Central sclerite of hypandrium with two postero-lateral processes, distally bulged ( Fig. 210 ). Anterior endophallic sclerites with each arm L-shaped, the longer stem projected posteriorly, ending in a short process, and bearing a large subapical tooth on inner border; mesal pair with outer arms curved, distally acuminate, outer border with a row of small pointed processes; inner arms straight, distally acuminate; posterior sclerites curved, pointed on both ends, slightly dilated ante-apically ( Fig. 211 ). Ninth sternum with a well defined, anterior transverse area and two posterior lobes ( Fig. 217 ).

Male. Color (in 80% ethanol). Body dark brown. Head pattern ( Fig. 208 ), a distinct V-shaped brown area in front and postclypeus; genae brown. Compound eyes dark brown, ocelli hyaline, with ochre centripetal crescents. Antennae cream. Mx1 brown, Mx2 brown, distally cream, Mx3 cream, Mx4 cream, with distal third brown. Tergal lobes of meso- and metathorax dark brown. Legs pale brown. Forewings ( Fig. 206 ). Hindwings ( Fig. 207 ), with brown band from R4+5 to M and a little beyond. Abdomen pale brown.

Female. Color (in 80% ethanol). Body, head, legs, epiproct, paraprocts and wings as in the males; subgenital plate with a long, triangular pigmented area on each side; gonapophyses cream, IX sternum orange. Epiproct and paraprocts cream.

Morphology. As in diagnosis, plus the following: Head ( Fig. 214 ): H/MxW: 1.43; H/D: 2.86, IO/MxW: 0.73, MxW/IO: 1.98. Vertex above the level of the compound eyes. Outer cusp of lacinial tip broad with seven to eight denticles. Forewings ( Fig. 212 ): L/W: 2.52; pterostigma: lp/wp: 5.40; areola postica as in the male, la/ha: 1.43. Hindwings ( Fig. 213 ): l/w: 2.80. Subgenital plate ( Fig. 216 ), wide, posterior margin rounded, with short setae. Gonapophyses ( Fig. 217 ): v1 elongate, slender, acuminate; v2 +3 with long proximal heel; with a row of 14–15 setae on v2; distal process sinuous, acuminate, with microsetae. Ninth sternum ( Fig. 217 ). Paraprocts ( Fig. 215 ), triangular, setae as illustrated, sensory fields with 23–25 trichobothria on basal rosettes. Epiproct ( Fig. 215 ), triangular, setae as illustrated.
