(Figs 8–14)
Color. Body pale yellow, with brown and pale brown areas as indicated below. Compound eyes black, ocelli hyaline, with ochre centripetal crescents; head pattern (Fig. 8); a brown area on vertex, close to each compound eye, as illustrated, also a brown band between compound eyes, below the level of the ocellar group, limited posteriorly by the postclypeus; a brown band on each gena, 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. 9); a brown spot on confluence of Cu2–1A; veins brown. Hindwing (Fig. 10), almost hyaline throughout, veins brown.
Structural characters. Compound eyes with interommatidial setae. Outer cusp of lacinial tip broad, with five denticles (Fig. 11). Forewing pterostigma elongate, constricted proximally. Areola postica tall, wide basally, with apex rounded. Rs almost straight, slightly shorter than R4+5, this, and R2+3 slightly sinuous. M stem slightly concave proximally, then almost straight. M 6 branched, with M6 forked, as illustrated. Hindwing Rs-M joined for a distance, Rs 2-branched, M 4-branched. Paraprocts (Fig. 12) stout, broad, irregularly shaped, sensory fields with 32–33 trichobothria on basal rosettes; setae as illustrated. Epiproct (Fig. 12) anteriorly convex, posteriorly rounded, with a field of setae along margin and a pair of large lateral setae in basal half. Hypandrium of one sclerite, anteriorly concave, with anterior border strongly sclerotized, and triangular distally, setae as illustrated (Fig. 13). Phallosome (Fig. 14) with side struts continuous with external parameres, these stout, posteriorly directed, distally pointed, bearing mesally a field of spines near inner edge, as illustrated. Two pairs of endophallic sclerites; anterior pair elongate, lacking a basal bridge, each sclerite independent, slender, bow-shaped, dilated distally; posterior pair basally fused to form a V-shaped structure, each arm of the V proximally slender, widening posteriorly, distally forked; this sclerotized fork forming an almost closed ring, enclosing a membrane with numerous pores.
