Amorbaea subusta is a moth in the family Xyloryctidae. It was described by Alexey Diakonoff in 1968. It is found on Luzon in the Philippines.[1]
The wingspan is about 25 mm. The forewings are creamy, with a golden gloss, becoming slightly deeper colored towards the base, more so along the dorsum below the fold. There is very narrow blackish-grey suffusion along the dorsum around its middle and sparse sprinkling of dark grey-fuscous scales above the end of the fold, sparsely extended to the middle of the wing breadth. The hindwings are glossy white with a strong golden gloss.[2]
