Head pattern ( Fig. 42 ), vertex light brown, with brown spots; front with transverse brown spots; an ochre transverse band between the inner border of each compound eye below the lower edge of the ocellar triangle to the epistomal sulcus; a cream diagonal band from the inner border of each compound eye to epistomal sulcus at the level of the antennal fossae. Compound eyes dark brown, ocelli hyaline with ochre centripetal crescents. Labrum, anteclypeus, postclypeus and mandibles dark brown. Genae dark brown. Postgenae light brown. Antennae: scape brown; pedicel and flagella pale brown, flagellomeres 1–10 with apices cream. Maxillary palps: Mx1 cream, Mx2–4 dark brown, cream basally. Tergal lobes of meso- and metathorax dark brown, with light brown edges. Thoracic pleura pale brown, with large ochre areas on mesopleura. Legs: coxae with small ochre spot basally, fore- coxae and trochanters brown; coxae, trochanters and femora of mid- and hind legs light brown; femora with two brown spots; tibiae and tarsi pale brown. Wings hyaline ( Figs 40–41 ). Forewing pterostigma hyaline ( Fig. 40 ), with large proximal and distal dark brown bands; brown spots on vein ends at wing margin. Hindwings ( Fig. 41 ) with brown spots on vein ends at wing margin. Abdomen light brown to cream, with subcuticular ochre spots. Clunium pale brown. Hypandrium dark brown. Epiproct and paraprocts light brown.

Pterostigma: lp/wp: 5.17, areola postica tall, apically rounded: al/ah: 1.36, R4+5 sinuous, M six-branched, M2, M4–6 forked or sometimes M2–6 forked and R4+5 forked. Hindwings ( Fig. 41 ): l/w: 2.71; Rs three–four branched; M four–branched. Hypandrium ( Fig. 43 ), posterior projections of hypandrium dilated mesally, with preapical setae on inner margin, setose as illustrated; phallosome V-shaped anteriorly, side struts slender; external parameres laminar, wide, apices rounded, bearing pores and sclerotized short teeth ( Fig. 45 ); three pairs of endophallic sclerites, anterior pair thick, elongate, narrowing distally, pointed, and converging posteriorly; lateral sclerites C-shaped, wider distally; mesal pair wide and curved inwards, mesal sclerite processes distally curved outwards, elongate and truncate apically. Paraprocts ( Fig. 44 ) robust, with distal setal fields and macrosetae as illustrated; sensory fields with 24–26 trichobothria on basal rosettes. Epiproct ( Fig. 44 ) semioval, with short and long setae, two lateral macrosetae, a setal field on posterior border and a posterior field of microspicules.
