Male. Color. Body brown. Head pattern ( Fig. 66 ), with a dark brown diagonal band from the inner border of each compound eye to the epistomal sulcus, under the level of the ocellar triangle. Compound eyes black, ocelli hyaline, with ochre centripetal crescents. Anteclypeus, postclypeus and labrum dark brown. Genae brown. Postgenae light brown. Antennae pale brown; flagellomeres with apices cream. Maxillary palps: Mx1–2 creamy; Mx3–4 pale brown. Tergal lobes of meso- and metathorax brown, with light brown edges. Thoracic pleura brown, with light brown areas. Legs pale brown, fore- coxae brown, fore- and mid femora with brown spots proximally and distally; hind femora with brown spots medially and distally. Wings hyaline, veins brown. Forewings mostly hyaline, veins with brown spots distally, at wing margin, a brown band from Cu1 to wing margin ( Fig. 64 ). Hindwings with brown spots distally on veins at wing margin. Abdomen pale brown, with subcuticular ochre spots. Hypandrium brown. Epiproct and paraprocts light brown. Phallosome brown, endophallic sclerites dark brown.

Outer cusp of lacinial tips broad, with four short, rounded denticles. Mx4/Mx2: 1.29. Forewings ( Fig. 64 ): L/W: 2.64. Pterostigma: lp/wp: 4.31, areola postica tall, narrow, apically rounded: al/ah: 1.12, R4+5sinuous, M six-branched, M4 and M6 distally forked. Hindwings ( Fig. 65 ): l/w: 2.93; M three-branched. Hypandrium ( Fig. 67 ), posterior processes proximally wide, narrowing distally, phallosome Y-shaped anteriorly, side struts slender; external parameres wide, apices rounded, bearing pores ( Fig. 69 ); four pairs of endophallic sclerites, anterior pair thick, elongate, with apices rounded; lateral sclerites laminar, wide basally, posteriorly acuminate; mesal pair basally wide, bow shaped, distally hooked outwards ( Fig. 69 ). Paraprocts ( Fig. 68 ) robust, oval, with distal setal field and macrosetae as illustrated; sensory fields with 20 trichobothria on basal rosettes. Epiproct ( Fig. 68 ) semioval, with short and long setae, with a field of microspicules anteriorly and posteriorly.
