Forewing fork 2 relatively long, sessile, length about 1.3–1.4 times length of fork 3; fork 3 relatively long, with short footstalk, fork about 4 times length footstalk, footstalk length about 1.3–1.4 times length cross-vein m, r-m and m nearly contiguous at fork 3, r-m and m separated by about 0.8–1.0 times length of cross-vein m; fork 4 shorter than fork 3; fork 5 long, length about twice length of fork 4. Hindwing length about 3.3–3.4 times width, fork 2 sessile, length about 1.8 times length of fork 3. Male. Tergum X membranous, fused basally, with two pairs of dorsal processes, a robust mesal pair and a slender pair laterally (Fig. 137), a ventral process also present.
