Head pattern ( Fig. 5 ); a slender brown band from each compound eye to epistomal sulcus; genae with brown ochre wide band from lower margin of each compound eye to anterior tentorial pit, postgenae, mandibles, maxillae and labium cream. Antennae pale brown, apex of flagellomeres cream. Maxillary palps pale brown, Mx4 brown distally. Pronotum cream; tergal lobes of meso- and metathorax pale brown, with brown spots; thoracic pleura pale cream with small brown spots. Fore- and middle legs pale brown, coxae, trochanters, femora and tibiae cream, tarsi pale brown. Forewings almost hyaline ( Fig. 3 ), with pale brown areas proximally, vein ends dark brown, surrounded by pale brown areas; pterostigma pale brown with central hyaline area. Hindwings hyaline, with brown spots at vein ends. Abdomen pale cream. Hypandrium cream. Phallosome dark brown. Epiproct and paraprocts cream, with brown subcuticular spots.

Morphology. Head ( Fig. 5 ): H/MxW: 1.42; H/D: 2.97, IO/MxW: 0.71, MxW/IO: 1.98. Vertex slightly above the level of the compound eyes. Outer cusp of lacinial tip broad, with four denticles. Mx4/Mx2: 1.31. Forewings ( Fig. 3 ): L/W: 2.43. Pterostigma wider in the middle; lp/wp: 3.60; areola postica: la/ha: 1.85. Hindwings ( Fig. 4 ): l/ w: 2.79. Side sclerites of hypandrium small, irregular; central sclerite as in diagnosis ( Fig. 7 ). Phallosome ( Fig. 8 ) Y-shaped anteriorly, side struts slender; external parameres membranous, distally narrow and rounded, bearing pores; lateral sclerites proximally curved inwards and attached to the anterior pair, distally acuminate; anterior pair curved and close together proximally; mesal pair with arms curved outwards and distally blunt; postero-mesal pair distally curved, acuminate, ending in two pointed teeth. Paraprocts ( Fig. 6 ) broad, oval, with rounded posterior margin, setal field distal, with abundant short and medium sized setae and macrosetae near the outer margin; sensory fields with 19 trichobothria on basal rosettes. Epiproct ( Fig. 6 ) wide, convex anteriorly, posteriorly rounded, setae as illustrated.
