ID: Cusiala raptaria form disterminata Walker, 1860
OD:Boarmia disterminata- List of the specimens of lepidopterous insects in the collection of the British Museum vol xxi Page 491. https://www.biodiversitylibrary.org/item/120012#page/757/mode/1up
Cusiala disterminata: F.Moore - Lepidoptera of Ceylon, Vol 3 page 408.
Iyer, G., D. Stüning & S. Sondhi. 2021. An inventory of geometrid moths (Lepidoptera: Geometroidea: Geometridae) of Kalakad-Mundanthurai Tiger Reserve, India. Journal of Threatened Taxa 13(13): 19887–19920. 7105.13.13.19887-19920. Image- Plate 8 # 151
Compared with specimens from Ceylon preserved in the Zoologisches Forschungsmuseum Alexander Koenig,Bonn, Germany by Dieter Stuning for the above mentioned paper
SS: 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.
