Compared with specimens from Ceylon preserved in the Zoologisches Forschungsmuseum Alexander Koenig,Bonn, Germany by Dieter Stuning for the above mentioned paper

SS: This individual is uploaded twice. SO one of them should be deleted. Vide Hampson, (1895), Cusiala raptaria has curved postmedial beyond cell on HW, while boarmoides has angled postmedial. Both species display polymorphism. This feature is not clearly visible in this and the rest of the individuals. However, as D. Stuning has compared these individuals with dissected specimens in the museum, I am okay with ID.

Agree with the ID
