Wing venation: forewing length about 3.3 times width, each with forks 2, 3, 4 and 5 present; fork 2 relatively short, fork 2 footstalk relatively long, length about 1.6– 2.1 times length of cross-vein r -m, length of fork 2 about 1.4–1.7 times length of fork 3; fork 3 short, length of fork 3 about 0.9–1.2 times length of footstalk, footstalk of fork 3 very long, length about 2.6–3.8 times length of cross-vein m. Hind wing length about 4 times width, each with forks 2, 3 and 5 present, all short; fork 2 footstalk relatively long, length about 2 times length of cross-vein r -m.
