Diagnosis. The new subspecies differs from the nominate one by larger size and green coloration (vs a small size and yellow-green coloration in nominate subspecies). Females have a gray-brown coloration.
Description. Male morphology: Wingspan 38-46 mm, forewing length 18-23 mm. Eye gray. Antenna light brown. Head light brown-green or olive. Labial palpus light brown-green (its length equal to two eye’s diameter). Thorax green. Patagium and tegula green. Outer side of legs green, inner side of legs light brown-green ventrally, tarsus light brown-green. Forewing upperside usually green, but sometimes light gray-green; antemedial and postmedial lines clear; subterminal line dashed. Forewing underside light green, almost white in the basal and anal areas; antemedial line lacks; postmedial line unclear; subterminal line dashed. Hindwing upperside light green, creamy in the anal area; medial line clear; subterminal line dashed. Hindwing underside light green; postmedial line clear, curved; subterminal line dashed. Abdomen light green. Male genitalia: The male genitalia typical for the genus. Tegumen wide, with two tergal appendages (tergal appendages are coalescent in some specimens). Aedeagus long, thin, curved apically, the basal part wide. Female morphology: Wingspan 42-44 mm, forewing length 23-25 mm. Eye light brown. Antenna light brown. Head light brown. Labial palpus light brown, short (its length equal to eye’s diameter). Thorax light brown or olive. Patagium and tegula green light brown or olive. Legs light brown or olive.
