: Hyaline; venation generally dark especially at the distal ends becoming paler towards the bases with pale spots at the nodus at both outer and inner sides; pterostigma with protruding posterior proximal end into a sharp angle which is dissimilar in both front and hind wings differing in the following: front wing smaller with central fuscous area outlined with pale yellow, hind wing larger with anterior end 2/3 of the length of posterior, bicolored with dark area continuing towards the sharp proximal end of the pterostigma and pale yellow anterior part; CuP slightly proximal to halfway between antenodals in front wings and halfway in hind wings sitting on the top CuP and AA distal at the point where the latter is leaving the wing edge; arculus at second antenodal in front wings and slightly distal to it in hind wings; discoidal cells dissimilar in shape - in front wings anterior side is ~ 1/3 of the posterior and in hind wings anterior side is more than
