Antennae pale brown, scape dark brown. Maxillary palps brown, Mx4 dark brown. Tergal lobes of meso- and metathorax brown. Thoracic pleura brown, with cream spots. Coxae and trochanters cream, femora, tibiae and tarsi brown, coxae with proximal and distal brown spots; fore- and mid femora with three pale brown spots (proximal, middle and distal), hind femora with four brown spots. Wings as in males, abdomen cream, with subcuticular brown spots. Subgenital plate with pigmented areas dark brown ( Fig. 302 ). Clunium and gonapophyses brown. IX sternum pale brown. Epiproct and paraprocts pale brown.

Morphology. Head ( Fig. 301 ): H/MxW: 1.55, H/D: 2.73, IO/MxW: 0.68, MxW/IO: 2.14. Vertex slightly above the level of the compound eyes. Outer cusp of lacinial tips broad, with three broad denticles. Mx4/Mx2: 1.33. Wings and legs as in the male. Forewings ( Fig. 299 ): L/W: 2.49. Pterostigma: lp/wp: 3.82, with abundant setae; areola postica: la/ha: 1.88. Cu1a concave. Hindwings ( Fig. 300 ): l/w: 2.72. Subgenital plate broad, with rounded posterior margin, densely setose. Gonapophyses ( Fig. 303 ): v1 elongate, narrow, acuminate; v2 +3 proximally wider, with short heel; a row of seven macrosetae on v2; distal process sinuous, acuminate, with microsetae. IX sternum ( Fig. 303 ), broadly trapeziform, concave anteriorly, straight posteriorly. Paraprocts broad, oval ( Fig. 304 ), with a macrosetae near each sensory field, these with 23 trichobothria on basal rosettes, setae as illustrated. Epiproct ( Fig. 304 ) broadly triangular, with widely rounded apex, almost as long as wide at its base, with three macrosetae antero-mesally, other setae as illustrated.
