Diagnosis: Hypandrium deeply cleft posteriorly in the middle; each posterior lobe anteriorly broad, projected on the sides, with a narrow, slender, mid sized posteri- or process of triangular apex, ( Fig. 11 ). Mesal pair of endophallic sclerites stout, L-shaped, distally curved outwards. Lateral endophallic sclerites narrow, almost transverse ( Fig. 12 ). IX sternum of three distinct areas; basal with concentric lines on each postero-lateral corner; middle area with sides converging posteriorly to truncate apex; anterior area with anterior border straight, and posterior border with two broad lobes ( Fig. 17 ).

Male: Color: Body brown. Head pattern ( Fig. 9 ), a dark brown transverse band from the inner border of each compound eye to the ocellar triangle and to the epistomal sulcus. Vertex, occiput and postocciput light brown. Compound eyes black, ocelli hyaline, with dark ochre centripetal crescents. Labrum, anteclypeus and postclypeus dark brown. Genae dark brown, postgenae light brown. Antennae: scape dark brown, pedicel and flagellomeres pale brown, cream apically. Maxillary palps: Mx₁ creamy; Mx₂₋₄ brown. Prothorax cream, with small light brown pronotal stripe. Tergal lobes of meso- and metathorax creamy, with small light brown spots. Mesothoracic pleura dark brown, with cream small areas; metathoracic pleura cream, with small brown areas. Legs pale brown, fore- coxae brown, mid-coxae cream, with small brown spot, hind-coxae cream; trochanters and femora cream, femora with two small brown rings; tibiae and tarsi pale brown. Wings almost hyaline, with small brown spots, veins dark brown. Forewings mostly hyaline, pterostigma with large proximal and distal dark brown bands, veins with dark brown spots distally, at wing margin; a brown submarginal band from R₄₊₅ to areola postica; a dark brown spot in distal part of Cu₁ and end of cell cu₂ ( Fig. 7 ). Hindwings with brown spots on vein ends, R₄₊₅ and M, at wing margin. Abdomen cream, with small ochre subcuticular spots; clunium and phallosome brown. Hypandrium brown to cream. Epiproct and paraprocts light brown.

Morphology: Head ( Fig. 9 ): H/MxW: 1.44; H/D: 2.61; IO/ MxW: 0.75. Vertex almost at the same level of the upper border of the compound eyes. Outer cusp of lacinial tips broad, with seven denticles. Mx₄/Mx₂: 1.32. Forewings ( Fig. 7 ): FW/W: 2.50. Pterostigma: lp/wp: 4.07, areola postica tall, almost as tall as wide, rounded apically: al/ ah:1.50,R₂₊₃and R₄₊₅ sinuous,M five-branched,M₅ forked. Hindwings ( Fig. 8 ): HW/w: 2.79; M three-four-branched, if M is three-branched, then M₂ is forked. Hypandrium ( Fig. 11 ), of a single sclerite, resulting from the fusion of the proximal ends of the side sclerites to the central sclerite, with abundant setae. Phallosome Y-shaped anteriorly, side struts slender; external parameres wide, bearing pores,without teeth on outer margin ( Fig. 12 ); three pairs of endophallic sclerites, anterior pair laminar, like wide lobes, S-shaped; mesal pair elongate, converging basally and wide, apically diverging and curved inward ( Fig. 12 ). Paraprocts ( Fig. 10 ) elliptical, with distal setal field and macrosetae,two of them spatulate apically,as illustrated; sensory fields with 25-28 trichobothria on basal rosettes. Epiproct ( Fig. 10 ) semioval, with short setae and two lateral macrosetae distally, with a field of microspicules and short setae anteriorly.

Forewings ( Fig.13 ) FW/W:2.46;pterostigma:lp/ wp: 4.04, elongate, wider in the middle; M five branched, M5 forked distally; areola postica: la/ha: 1.63, tall, broadly triangular, apically rounded. Hindwings ( Fig. 14 ) HW/w: 2.85; M three-branched. Subgenital plate ( Fig. 16 ) wide, setose, with apical border rounded.
