Diagnosis. Medium-sized species ( Fig. 1A, B ). Basal part of vertex triangular ( Fig. 2D ). Pedicel light-brown ( Fig. 1B ), 1.5 as long as wide ( Fig. 2C ). Lateral carinae of frons joined at eye level. Head apex with a long medial furrow reaching the lower margin of compound eyes in the facial part, almost subequal in length to the broadened part of frons ( Fig. 2A, D ). Frons without spots. Posterior part of pronotum pale, mesonotum uniformly brown ( Fig. 1A, B ). Vein RP on forewing three-branched (RP 1, RP 2 and RP 3) ( Fig. 3A ). Basal part of forewings (almost to apex of clavus) dark yellow with two narrow, brown sashes, which are separated by a wide white stripe. Between pterostigma and apex of the wing wide brown band with two white spots—one oval and one triangular. The distal part of the wing light brown with two oval white spots and one small spot near edge of wing ( Figs 1A, B ).
