ID: Group A - metallic; head contrastingly metallic grey; antennal division (dark fuscous basal ⅔, white apical ⅓) sharply contrasting
The forewing is bronzy-fuscous. The contrast with the metallic grey head is easy enough to see with a hand lens or microscope but the metallic reflections make it more difficult to demonstrate photographically. The antennal division is not always sharply contrasting and may become less contrasting with wear.
