Forewing yellowish, with an oval pale macula parallel to the costal margin (pterostigma) with dark brown setae above, and dark brown stripes over transversal veins with a transversal jagged line at the midlength of anastomosis of R (
Figure 5F
). Stigma on fork II dark; median cell with basal dark dot. The colouration of the body and wings was observed in specimens preserved in alcohol.
Diameter of eye, in dorsal view, 2.3 times the interocular distance. Anterolateral process of sternum V about 1.5 times the length of the sternum.
Genitalia.
The
structure of segment IX, tergum X and inferior appendages are like the original description by
Martynov
(

) bears ventral and dorsal spines in the dorsal and ventral area of phallus (
Figure 5J–L
). In the original description of Martynov, the apex of phallus is invaginated as in

. The apex of phallus when it is evaginated bears two dorsal teeth in lateral view, a central membranous tube and an apical process slightly broadened at the tip (
Figure 5L
)
