 9J ), 4th tergite yellow anteriorly. Male terminalia: Epandrium lacking pubescence, with ca. 11 setae near posterior and ventral margins per side ( Fig. 22A ). Cercus lacking pubescence ( Fig. 22A ). Surstylus pubescent ( Fig. 22A ). Hypandrium with 1 sensillum ( Fig. 22B ). Paramere narrow basally, with ca. 7 sensilla distally ( Fig. 22C ). Measurements and indices.
