Ceratarcha Swinhoe, 1894 species known from India
Ceratarcha umbrosa Swinhoe, 1894
Ceratarcha clathralis Swinhoe, 1894

JR: Agree with the identification, it's a male.

RS: Agree with ID. C. clathralis should be mentioned as a similar-looking species, ideally with the link to the OD if possible, as there are no images of clathralis available (C. umbrosa live images can be found here- https://www.inaturalist.org/observations?place_id=any&quality_grade=research&taxon_id=714803)
