Thanks for the detail. I totally forgot about neriifolia. If you look at the second group of pics shared by Mr. Muthu, I think there are two species. Secondly, in the lectotype, the wings are not straight. I have seen both of these plants myself in gardens, and I always thought one of them to be hybrid. But you are more experienced so you must be having a better idea. Thanks again. Regards Pankaj
