Diagnosis. Antenna yellow. Palpus yellow. Hind femur with a row of weak av (only 3 apical bristles distinct). Wing with brown apical spots on R2+3, R4+5 and M1 slightly separating or confluent, entirely extending to tip of vein; basal edge of apical spots on R2+3 at same vertical level of spot on dm-cu, apical spots on R4+5 slightly beyond vertical level of spot on dm-cu; basal edge of apical spot on M1 beyond that on R4+5, about half length of ultimate sections of M1; a brown round spot on R4+5, situated at middle between levels of both cross veins; broad brown cloud on dm-cu. Abdomen yellow to brownish yellow with grayish white pruinosity.
