This species differs noticeably from other described Oriental species with a lateral preoccipital carina by a combination of large total body length (12-15 mm) and the greatest number (12-15) of hamuli (other large oriental species are usually at most 12 mm in length and have hind wings with at most eleven or twelve hamuli).
