Male ( Figs 1–7 ) Color (in 80 % ethanol). Body pale yellow, with brown and pale brown areas as indicated below. Compound eyes black, ocelli hyaline, with ochre centripetal crescents; head pattern ( Fig. 1 ); a brown band on vertex, from each compound eye to upper part of ocellar group, also, a brown irregular band between compound eyes, limited posteriorly by the postclypeus; each gena with a brown band from lower compound eye to subgenal sulcus. Antennae and maxillary palps pale yellow, Mx4 more pigmented distally. Tergal lobes of meso- and metathorax brown; thoracic pleura with an irregular pale brown band above the level of the coxae. Legs with coxae, trochanters and femora creamy white, tibiae and tarsomeres pale yellow. Forewings almost hyaline, as illustrated ( Fig. 2 ); a brown spot on confluence of Cu2–1A; veins brown. Hindwing ( Fig. 3 ), almost hyaline throughout, veins brown. Structural characters. Compound eyes with interommatidial setae. Outer cusp of lacinial tip broad, with four denticles ( Fig. 4 ). Forewing pterostigma elongate, constricted proximally. Areola postica tall, wide basally, apex round. Rs almost straight, slightly shorter than R4+5, this and R2+3 slightly sinuous. M stem slightly concave proximally, then almost straight. M 5 branched, with M5 forked as illustrated. Hindwing Rs-M fused for a distance, Rs and M of two branches. Paraprocts ( Fig. 5 ) stout, broad, wide proximally, narrowing to round apex; sensory fields with 33–34 trichobothria on basal rosettes; setae as illustrated. Epiproct ( Fig. 5 ) almost straight basally, with one concave area on each antero-lateral corner; sides converging to round posterior border; a pair of long lateral setae in basal half, other setae as illustrated. Hypandrium of one sclerite, anteriorly concave with border strongly sclerotized and triangular distally, with setae as illustrated ( Fig. 6 ). Phallosome ( Fig. 7 ) with side struts continuous with each external paramere, these long, slender, distally pointed, bearing a row of small spines as illustrated. Two pairs of endophallic sclerites; anterior pair elongate, lacking a basal bridge, each sclerite independent, touching inner edge of corresponding side strut; each sclerite broad and almost straight proximally, narrowing to the middle and then curving distally to a pointed apex, as illustrated; posterior pair fused to form a V-shaped structure, each arm of the V distally rounded, ending in a sclerotized ring enclosing a membrane with numerous pores.
