Paramere; D. Aedeagus. Scale bars = 0.1 mm. Diagnosis. This species strongly resembles L . varinervis 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 distinct ( Fig. 5M ); aedeagus apically hook-shaped, laterally mostly covered by its long process ( Fig. 21D ); see below for that species. Description. Ocellar triangle dark brown, with ca. 2 or 3 setae above ocellar setae. Frons brownish ( Fig. 5M ). Pedicel brownish yellow; first flagellomere yellow ( Fig. 5M ). Clypeus entirely brown. Palpus brownish yellow ( Fig. 5M ). Mesonotum brownish yellow, usually brownish to brown in front of scutellum ( Fig. 5N ). Postpronotal lobe yellow ( Fig. 5O ). Acrostichal setulae in ca. 12–14 irregular rows ( Fig. 5N ). Scutellum brownish yellow to dark brown, black laterally, yellow at tip ( Fig. 5N ). Pleura with a brown to dark brown, longitudinal stripe above ( Fig. 5O ). Katepisternum and mesopleuron mostly yellow ( Fig. 5O ). Wing ( Fig. 2E ): nearly hyaline; costal vein between R 2+3 and R 4+5 distally with ca. 4–6 peg-like spinules on ventral surface; R 4+5 and M 1 slightly divergent distally; halter mostly yellowish, with a brownish patch at knob ( Fig. 5N ). Abdominal tergites dark brown, 2nd tergite yellow to brownish medially and laterally, 3rd tergite mostly yellow except for lateral region, setigerous laterally and on posterior margin in males ( Fig. 9G ), 3rd tergite yellow anteriorly in females ( Fig. 9H ), 4th tergite yellow anteriorly. Male terminalia: Epandrium lacking pubescence, with ca. 7 setae near posterior and ventral margins per side ( Fig. 21A ). Cercus lacking pubescence ( Fig. 21A ). Surstylus pubescent ( Fig. 21A ). Hypandrium with 1 sensillum ( Fig. 21B ). Paramere narrow basally, pubescent medially, with ca. 5 sensilla distally ( Fig. 21C ). FIGURE 21.
