Lateral border areas of pronotum and mesonotum slightly dark brown. Frons ( Fig. 17E View Fig ) brown-blue. Apical part of frons, clypeus ( Fig. 17E View Fig ) and genae ( Fig. 17B, D View Fig ) black. Antennae ( Fig. 17A–E View Fig ) yellowish brown, circular spot at apex of first segment, second segment with oblique spot from base to middle, circular spot at apex dark brown. Forewings ( Fig. 17F View Fig ) dark brown, apex of apical and postcostal cells with 5–6 different-sized transparent spots, inner side of crossveins with 3 dark brown burl spots, middle part big.
